Abstract
A positive electrode active material composition, a positive electrode plate, a battery, and an electrical apparatus are provided. The composition includes a first positive electrode active material and a second positive electrode active material having a crystal form different from that of the first. The first active material comprises a phosphate. The particle size distribution curve of the composition exhibits at least two volume distribution peaks. The peak with the highest intensity is defined as the first peak, with a corresponding volume-based particle size Dv1. The peak with the second highest intensity is defined as the second peak, with particle size Dv2. The relative difference in particle sizes satisfies the condition 0<|Dv1−Dv2|/Dv1≤50. This dual-peak structure improves the electrochemical performance of the electrode.
