CATHODE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a cathode for a lithium secondary battery with excellent high-rate discharge characteristics, and a lithium secondary battery using the cathode.

SOLUTION: The cathode for the lithium secondary battery is obtained by arranging a mixture layer containing silicon powder as an active material and a binder on the surface of a collector, of which a mixture layer resistance value after charging and discharging as defined in formula 1 is 5.0×1011Ω/m or less.
