Abstract
An Object of the invention is to obtain an all solid lithium battery having an excellent output performance. To achieve the object, a sulfide based solid electrolyte is used as an electrolyte; an oxide containing lithium, a metal element that acts as a redox couple, and a metal element that forms an electron-insulating oxide is used as a cathode active material; and the concentration of the metal element that forms the electron-insulating oxide on the surface of the cathode active material (oxide) that is in contact with the sulfide solid electrolyte is made high.
