  Introduction to DTD DTD (Ethylene Sulfate)  is a white crystalline solid or powder. Its unique heteroatomic five-membered ring structure containing both sulfur and oxygen endows DTD with excellent physicochemical properties and broad application prospects.   The application of DTD in lithium-ion batteries In 1998, Mitsubishi Chemical Corporation of Japan first investigated the application of DTD in lithium metal battery systems and filed a patent. In 2002, the Sano and Maruyama team subsequently reported the innovative application of using DTD as an Additive For Li-ion Battery.   1. As a Film Forming Additive,  DTD can improve negative electrode stability. Xuecheng Li et al. demonstrates that DTD can preferentially decompose on the graphite anode, forming a uniform and stable Solid Electrolyte Interphase (SEI). This film effectively inhibits continuous electrolyte decomposition on the anode surface, suppresses graphite exfoliation, and enhances the stability of the graphite anode.   2. Enhance the initial discharge efficiency of lithium-ion batteries. Zhiying Ding et al. compared the initial charge and discharge capacities of  DTD with 1,2-PS and 1,3-PCS. The results showed that DTD could increase the initial discharge capacity, and improve the first discharge efficiency of the Secondary Battery. 3. Improve battery high-temperature storage performance. Jian Xia et al. studied the synergistic effect of  DTD and VC, which can reduce the gas production during high-temperature storage and suppress volume expansion of  lithium-ion batteries. In addition, it can inhibit irreversible capacity decay and reduce the increase in impedance of batteries after high-temperature storage. As a High Temperature Battery Additive, it can improve the high-temperature storage performance of batteries. 4. Strengthen the cycling performance of batteries and rate capability. As Low Impedance Additives, DTD can form the Solid Electrolyte Interphase (SEI) rich in inorganic components, which promotes the migration of lithium ions and reduces the internal resistance. In addition,  DTD is also one of the  Rate Capability Additives and Cycle Life Additives. Other fields As a hydroxyethyl reagent, DTD has a wide range of applications in organic synthesis. It can not only be used for synthesizing pharmaceutical intermediates, but also for manufacturing various chemicals. It is used as a raw material for synthesizing heterocyclic compounds in applications such as gelatin hardening agents, antihypertensive drugs, and new dual-surfactants.

Introduction to Methyl (2,2,2-trifluoroethyl) Carbonate FEMC Basic Chemical Information Name: Methyl (2,2,2-trifluoroethyl) Carbonate Molecular formula: C₄H₅F₃O₃ Molecular weight: 158.08 Boiling point: 103 °C (760 mmHg) FEMC is a fluorinated derivative of the conventional lithium-ion Electrolyte Solvent EMC (ethyl methyl carbonate). The introduction of fluorine markedly enhances thermal and electrochemical stability. The –CF₃ group in FEMC lowers both the HOMO and LUMO energy levels, raising the electrolyte’s oxidative-decomposition potential. Thanks to the comprehensive advantages imparted by fluorine, FEMC has become an essential Battery Electrolyte Additive or Fluorinated Solvent for high-safety, high-energy-density lithium-ion battery systems.   The application of Methyl (2,2,2-trifluoroethyl) Carbonate in lithium-ion batteries 1. Enhanc cycling stability under high-voltage conditions Zhengcheng Zhang et al. investigated the beneficial effect of FEMC on the cycling performance of high-voltage LMNO cells. Using a fluorinated blend of 1.2 M LiPF₆ in F-AEC (4-[2,3,3,3-tetrafluoro-2-(trifluoromethyl)propyl]ethylene carbonate), FEMC (2,2,2-trifluoroethyl methyl carbonate) and F-EPE (1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether), the electrolyte exhibited excellent oxidation resistance at 5 V. The incorporation of FEMC markedly enhanced the cycle life of the High Voltage Battery.   2. Strengthen cathode stability while suppressing interfacial side reactions at the anode   Yu-Mi Lee et al. demonstrated that adding 5 % FEMC to NCM523 cells effectively suppresses transition-metal dissolution from the LiNi₀.₅Co₀.₂Mn₀.₃O₂ cathode, markedly enhancing its cycling stability. Moreover, FEMC which possess a lower LUMO level than  EMC counterpart can form a robust and LiF-rich Solid Electrolyte Interphase (SEI). Through the synergistic stabilization of both cathode and anode interfaces, FEMC-a Film Forming Additive,  markedly enhances the cycling performance of NCM523 batteries.   3. Enhance flame retardant characteristics and boost overall battery safety   As a Solvent Additives in lithium-ion battery electrolytes, FEMC markedly improves flame retardancy. Gyeong-Jun Chung et al. demonstrated through self-extinguishing time (SET) tests and differential scanning calorimetry (DSC) measurements on cathode–electrolyte couples that FEMC enhances the non-flammability of NCM622 systems.  FEMC is a kind of Flame Retarding Additives, which can elevate thermal stability and strengthen overall battery safety.   