摘要： An object of one embodiment of the present invention is to provide a secondary battery in which deterioration of charge-discharge cycle characteristics is suppressed, to suppress generation of defects caused by expansion and contraction of an active material in a negative electrode, or to prevent deterioration caused by deformation of a secondary battery. To prevent deterioration, a material that can be alloyed with lithium and fluidified easily is used for a negative electrode. To hold a negative electrode active material over a surface of a current collector, a covering layer that covers the negative electrode active material is provided. Furthermore, a portion where the current collector and the negative electrode active material are in contact with each other is alloyed. In other words, an alloy that is in contact with both the current collector and the negative electrode active material is provided in the negative electrode.

摘要： A decrease in the capacity of a power storage device is inhibited by adjusting or reducing imbalance in the amount of inserted and extracted carrier ions between positive and negative electrodes, which is caused by decomposition of an electrolyte solution of the negative electrode. Further, the capacity of the power storage device can be restored. Furthermore, impurities in the electrolyte solution can be decomposed with the use of the third electrode. A power storage device including positive and negative electrodes, an electrolyte, and a third electrode is provided. The third electrode has an adequate electrostatic capacitance.
