Abstract
Official abstract text for this publication.
The present invention provides a lithium-ion secondary battery with excellent high-temperature storage characteristics. The lithium-ion secondary battery provided by the present invention has positive and negative electrodes capable of absorbing and desorbing lithium ions, and an electrolyte solution containing a lithium salt as a supporting salt in an organic solvent. The nonaqueous electrolyte contains not only the lithium salt, but also at least one type of dicarboxylic acid as additive A; and at least one type of additive selected from vinylene carbonate, vinylethylene carbonate, ethylene sulfite, and fluoroethylene carbonate as additive B.
First claim
Opening claim text (preview).
The invention claimed is: 1. A lithium-ion secondary battery comprising: positive and negative electrodes capable of absorbing and desorbing lithium ions, the negative electrode comprising a particulate carbon material as a negative electrode active material; and a nonaqueous electrolyte containing a lithium salt as a supporting salt in an organic solvent, wherein the nonaqueous electrolyte further contains: at least one dicarboxylic acid as additive A; and at least one ty…
