Abstract
Disclosed are an additive for improving charge/discharge characteristics of a lithium-ion cell, a nonaqueous electrolytic solution containing the additive, and a lithium-ion cell using the additive and/or the nonaqueous electrolytic solution. The additive serves as a solvent for a fluorine resin, such as poly(vinylidene fluoride), which is incorporated as an adhesive in a positive electrode containing a lithium-transition metal oxide capable of absorbing and releasing lithium and a negative electrode containing a carbon material capable of absorbing and releasing lithium. The additive comprises three compounds selected, respectively, from a 2-pyrrolidinone compound group, a cyclic alkyl compound group, and a cyclic pentanone compound group.
