Abstract
Lithium replenishing spaces are disposed on a current collection structure, such that the lithium replenishing spaces communicate with an active layer on one side; and the battery is replenished with lithium by using lithium replenishing agents in the lithium replenishing spaces to offset an irreversible lithium consumption in a cycle process, so as to increase the total capacity and the energy density of the battery. According to the present application, due to average weights Mof corresponding active materials in different distribution regions on the active layer, a sum V0 of internal volumes of lithium replenishing spaces corresponding to each of the distribution regions is controlled in a positively correlated manner based on a change in the average weights of the active materials in the different distribution regions.
