BATTERY ASSEMBLY AND ELECTRIC DEVICE

The present application provides a battery assembly and an electric device. The battery assembly comprises first batteries and second batteries; the first batteries expand during charging and contract during discharging; and the second batteries contract during charging and expand during discharging. The battery assembly can effectively solve the problem of capacity attenuation caused by excessive volume change or excessive pressure change of batteries during charging and discharging, and can be used for providing an electric device having long battery life and continuous and stable battery life. La présente demande concerne un ensemble batterie et un dispositif électrique. L'ensemble batterie comprend des premières batteries et des secondes batteries ; les premières batteries se dilatent pendant la charge et se contractent pendant la décharge ; et les secondes batteries se contractent pendant la charge et se dilatent pendant la décharge. L'ensemble batterie peut résoudre efficacement le problème d'atténuatio