Other fields   FEMC framework contains trifluoroethyl and carbonate moieties, which can endow it with high reactivity and selectivity in fluorinated fine-chemical synthesis. FEMC is a valuable fluorinated building block for the preparation of a wide range of high-value-added fluorinated specialty chemicals.   Technical challenges and optimization strategies for FEMC   Although FEMC has demonstrated remarkable advantages in lithium-ion electrolytes, its formulation still demands further optimization:   1. The –CF₃ group in the FEMC skeleton weakens Li⁺ solvation and lowers ionic conductivity. Consequently, FEMC content must be precisely controlled to strike a balance between flame-retardance and conductivity.   2. In neat FEMC-based electrolytes, Li⁺ readily coordinates with FEMC and further depresses the LUMO level and triggering continuous. This leads to irreversible decomposition of the electrolyte on the graphite interface with persistent gas generation.   Tuning the FEMC ratio and co-formulating with additional solvent or Electrolyte Additive are therefore active research directions for developing stable, high-voltage FEMC-based electrolytes.   FEMC of Cheerchem   Cheerchem Advanced Materials is driven by cutting-edge innovation and has created a best-in-class FEMC that makes us a trusted partner in lithium-ion electrolyte solutions.

Untreated light sources often suffer from three major pain points: light concentration, severe glare, and uneven brightness. For instance, exposed LED chips emit harsh point-like light, which can cause visual fatigue when used directly for lighting; without diffusion treatment, the backlight of LCD screens will show obvious light spots and dark areas. Therefore, it is necessary to use light diffusion materials to convert point light sources into linear or surface light sources, and achieve uniform light intensity distribution through beam shaping, so as to soften the light source and eliminate glare.   The key characteristic of light diffusion materials lies in balancing the dual properties of "light transmittance" and "haze". The main way to achieve this performance is to add Light Diffusing Agent to transparent polymer matrices such as PS, PC, and PMMA. The core of its working principle is "the deflection of light propagation direction caused by the difference in refractive index".   Light diffusing agents are mainly divided into inorganic and organic categories. Inorganic light diffusers are represented by silica and titanium dioxide; they achieve light scattering by virtue of their high refractive index, but have shortcomings such as irregular particle shapes, large particle size deviations, and low light transmittance. Organic light diffusers include acrylic resin microspheres and polystyrene microspheres, which have good dispersibility and low light transmittance loss but suffer from insufficient heat resistance.   The Cheerspearl series High Quality Spherical Silicone Resin developed by Cheerchem combines the advantages and makes up for the shortcomings of both categories, boasting excellent light diffusion performance and stability.   ● Excellent light diffusion performance With high sphericity and excellent surface regularity, it not only reduces the disordered loss of light caused by irregular particle morphology but also enables more uniform light scattering to improve diffusion efficiency, thereby achieving better light diffusion effects.   A moderate refractive index difference must be maintained between the Light Diffuser and the matrix resin: a sufficient difference is required to generate effective light refraction, while an excessively large difference must be avoided to prevent total reflection (which would significantly reduce transparency). The refractive index of spherical silicone resin is 1.43; compared with PMMA-based light diffusers, when achieving the same haze in PS diffuser panels, the addition amount of Spherical Silicone Resin can be significantly reduced.   In addition, it has a narrow particle size distribution and uniform particle size, which further ensures uniform light scattering and optimizes the light diffusion effect.     ● Stability Spherical Silicone Resin can withstand high temperatures above 400℃. During the processing process, it will not deform due to excessively high processing temperatures (which would otherwise affect the light diffusion effect); when used in high-temperature environments, it still maintains stable light diffusion performance. This ensures that products such as lamps will not experience issues like yellowing or black spots (which damage lighting effects) due to temperature, thereby extending the service life of products and reducing maintenance costs. Currently, the Cheerspearl series Silicone Powder from Cheerchem has been widely used in scenarios such as LED lighting covers, LCD light diffuser panels, and automotive lighting fixtures. It provides dual guarantees of "high-efficiency diffusion + stable durability" for various optical products.

