It is an object to provide a material for an electrode with improved electron conductivity and a power storage device using the material for an electrode. In a process for manufacturing a material for an electrode including a lithium phosphate compound represented by a general formula LiMPO4 having an olivine structure or a lithium silicate compound represented by a general formula Li2MSiO4 having an olivine structure, a metal element having a valence different from that of a metal element represented by M is added. The metal element having a different valence serves as a carrier generation source in the material for an electrode, whereby the electron conductivity of the material for an electrode is improved. By using the material for an electrode with improved electron conductivity as a positive electrode active material, a power storage device with larger discharge capacity is provided. |
