WO WO2026156614A1
A battery apparatus and an electric apparatus. The battery apparatus comprises: a case; a battery cell assembly comprising: casing assemblies each having an accommodating cavity and comprising a partition plate provided in the corresponding accommodating cavity, wherein the partition plate partitions the accommodating cavity into a first chamber and a second chamber which are communicated with each other; and pouch battery cells provided in the first chambers and bonded to the case, wherein the second chambers are configured to accommodate a medium discharged from the first chambers. In the technical solution, when thermal runaway occurs in a certain pouch battery cell, a discharged high-temperature and high-pressure medium can enter the second chambers, thereby reducing the risk of accumulation in the first chambers and further reducing the possibility of thermal propagation; and the casing assemblies can further reduce the range of movement and deformation of each pouch battery cell, and improve stability of positions of the pouch battery cells within the battery cell assembly, thereby reducing the probability of short circuit or electrical leakage caused by movement of the pouch battery cells.