Introduction to 1,3-Propenesultone   1,3-Propenesultone (PST) is an unsaturated cyclic sulfonate ester with the molecular formula C₃H₆O₃S and a molecular weight of 120.13. It has a melting point of 83-84 °C and a boiling point of 118 °C at 0.1 mmHg. First reported in the late 1950s, PST contains both a carbon–carbon double bond and a sulfonate ring, which endow it with a higher reduction potential than 1,3-propanesultone (1,3-PS). This allows PST to decompose preferentially on the electrode surface and form a stable Solid Electrolyte Interphase (SEI).[1] In 2002, Hibara and co-workers at Mitsui Chemicals first proposed PST as an Electrolyte Additive for lithium-ion batteries.[2] Because of its structural similarity to 1,3-PS and a comparable decomposition mechanism, PST is regarded as an alternative to 1,3-PS. The application of 1,3-Propenesultone in lithium-ion batteries   As a key Electrolyte Additive, 1,3-Propenesultone (PST) markedly enhances the overall electrochemical performance of lithium-ion batteries. The underlying mechanism lies in its ability to undergo preferential redox reactions on both the cathode and anode surfaces, thereby forming a stable and uniform Solid Electrolyte Interphase (SEI). The specific improvements are manifested in the following three aspects.   1. Suppresses gas generation and enhance high-temperature performance   K. J. Nelson and co-workers investigated the effect of PST in NCM111/graphite cell and found that batteries containing 2 % PST generated significantly less gas during high-temperature storage and cycling than the 2 % VC control group. PST is used as a High Temperature Battery Additive.  PST can improve the storage stability at 60 °C, suppresse voltage decay, and restrain impedance growth during storage.[3]   2. Enhance cathode stability   Bin Li et al.[4] demonstrated that 1,3-Propenesultone (PST) improves the stability of LiMn₂O₄ cathodes. During charge–discharge cycling, the presence of Mn³⁺ triggers the Jahn–Teller effect, destabilizing the structure, fracturing particles, and promoting severe Mn3+ dissolution, all of which degrade cycle life. Cells containing 5 % PST form a robust cathode-electrolyte interphase that suppresses Mn³⁺ leaching, thereby enhancing cathode stability and markedly improving cycling performance.   3. Compatible with high-capacity cathodes and  High Voltage Lithium Batteries   Lithium-rich oxide is one of the most promising cathodes that meet high energy density requirement for batteries of the future, but its phase transformation from layer to spinel structure caused by the lattice instability presents severe challenge to cycling stability and the actually accessible capacity. In a high-voltage Li-rich Mn-based system, Wenqiang Tu et al. found that 2 % PST enhances the stability of the Li-rich cathode, increases the initial discharge capacity, and markedly improves the cycling performance of lithium-ion batteries.[5]   Other fields   1,3-Propenesultone (PST) incorporates a carbon–carbon double bond, a five-membered ring, and a sulfonyl group within a single molecule. The high ring strain of the five-membered cycle and the strong electron-withdrawing effect of the sulfonyl moiety jointly endow PST with exceptional reactivity, making it a valuable intermediate in both agrochemical and pharmaceutical syntheses.[6]   References [1] Bo Tong, Ziyu Song, Huihai Wan, et al.

