LITHIUM BATTERY AND METHOD FOR PRODUCING THE SAME |
摘要 |
A lithium battery that contains a solid electrolyte but has a high capacity is provided.
A lithium battery 1 includes: a positive-electrode layer 13; a negative-electrode layer 14; and a sulfide solid electrolyte layer (SE layer 15) provided between the layers 13 and 14. The lithium battery 1 has a positive-electrode covering layer 16 and a buffer layer 17 formed between the layers 13 and 15 for suppressing nonuniformity of distribution of lithium ions in a region near the interface between the layers 13 and 15. In the battery 1, the positive-electrode covering layer 16 contains LiCoO 2 whereas the positive-electrode layer 13 does not contain LiCoO 2 . |
