MATÉRIAU ACTIF D'ÉLECTRODE NÉGATIVE ET ÉLECTRODE NÉGATIVE DE BATTERIE TOUT SOLIDE LE COMPRENANT

摘要

Provided is a solid state battery which solves the problems of the conventional solid state battery, and is effectively inhibited from a dimensional change caused by charging/discharging, an increase in internal resistance and degradation of charging/discharging characteristics or cycle life at a high current. The solid state battery is provided with an electrode active material layer including a negative electrode active material, a solid electrolyte and a conductive material, wherein the negative electrode active material includes a carbonaceous material and the carbonaceous material includes a plurality of pores, a porosity of 10-60 vol%, and a pore size of 100-300 nm based on the largest diameter of the pores.
