ELECTRODE FOR BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a means capable of improving output characteristics while minimizing deterioration of capacity per volume accompanying the increase in the amount of use of a conductive assistant in a lithium ion secondary battery.

SOLUTION: The electrode for the battery includes a current collector and an active material layer formed on the current collector which includes an active material that has an average particle size exceeding 1 μm and 5 μm or less and a BET specific surface area of 1-5 m2/g and a conductive assistant of which content is 3-50 wt.% against 100 wt.% of the active material.
