Abstract

This invention provides a lithium secondary battery comprising a positive electrode, a negative electrode, and a non-aqueous electrolyte. On the negative electrode surface, there is present a cyclic siloxane and/or a reaction product thereof. The cyclic siloxane is a cyclic siloxane having at least one side chain comprising a dimethylsiloxy group (a siloxy side chain-containing cyclic siloxane).
