LITHIUM-MANGANESE DIOXIDE SECONDARY BATTERY

摘要

PURPOSE:To increase charge-discharge cycle life by limiting the contents of lithium in lithium-aluminium alloy of an anode to the specified atomic percentage. CONSTITUTION:An aluminium foil is blanked in a diameter of 15.5mm and spot-welded an anode can 2. A lithium foil is blanked in a diameter of 15.0mm and pressed against the aluminium foil to form an anode pellet 1. The contents of lithium in the lithium-aluminium anode is limited to 30-45 atomic percent. Thereby, the charge-discharge cycle life is lengthened and the performance is remarkably increased.
