These Thai-Institute, Si, and Sibaoluo fluids have low volatility, while still: 2 ▲ 于Compared with known dissimilar battery performance in the art, it still retains the excellent B using graphite-based negative materials. Background 2 ::: Now the world is being densely developed to provide new-generation batteries. Regardless of the explicit design What are the methods? They are all… .. There are electrolytes containing sub-types and aprotic liquids (here referred to as electrolyte solvents) that provide a physical medium that allows ions to pass through. Commercial ion batteries—showing a high open circuit in general Voltage, 3.8 volts. This means that the charging voltage will be between 6 volts and about 4.2 volts <voltage 'and the temporary voltage will be even higher. Secondary lithium-ion batteries can be used not only in battery components The voltage to which it is exposed is generally high, and the battery components of lithium-ion batteries must withstand repeated exposure to these highly oxidizing conditions in countless charge / discharge cycles, which is different from the ㈣ metal battery in the art. The components of the Intellectual Property Bureau's consumer cooperatives must print the individual components of the Fengzi battery that can withstand the very high levels of electrochemical oxidation and reduction potential presented by repeated exposure to these types of dust. Many of the well-known electrolyte solvents for other types of batteries are not lithium-only. The use of ion batteries shows the necessary stability. In the art, there is no general solution for selecting such electrolyte solvents that can show the necessary stability. Except for the ore of trial and error, in practice, this point will be used in lithium ion batteries. The choice of electrolyte solvents used in the art is limited to acyclic and cyclic organic carbonates, and is mainly based on the Chinese paper standard (CNS) A4 (210 X 297 mm) for the paper size. 501301 A7 _B7__ 5. Description of the invention (2) Dimethyl carbonate (DMC), diethyl carbonate (DEC), ethyl methyl carbonate (EMC), propylene carbonate (PC), and ethylene carbonate (EC), and -unit esters such as methyl acetate (MA), ethyl acetate (EA), methyl formate (MF), methyl ethyl propionate (MP), ethyl propionate (EP), --- Butyric acid vinegar (GBL), as described in B. A. Johnson, and RE White, "Characterization of Commercially Available Li-ion Batteries", Journal of Power Sources , 70, 48-54, (1998). These electrolyte solvents are most often used in combination with cyclic organic carbonates, usually EC or PC, and acyclic carbonates, usually DMC, DEC, or EMC, such as Revealed in U.S. Patent No. 5,525,443 issued to Matsushita. These combinations have been found in practice to achieve excellent combinations of desired properties, such as high ion conductivity and relatively low volatility over a wide temperature range, while achieving excellent life and performance in lithium-ion batteries. State-of-the-art technology also clearly explains the "Electrolytes for Rechargeable Lithium Batteries" by M. Morita, M. Ishikawa, and Y. Matsuda, Lithium-Ion, Surface Ion Batteries, and Performance Batteries, Fundamentals and Performance), Chapter 7, edited by M. Wakihara and O. Yamamoto, Wiley VCH, 1998. There are also a large number of patented techniques that disclose the electrolyte solvents used in clock ion batteries. The disclosed electrolyte solvents suitable for bell ion batteries can be roughly classified into three categories: (1) halogen-substituted organic carbonates such as 2-fluoroethylene carbonate, and (2) organic carbonates and acyclic or cyclic esters. Depleted mixtures, such as EC + DMC + methyl formate, and (3) unsaturated organic acids such as ethyl carbonate.
