摘要: 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.

摘要: An electrode and a power storage device each of which achieves better charge-discharge cycle characteristics and is less likely to deteriorate owing to separation of an active material, or the like are manufactured. As the electrode for the power storage device, an electrode including a current collector and an active material layer that is over the current collector and includes a particle containing niobium oxide and a granular active material is used, whereby the charge-discharge cycle characteristics of the power storage device can be improved. Moreover, contact between the granular active material and the particle containing niobium oxide makes the granular active material physically fixed; accordingly, deterioration due to expansion and contraction of the active material which occur along with charge and discharge of the power storage device, such as powdering of the active material layer or its separation from the current collector, can be suppressed.
