Title:
蓄電装置の作製方法
Document Type and Number:
Japanese Patent JP5780852
Kind Code:
B2
Abstract:
It is an object to improve performance of a power storage device, such as cycle characteristics. A power storage device includes a current collector and a crystalline semiconductor layer including a whisker, which is formed on and in close contact with the current collector. Separation of the crystalline semiconductor layer is suppressed by an increase of adhesion, whereby cycle characteristics in which a specific capacity of a tenth cycle number with respect to a first cycle number is greater than or equal to 90% is realized. In addition, cycle characteristics in which a specific capacity of a hundredth cycle number with respect to a first cycle number is greater than or equal to 70% is realized.
