ADDITIVES FOR IMPROVING THE REVERSIBILITY OF A CARBON ELECTRODE OF A LITHIUM ION SECONDARY ELECTROCHEMICAL GENERATOR |
摘要 |
The invention relates to additives to improve the reversibility of a carbon electrode of a lithium ion secondary electrochemical generator. These additives are composed of cyclic or non-cyclic alpha-halogenated esters such as alpha-bromo-gamma-butyrolactone or methyl chloroformiate. They may be added to the electrolyte at a rate of 0.5 to 3% by volume or adsorbed on the carbon electrode to form a passivation film on said electrode during the first use of the generator. |
