Abstract

The embodiment of the invention provides a battery box and an energy storage battery, and relates to the technical field of batteries. The battery box comprises a shell and a battery arranged in the shell, the shell and the battery are bonded through a heat-conducting structural adhesive, the heat conductivity coefficient of the heat-conducting structural adhesive is lambda, the unit is W/mK, the water absorption rate of the heat-conducting structural adhesive is omega, the unit is%, and the heat conductivity coefficient lambda and the water absorption rate omega meet the relational expression that lambda/omega is larger than or equal to 0.3 and smaller than or equal to 40. By adjusting the components in the heat-conducting structural adhesive, the balance between the water absorbability and the heat-conducting property of the heat-conducting structural adhesive can be improved. The battery box adopts the heat-conducting structural adhesive to fix the battery, the assembly is convenient, the number of assembly parts is reduced, and the heat-conducting property and the insulating and pressure-resistant properties of the heat-conducting structural adhesive can be optimized.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery box and an energy storage battery. Background technique [0002] With the vigorous development of the new energy industry, the design of the battery box has gradually attracted widespread attention and has become the focus of research in the field of new energy. [0003] In the prior art, the battery box includes a box body and a battery, and the battery is arranged in the box body. In order to reliably position the battery in the box body and realize effective heat dissipation, the battery can be fixed on the box body with heat-conducting structural glue, which makes assembly more convenient. It is also beneficial to improve the overall energy density of the battery box. However, it has been found in practical applications that the heat-conducting structural adhesive will absorb moisture in the environment during the actual operation of the battery box, which will r...
