PROBLEM TO BE SOLVED: To provide an all solid lithium battery in which the corrosion of a current collector is prevented and storage characteristics are enhanced by using lithium sulfide-silicon sulfide as the main component of a solid electrolyte and an alloy mainly comprising iron and containing a small amount of molybdenum in a positive current collector. SOLUTION: In a lithium battery using a lithium conductive electrolyte, a solid electrolyte mainly comprising lithium sulfide-silicon sulfide, for example 0.6Li2 S-0.4SiS is used as the electrolyte. The solid electrolyte can contain an oxygen atom bonded to a silicon atom by adding Li2 O if necessary, and is preferable to contain no corrosive halogen. As a positive current collector, an iron alloy mainly comprising iron and containing 0-1% Mo, which is low cost and easy to obtain is used. |
