<P>PROBLEM TO BE SOLVED: To provide a lithium battery which excels in productivity having high capacity, while using a solid electrolyte and hardly deteriorates in its performance, in connection with charging and discharging. <P>SOLUTION: The lithium battery 1 includes a positive electrode layer 13, a negative electrode 14, and a sulfide solid electrolyte layer (SE layer) 15, and the battery includes a buffer layer 16 that buffers the deviation of lithium ions in the vicinity of the boundary of both layers for buffering the biasing of lithium ions, in between both the layers 13 and 15. If the area of a range coating the positive electrode layer 13 by a buffer layer 16 is set s Sc and the area of a range on which the positive electrode layer 13 is not coated by the buffer layer 16 is set as Su, the Sc, Su satisfies the relation: 0.000001<Su/(Sc+Su)<0.001. <P>COPYRIGHT: (C)2010,JPO&INPIT |
