Battery shell and battery module

The invention relates to the technical field of battery production, and discloses a battery shell and a battery module. The battery shell comprises a shell body, a central accommodating cavity for accommodating a single battery is arranged in the shell body, a buffer chamber is also arranged on the shell body, the buffer chamber is annularly arranged outside the central accommodating cavity, and a buffer piece is arranged in the buffer chamber. When the battery module is impacted, dropped and extruded, the buffer piece can buffer the impact force, and the phenomena of deformation, fire and the like of the single batteries in the central accommodating cavity due to the violent impact force are prevented, so that the safety of the battery module is ensured. 本发明涉及电池生产技术领域，公开一种电池外壳及电池模组。该电池外壳包括壳体，壳体内设置有用于容置单体电池的中心容置腔，壳体上还设置有缓冲腔室，缓冲腔室环设于中心容置腔外，缓冲腔室中设置有缓冲件。当该电池模组受到冲击、跌落、挤压时，缓冲件能够对该撞击力进行缓冲，防止中心容置腔中的单体电池受到剧烈的撞击力，导致其发生变形、失火等现象，从而保证该电池模组的安全性。
