Honeycomb structure current collector for electrode of lithium ion secondary battery, electrode for lithium ion secondary battery, and method for producing honeycomb structure current collector for electrode of lithium ion secondary battery

摘要

PROBLEM TO BE SOLVED: To provide a collector and an electrode which enables large capacity, without damaging a light-weight propery of a lithium ion secondary cell. SOLUTION: A honeycomb-structure collector 10 for an electrode lithium ion secondary cell formed by coating a titanium nitride film 15 to a partition surface of a cell 12, including a outer surface of a carbonaceous honeycomb structure 11, an active material 21 for a positive electrode or a negative electrode being charged in the cell.
