Electrode mix for secondary battery, electrode for all-solid-state secondary battery, and all-solid-state secondary battery

Abstract

Provided is an electrode composite material for a secondary battery that can satisfy both the electronic conductivity and the ionic conductivity at a high level and thus effectively increase the battery characteristics. An electrode composite material for a secondary battery contains a positive-electrode active material and a conductive agent, the positive-electrode active material containing: (i) at least one transition metal element selected from the group consisting of Cr, Fe, Mn, Co, Ni, Ti, and Nb; (ii) at least one element selected from the group consisting of P, Si, and B; and (iii) an element consisting of O, the conductive agent containing a fibrous carbon.

Dependencies are inferred from the claim text.
