Abstract

A positive electrode sheet and a preparation method therefor, a battery, and an electric device. The positive electrode sheet comprises: a positive electrode active material layer, the positive electrode active material layer comprising a positive electrode active material; and a capacity compensation layer, the capacity compensation layer being provided on at least one side of the positive electrode active material layer, and the capacity compensation layer comprising a capacity compensation agent and an additive. Therefore, the probability that the additive reacts with residual alkali is increased, the content of residual alkali on the surface of the capacity compensation agent is reduced, the capacity compensation effect is improved, and the cycle capacity retention rate of the battery is improved.
