Title:
ELECTRODE FOR LITHIUM SECONDARY BATTERIES, LITHIUM SECONDARY BATTERY, AND METHOD FOR PRODUCING ELECTRODE FOR LITHIUM SECONDARY BATTERIES
Document Type and Number:
WIPO Patent Application WO/2013/005739
Kind Code:
A1
Abstract:
Provided are: an electrode for lithium secondary batteries, which enables high-rate charging and discharging and is capable of maintaining high battery capacity retention rate even under large charge/discharge current conditions; a lithium secondary battery; and a method for producing an electrode for lithium secondary batteries. Adopted is an electrode for lithium secondary batteries, which comprises a metal foil, a coating layer that is provided on the surface of the metal foil and an electrode mixture that is laminated on the surface of the coating layer, and which is characterized in that: the coating layer contains a binder and conductive particles; and the electrode mixture contains an electrode active material and a conductive assistant that has a composition ratio in the electrode mixture of 0-1.4% by mass.
