LITHIUM BATTERY WHICH IS PROTECTED IN CASE OF INAPPROPRIATE USE

摘要

A lithium battery comprising at least one positive electrode containing a material whose lithium insertion and deinsertion potential is lower than or equal to 3.5 Volts in relation to the Li⁺/Li couple, a negative electrode and a non-aqueous electrolyte disposed between the positive and negative electrodes. The electrolyte comprises at least one lithium salt which is dissolved in an aprotic organic solvent wherein a polymerizable additive is added, said additive being selected from among carbazol and the derivatives thereof and being used to prevent the battery from operating as soon as the voltage at the terminal connections of the battery exceeds a value resulting in polymerization of the additive.
