LITHIUM PRIMARY BATTERY AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a lithium primary battery comprising a positive electrode, a negative electrode, an organic electrolyte solution and a separator interposed between the positive electrode and the negative electrode. The negative electrode contains a negative electrode active material, and the negative electrode active material is composed of at least one substance selected from the group consisting of lithium metal and lithium alloys. At least the surface layer of the negative electrode is composed of a composite material of an amorphous carbon material and the negative electrode active material, and the surface layer is arranged opposite to the positive electrode via the separator. Such a lithium primary battery is highly reliable and excellent in large current discharge characteristics at low temperatures and storage stability at high temperatures.
