HIGH-CAPACITY BATTERY ASSEMBLY, REPAIR MECHANISM, AND REPAIR METHOD FOR HIGH-CAPACITY BATTERY ASSEMBLY

The present invention relates to the field of batteries, and in particular to a high-capacity battery assembly, a repair mechanism, and a repair method for the high-capacity battery assembly, so as to prolong the service lives of high-capacity batteries while solving the problem of having a difficulty in assembling shared pipeline assemblies of existing high-capacity batteries. The high-capacity battery assembly includes a high-capacity battery and a repair mechanism. The high-capacity battery includes a housing and battery cells arranged in the housing; the housing is provided with an electrolyte region of the inner cavity of each battery cell; an avoidance hole capable of enabling an electrode terminal of each battery cell to extend out is formed on a housing top plate; the electrode terminal of each battery cell extends out from the avoidance hole on the housing top plate, and a region of the housing corresponding to the avoidance hole is fixed and sealed with a shell of the battery cell; and the repair mechanism is connected with the high-capacity battery, and is configured for repairing the high-capacity battery having an attenuated capacity or inhibiting the attenuation speed of the high-capacity battery, so as to improve the performance of the high-capacity battery and prolong the cycle life of the high-capacity battery.
