ELECTRODE FOR LITHIUM ION SECONDARY BATTERIES AND LITHIUM ION SECONDARY BATTERY

Abstract:

Provided are an electrode for lithium ion secondary batteries which is an electrode for obtaining a lithium ion secondary batteries having high energy density with foam metal as the collector, and further being able to improve durability and input/output characteristics (output density), as well as a lithium ion secondary battery made using this electrode for lithium ion secondary batteries. The electrode layer of the electrode for lithium ion secondary batteries using a collector consisting of foam metal is configured by dividing into a plurality of electrode divided parts, whereby the migration distance of electrons and migration distance of ions in each of the electrode divided parts is shortened.
