Abstract: Disclosed is a power storage unit which can safely operate over a wide temperature range. The power storage unit includes: a power storage device; a heater for heating the power storage device; a temperature sensor for sensing the temperature of the power storage device; and a control circuit configured to inhibit charge of the power storage device when its temperature is lower than a first temperature or higher than a second temperature. The first temperature is exemplified by a temperature which allows the formation of a dendrite over a negative electrode of the power storage device, whereas the second temperature is exemplified by a temperature which causes decomposition of a passivating film formed over a surface of a negative electrode active material.

Abstract: 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.