Current mainstream countermeasures: 1. Precise dosage control ; 2. Co-use with Low Impedance Additives to build a thin yet robust hybrid interphase; 3. Functional molecular design or solvation-structure tuning to further reduce charge-transfer resistance.   PST of Cheerchem   Cheerchem is committed to continuous technical innovation and process optimization, and has successfully developed a premium-grade PST product with the following core advantages: Ultra-high purity: consistently ≥ 99.5 %. Reliable quality: advanced manufacturing and rigorous QC guarantee excellent batch-to-batch consistency and long-term stability.

I. Introduction to the Physical Properties of TMSP Tris(trimethylsilyl) phosphate (TMSP) is a colorless transparent liquid, which has a density of 0.953 g/cm³, a refractive index of 1.4071 at room temperature, a boiling point of 228–229 °C at atmospheric pressure, and a flash point of 110.8 °C at atmospheric pressure. Its unique phosphorus-containing structure and trimethylsilyl groups endow TMSP with distinctive physicochemical properties and broad application prospects. II. Applications of TMSP 1. In the Field of Lithium-Ion Battery Electrolyte Technology Research on the application of TMSP in lithium-ion batteries was first reported in 2014. Since then, TMSP has attracted significant attention from both the academic and industrial sectors as an excellent film-forming additive. TMSP has a relatively low redox potential, enabling it to be oxidized and decomposed preferentially over solvents and form a dense, smooth cathode electrolyte interphase (CEI) film rich in elements such as C, O, P, and Si on the cathode surface. In the field of lithium-ion batteries, TMSP exhibits a variety of outstanding performances: (1) Improving initial coulombic efficiency and reducing impedance In the study by Guochun Yan et al. [1], it was found that in NCM523 batteries, TMSP can form a stable film in the early stage of cycling, while also reducing the impedance growth of the battery during long-term cycling. TMSP can improve the initial discharge efficiency of the battery and enhance its cycling performance. (2) Inhibiting self-discharge Xiaolin Liao et al. [2] discovered that adding 1 wt% TMSP to NCM111 batteries can inhibit the self-discharge phenomenon and improve the room-temperature cycling performance. (3) Enhancing high-rate performance A study by Haibo Rong et al. [3] showed that the addition of 1 wt% TMSP can improve the high-rate performance of batteries at room temperature. (4) Suppressing capacity fading Haibo Rong’s team [4] verified through experiments that TMSP can inhibit the dissolution of transition metals in lithium nickel manganese oxide batteries and their deposition on the anode. Additionally, it reduces battery capacity fading by suppressing side reactions of the electrodes. (5) Improving high-voltage cycling performance Fei Xu et al. [5] found that the addition of 1 wt% TMSP can enhance the high-voltage cycling performance of ternary lithium-ion batteries. 2. Other Fields TMSP is widely used as a catalyst in organic synthesis processes. It can serve as a cross-linking agent for polysilicate resins and organosilicon polymers, and is applied in the preparation of coatings, adhesives, and sealants. TMSP is also used as an organic synthesis reagent, acting as a catalyst for the reduction of ketones and allylation reactions. III. TMSP Products of Cheerchem Adhering to the concept of technological innovation and process optimization, Cheerchem has successfully developed high-performance TMSP products. The characteristics of our products are as follows: (1) High purity: The product purity is stably maintained above 99.9%; (2) Quality assurance: Relying on advanced production technology to ensure stable and reliable product quality; (3) Supply advantage: Sufficient production capacity and stable supply to provide long-term services for the lithium-ion battery industry; Ⅳ.

