BI-FUNCTIONAL ELECTROCATALYST BASED ON CU-FE ALLOY-HIGHLY CRYSTALLINE CARBON SHEETS FOR RECHARGEABLE ZN-AIR BATTERY.

摘要

Recently, metal-air battery regarded as Next-Generation battery because of its higher energy density, safety than commercial Li-ion battery.(1) However, current metal-air batteries have rechargeable problem due to sluggish rate of oxygen reduction and evolution.(2) Therefore, to improve rechargeable metal-air battery performance, oxygen electrochemistry is the key reaction in battery chemistry. Metal oxide containing carbon-supported materials have been reported to possible candidates for bi-functional electrocatalysts, but these catalysts show lower ORR activity compare to Non-precious metal catalysts.
