LITHIUM/IRON DISULFIDE PRIMARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a high-quality lithium/iron disulfide primary battery capable of suppressing increase of an open circuit voltage in storage. SOLUTION: This lithium/iron disulfide primary battery is provided with: a positive electrode 2 having a positive electrode mix containing iron disulfide being a positive electrode active material on a positive electrode collector; a negative electrode 3 having a negative electrode active material; and an electrolytic solution prepared by dissolving an electrolyte in an organic solvent. Copper foil is used for the positive electrode collector. Thereby, increase of the open circuit voltage in storage can be suppressed. COPYRIGHT: (C)2007,JPO&INPIT
