Non-aqueous electrolyte and non-aqueous electrolyte battery

Abstract

A nonaqueous electrolyte includes: a solvent; an electrolyte salt; an aromatic compound represented by the following formula (1); and a polyoxometalate and / or a polyoxometalate compound wherein each of R1 to R6 independently represents a hydrogen group, a halogen group, an aliphatic alkyl group, an alicyclic alkyl group, a phenyl group or an alkoxy group; at least one of R1 to R6 is a halogen group, an aliphatic alkyl group, an alicyclic alkyl group, a phenyl group or an alkoxy group; a part or all of hydrogens of R1 to R6 may be substituted with a halogen; and at least a part of R1 to R6 may be bonded to each other to form a ring.

Description

Technical field [0001] The invention relates to a non-aqueous electrolyte and a non-aqueous electrolyte battery. More specifically, the present invention relates to a non-aqueous electrolyte containing an organic solvent and an electrolyte salt and a non-aqueous electrolyte battery using the non-aqueous electrolyte. Background technique [0002] In recent years, portable electronic devices such as video cameras, mobile phones, and laptop personal computers have become widespread, and there is a strong demand for miniaturization, light weight, and long life. As a result, the development of batteries as power sources for portable electronic appliances, especially secondary batteries that are lightweight and capable of obtaining high energy density, has been promoted. [0003] In particular, secondary batteries (so-called lithium ion secondary batteries) that utilize lithium insertion and extraction to perform charge / discharge reactions have great prospects because they can achieve h...
