POWER STORAGE DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To reduce the weight of a power storage device.SOLUTION: A metal sheet as an anode collector is peeled, and a new anode collector is formed. For example, after formation of silicon as an anode active material layer on a titanium sheet, the titanium sheet can be peeled through a heating process. Thereafter, a new anode collector having a film thickness of 10 nm to 1 μm inclusive is formed, thereby achieving weight reduction of a power storage device.
