NEGATIVE CURRENT COLLECTOR OF SECONDARY BATTERY

摘要

PURPOSE:To utilize for a long time by using a carbon plastic electrode in a negative current collector. CONSTITUTION:An addition complex of iodine and a polymer capable of forming addition complex with iodine and a component obtained by dispersing carbon in the addition complex are used as the active material of a positive electrode 10. A carbon palastic electrodes 20 is used in a negative current collector. The electrode (current collector) 20 does not dissolve in an electrolyte and is electrochemically for a long time. Zinc deposits on the carbon electrode 20 by charge and dissolves from the current collector 20 by discharge. The current collector 20 is not deteriorated by charge-discharge cycles and can be used for a long time.
