Abstract
PURPOSE: To realize nonaqueous electrolyte for lithium secondary battery for prolonging a battery lifetime of a lithium secondary battery by including a special pyrrole derivatives.
CONSTITUTION: At least one kind of pyrrole derivatives having methyl group at one of positions of first, second, third, fourth and fifth is included as a component of the nonaqueous electrolyte. About 0.1-5 volume % of that pyrrole derivatives is added to an ordinary solvent which compound of one kind or more than two kinds of solvent. A lithium secondary battery using the described non-aqueous electrolyte and that pyrrole derivatives restrict the reactionability of the nonaqueous electrolyte with electrodeposited lithium to improve cycle characteristic of a negative electrode. Consequently, lifetime of a battery is improved.
