Title:
POSITIVE ELECTRODE COMPOSITION, POSITIVE ELECTRODE, AND BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/270361
Kind Code:
A1
Abstract:
This positive electrode composition contains carbon black, carbon nanotubes, an active material, and a binder. The carbon black has a BET specific surface area of 100-400 m2/g, and a crystallite size (Lc) of 15-26 Å. The carbon nanotubes have an average diameter of 5-15 nm. The ratio (average diameter/BET specific surface area) of the average diameter with respect to the BET specific surface area of the carbon nanotubes is 0.01-0.068 nm/(m2/g).
