ELECTRODE FOR LITHIUM ION SECONDARY BATTERIES AND LITHIUM ION SECONDARY BATTERY

Abstract:

To provide an electrode for lithium ion secondary batteries, and a lithium ion secondary battery made using this electrode for lithium ion secondary batteries, which can suppress an increase in electron resistance of a current collector area, and improve heat dissipation, in an electrode for lithium ion secondary batteries establishing a foam metal body as the collector. In the electrode for lithium ion secondary batteries made using a foam porous body consisting of metal as a current collector, the electrode shape is rectangular, and a current collector region is made to span at least two adjacent sides.
