Abstract
A hybrid positive electrode active material includes a first positive electrode active powder and a second positive electrode active powder. Each particle of the second positive electrode active powder contacts a plurality of particles of the first positive electrode active material. Characteristically, the average particle size of the first positive electrode active powder is smaller than the average particle size of the second positive electrode active powder.
