ELECTRODE FOR LITHIUM ION SECONDARY BATTERY AND METHOD OF MANUFACTURING THE SAME

Abstract:

To provide an electrode for a lithium ion secondary battery in which the binding strength of an electrode active material can be increased without increasing the amount of a binder, and a desirable energy density of the lithium ion secondary battery can be achieved, and a method of manufacturing the same. An electrode for a lithium ion secondary battery includes an electrode active material, a dendritic polymer, and a binder. The dendritic polymer is chemically bonded to a surface of the electrode active material. The dendritic polymer and the binder are chemically bonded to each other.
