Abstract
There is provided an all-solid lithium battery having excellent output characteristics. The battery has a cathode, an electrolyte layer, and an anode. The cathode contains a cathode active material represented by formula (1) and a sulfide solid electrolyte, and the electrolyte layer contains a sulfide solid electrolyte:
LiaNibCocMndMeOf+σ (1)
(1.01≦a≦1.05; f: 2 or 4; σ: not less than −0.2 and not more than 0.2; M: Mg, Ca, Y, rare earth elements, etc.; provided that when f=2, 0≦b≦1, 0≦c≦1, 0≦d≦1, 0≦e≦0.5, and b+c+d+e=1; when f=4, 0≦b≦2, 0≦c≦2, 0≦d≦2, 0≦e≦1, and b+c+d+e=2).
