NEGATIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
摘要:
This negative electrode for a nonaqueous electrolyte secondary battery is configured such that a negative electrode mixture layer has: a first layer that is formed on a negative electrode collector and that contains a first carbonaceous active material, a Si-based active material, a polyacrylic acid or a salt thereof, and a fibrous carbon; and a second layer that is formed on the first layer and that contains a second carbonaceous active material which has a tap density higher than that of the first carbonaceous active material.
