To provide composite powder for an electrode wherein without reducing weight energy density and volume energy density, the electrode in which charge and discharge characteristics at high current density have been improved can be obtained, and in which joining strength of an electrode active material and a conductive material have been improved, and to provide a method of manufacturing the same.
This is the composite powder for the electrode having a structure that the electrode active materials are mutually joined via the conductive material, and it can be obtained by filling a raw material mixture containing the electrode active material and the conductive material into a mold having conductivity, and by sintering the raw material mixture by energizing a direct current pulse current under pressure of 60 MPa or more.
