Rechargeable lithium electrochemical cell |
摘要 |
The present invention concerns a rechargeable lithium electrochemical cell comprising an anode containing a carbon-containing material with a degree of crystallinity which is greater than 0.8 and an electrolyte comprising a lithium salt and a mixture of at least two aprotic organic solvents, of which the first solvent has a high dielectric constant and the second solvent has low viscosity. The electrolyte further contains a soluble compound of the same type as at least one of said solvents and contains at least one unsaturated bond, and which can be reduced at the anode at a potential of more than 1 volt with respect to lithium to form a passivation layer.
