摘要： 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 sufficiently secure electron conductivity between a foam metal body and an electrode active material in an electrode for lithium ion secondary batteries which establish a foam metal body as the collector, reduce the resistance of a lithium ion secondary batter, and improve the durability.
A carbon layer consisting of carbon material is disposed on a surface of a foam porous body consisting of metal, and used as a collector. More specifically, an electrode for lithium ion secondary batteries includes a collector, and an electrode mixture filled into the collector, in which the collector is made to have a carbon layer consisting of carbon material on a surface of a foam porous body consisting of metal.

摘要： 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.