Chinese lithium companies are investing big to expand their global footprint in a race to secure material supplies for the production of new energy vehicle batteries. Ganfeng Lithium Co, located in Jiangxi province, announced in June to acquire a 50 percent stake in SPV Co in the Netherlands, whose subsidiary Lithium du Mali SA owns a spodumene project, namely Goulamina, in Mali, Africa. The company also signed a memorandum of understanding in May with Jujuy province in Argentina on building a lithium battery factory. In the same month, a Ganfeng's subsidiary in Shanghai announced to buy the London-listed mining company Bacanora Lithium for no more than 190 million pounds ($254 million). Bacanora Lithium's major asset is a lithium clay project called Sonora in Mexico. It is among the world's largest lithium projects with an estimated reserve of 8.82 million metric tons of lithium carbonate equivalents. In March, Ganfeng Lithium and its subsidiary in Qinghai province announced the acquisition of Ili Hongda, an investment and consulting company located in the Xinjiang Uygur autonomous region that partly owns a stake in a lithium project in Qaidam Basin. Ganfeng is not the only lithium company actively expanding their global footprint. Companies including Eve Energy Co Ltd, Gotion High-Tech and Anshan Heavy Duty Mining Machinery Co Ltd were also reported to have acquired lithium mining projects inside and outside the country. Aside from acquiring lithium mining projects, the companies are also ramping up imports of the metal. A report by S&P Global Platts, a market information provider on energy, showed that China's lithium imports remained elevated amid tight domestic supplies, and the trend is expected to continue in the coming months to fill the gaps in supply caused by the surging NEVs market. Lithium carbonate imports jumped 193.5 percent month-on-month to 10,476 tons in October, according to Customs data. Lin Boqiang, head of the China Institute for Studies in Energy Policy at Xiamen University, said the investment frenzy in the lithium mining sector was due to the expansion of production lines of lithium-ion batteries for the booming NEV market driven by China's decarbonization goals, as well as surging prices of raw materials. Chinese battery makers are stepping up efforts to boost output. Battery giant Contemporary Amperex Technology Co Ltd (CATL) announced in November it will invest no more than 8 billion yuan ($1.25 billion) and 7 billion yuan in battery manufacturing projects in Fujian and Guizhou provinces, respectively. A report from a news website Jiemian said that CATL has been expanding battery production since December in eight manufacturing plants for batteries across the world. Another battery giant, Guangdong province-based Eve Energy Co Ltd announced that its subsidiary in Hubei province had planned to invest 6.2 billion yuan in battery manufacturing projects in Jingmen, Hubei province, in November. This follows an earlier round of investment of 2.45 billion yuan in multiple lithium battery projects in the same city in July. Data from the China Automotive Battery Innovation Alliance showed that production of batteries that power NEVs has reached an accumulated 159.8 gigawatt-hours in the first 10 months, up 250 percent year-on-year. The total number of batteries installed in NEVs amounted to 107.5 GWh, up 168.1 percent year-on-year. Data from the China Association of Automobile Manufacturers showed that NEV production this year is on the brink of breaking last year's record, with output in the first 10 months reaching 2.57 million units, up 133.2 percent year-on-year. "Lithium companies' investment frenzy was also spurred by surging prices of raw materials, which was a result of the overall price increase of commodities, and also a result of tight supplies and growing demand from downstream battery and NEV makers," Lin said. The S&P Global Platts report showed that prices of lithium carbonate have risen 238.3 percent since the beginning of this year to Nov 19, and hydroxide prices jumped 252.8 percent in the same period.

For the second time in a week, Stellantis has announced plans to produce electric vehicle batteries for its North American assembly plants in a joint venture with a South Korean company. This time, the company is Samsung SDI, according to a news release early Friday. That followed a similar announcement Monday with LG Energy Solution. The automaker, which counts Jeep, Ram, Chrysler and Dodge among its brands, said it's reviewing the location of the future lithium-ion battery plant, just as it did with its LG announcement. Production is targeted for 2025; the LG plant is supposed to start production in 2024. The two announcements in such a short period highlight the rapid push in the auto industry toward electrification. Stellantis announced in July plans for $35 billion (30 billion euros) in electrification and related software investments through 2025 with more than 40% of sales in the United States and 70% of sales in Europe to be low-emission vehicles by 2030. The company has said it will build an electric Dodge muscle car and Ram 1500 pickup in 2024.
