摘要:
A non-aqueous electrolyte secondary battery is produced using a non-aqueous electrolyte including: a non-aqueous solvent that primarily contains a solvent mixture of ethylene carbonate and propylene carbonate and includes a fluorine-substituted ether having a divalent group represented by a formula: —CFX—CH(CH3)—O—, where X is a hydrogen atom or fluorine atom, in a molecule thereof; and a lithium salt that is dissolved in the non-aqueous solvent. The non-aqueous electrolyte has favorable wettability towards a polyolefin separator, and improves the cycle characteristics and the load characteristics of the non-aqueous electrolyte secondary battery.
