Abstract: This application discloses a battery box, including a battery case and a plurality of batteries accommodated in the battery case. The batteries are bonded to an inner wall of the battery case by using an adhesive, a coefficient of thermal expansion of the adhesive is α in units of ppm/° C., a coefficient of thermal conductivity of the adhesive is β in units of W/mK, and a ratio of α and β meet a relation of 15≤α/β≤80. In the battery box in this application, the battery case and the plurality of batteries accommodated in the battery case are bonded by using the adhesive. When the coefficient of thermal conductivity of the adhesive matches the coefficient of thermal expansion, heat conduction requirements of the battery box can be satisfied, and the adhesive can also be prevented from cracking or peeling off under heat stress due to alternating temperatures during use of the battery box, thereby improving safety performance of the battery box.
