发明名称 AIR ELECTRODE
摘要 PURPOSE:To increase high rate discharge performance and electrolyte leakage resistance by carrying either one or both of fluorine solvent and/or perfluoro compound on air electrode comprising three layers of a current collector, a water repellent layer, and a catalyst layer. CONSTITUTION:In a combined air electrode comprising three layers of a current collector, a water repellent layer, and a catalyst layer, the water repellent layer consists of a porous layer obtained by binding fluorocarbon with a water repellent binder, and the catalyst layer consists of a porous layer obtained by binding activated carbon or activated carbon carrying catalysts having oxygen reduction ability with a water repellent binder. Either one or both of fluorine solvent and/or perfluoro compound are carried on both of the layers. Thereby a thin air electrode having high rate discharge capability over a long time and good electrolyte leakage resistance are provided. perfluoro-n-butylamine or perfluorotripropylamine are used as perfluoro compounds. These perfluoro compounds increase high rate discharge performance of the electrode and improve water repellent performance to improve electrolyte leakage resistance, and response performance of the electrode by quickly acting as a donor or acceptor of oxygen.
