Electrolyte for non-aqueous batteries and secondary battery using the same |
摘要 |
The non-aqueous electrolyte-containing secondary battery of the present invention uses a non-aqueous electrolyte including at least one phosphoric ester derivative expressed by Formula (1): (R1aO)(R2aO)P(O)X and by Formula (2): R(1bO)P(O)X2, wherein R1a, R2a, and R1b independently denote aliphatic hydrocarbon groups having 1 to 12 carbon atoms and X denotes a halogen atom. This arrangement improves the high-temperature storage characteristics after charging and the charge-discharge cycle characteristics of the secondary battery.
