Abstract
A lithium primary battery includes a positive electrode, a negative electrode, a separator, a positive electrode case, a negative electrode case, a gasket, and a non-aqueous electrolyte. The negative electrode includes: lithium or a lithium alloy; a lithium carboxylate layer formed on a surface of the lithium or lithium alloy; and a carbon layer formed on a surface of the lithium carboxylate layer. This configuration allows the lithium primary battery to have suppressed negative electrode polarization during discharge and improved large-current discharge characteristics in a low temperature environment and after high temperature storage.
