Abstract

Embodiments of the present application provide a battery and a power consumption device. The battery includes a battery cell group and a thermal management device. The battery cell group includes a plurality of battery cells. The thermal management device is used to adjust the temperature of the battery cell group. Here, at least two surfaces of the battery cells are thermally conductively connected to the thermal management device. Embodiments of the present application can increase the heat exchange area of the battery cells, improve the thermal management efficiency of the thermal management device for the battery cells, further meet the cooling requirements for the battery under operating conditions of a larger current or faster charging, and meet the heating requirements for the battery in a lower temperature environment, thereby improving the safety and service life of the battery.
