We evaluated the combined effect of a high-deformation property and the use of a high ionic conductivity solid electrolyte in a non-sintered positive composite electrode. The battery performance of the positive electrode fabricated only by pressing was improved by inter-particle contact due to it being filled with a deformable solid electrolyte between a high ionic conductivity solid electrolyte and a positive active material. The positive composite electrode demonstrated a relatively high capacity of over 145mAh g(-1) at 60 degrees C.
