Abstract
Disclosed is a non-aqueous electrolytic solution secondary cell having a negative electrode containing a carbonaceous material capable of occluding and liberating lithium, a positive electrode, a non-aqueous electrolytic solution which includes a solute and an organic solvent, and a separator; wherein the organic solvent contains at least one of compounds selected from those expressed by the formulae (I) and (II) below (in which &phgr; represents a phenyl group optionally having an alkyl group; and R represents any one of a hydrogen atom, C alkyl groups and a phenyl group optionally having an alkyl group). Such non-aqueous electrolytic solution secondary cell of the present invention is successful in suppressing decomposition of the electrolytic solution, and achieving a high capacity and excellent cycle characteristics.
