Title:
BATTERY ELECTROLYTIC SOLUTION AND LITHIUM ION BATTERY
Document Type and Number:
WIPO Patent Application WO/2020/246501
Kind Code:
A1
Abstract:
Provided is a battery electrolytic solution in which a nanocarbon material is highly dispersed. The battery electrolytic solution contains: a dispersion medium; an electrolyte dissolved in the dispersion medium; and a nanocarbon material dispersed with an average dispersion particle size of 500 nm or less in the dispersion medium. The battery electrolytic solution preferably contains the nanocarbon material in an amount of 10-100000 mass ppm. It is preferable to use, as the nanocarbon material, at least one selected from the group consisting of nanodiamond, fullerene, graphene, graphene oxide, nanographite, carbon nanotube, carbon nanofilament, onion-like carbon, diamond-like carbon, amorphous carbon, carbon black, carbon nanohorn, and carbon nanocoil.
