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.

摘要： A secondary battery to be provided includes an electrode including silicon or a silicon compound, and the electrode includes, for example, a current collector formed using metal and a silicon film as an active material provided over the current collector. The hydrogen concentration in the silicon film of the electrode may be higher than or equal to 1.0×1018 cm−3 and lower than or equal to 1.0×1021 cm−3. Such a silicon film is formed over a current collector by a plasma CVD method or the like for example, and hydrogen is contained as little as possible in the silicon film, which is preferable. In order to contain hydrogen as little as possible in the silicon film, the silicon film may be formed over the current collector under a high temperature environment.
