Abstract
A battery shell, a battery cell and a large-capacity battery, which mainly solve the problem of poor performance of existing large-capacity batteries. The battery shell is provided with a first through hole and is also provided with a pipeline covering the first through hole and extending along a thickness direction of the battery shell, the pipeline is provided with a second through hole on a pipe body, and the first through hole communicates with the second through hole. An electrolyte sharing channel of a large-capacity battery is formed through the pipeline, and battery cells in the large-capacity battery may be in a unified electrolyte environment, thereby improving the performance of the large-capacity battery.
