PURPOSE:To provide a lithium battery of high energy density having large electric capacity and generating high electromotive force and high discharge voltage. CONSTITUTION:In a lithium battery constituted of a negative electrode unit consisting of metal lithium or its alloy, positive electrode unit and an electrolyte, an active material of the positive electrode unit consists of lithium phosphorus compound oxide. Accordingly, an Li<+> amount fetched to the positive electrode unit can be increased, and since an Li<+> amount fetched per unit weight to the positive electrode unit can be increased, the lithium battery of high energy density having large electric capacity and further generating high electromotive force and high discharge voltage can be obtained. |
