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: A highly portable and highly browsable light-emitting device is provided. A light-emitting device that is less likely to be broken is provided. The light-emitting device has a strip-like region having high flexibility and a strip-like region having low flexibility that are arranged alternately. In the region having high flexibility, a light-emitting panel and a plurality of spacers overlap with each other. In the region having low flexibility, the light-emitting panel and a support overlap with each other. When the region having high flexibility is bent, the angle between normals of facing planes of the two adjacent spacers changes according to the bending of the light-emitting panel; thus, a neutral plane can be formed in the light-emitting panel or in the vicinity of the light-emitting panel.
