NON-AQUEOUS SECONDARY BATTERY HAVING A BLENDED CATHODE ACTIVE MATERIAL

摘要

PURPOSE: An electrochemical active material has high capacity and/or increased recharging cycles. CONSTITUTION: An electrochemical active material includes two groups of mixtures of particles. The two groups are compounds represented by chemical formula 1: Li_xH_yV_3O_8 and compound represented by chemical formula 2: Li_xM_yPO_4, where M is one or more transition metals which includes at least one metal to conduct oxidation in a state of high valance. In order to obtain a synergistic effect, the content ratio of particles in chemical formula 1 to particles in chemical formula 2 is 5:95 wt% - 95:5 wt%. [Reference numerals] (AA) Synergistic effect
