Abstract
An electrochemical apparatus includes a positive electrode plate, the positive electrode plate includes a positive electrode active material layer, the positive electrode active material layer includes a positive electrode active material, the positive electrode active material includes a manganese-containing material, and a mass ratio Y of the manganese-containing material to the positive electrode active material ranges from 0.4 to 1. Through control of the mass ratio Y of the manganese-containing material to the positive electrode active material in the positive electrode active material layer, Mn dissolution out of the positive electrode active material layer can be effectively controlled.
