POSITIVE ELECTRODE FOR LITHIUM AIR BATTERY WITH IMPROVED STABILITY COMPRISING MANGANESE OXIDE IN WHICH TRANSITION METAL IS DOPED, A MANUFACTURING METHOD THEREOF, AND A LITHIUM AIR BATTERY COMPRISING THE SAME

摘要

PURPOSE: A positive electrode for lithium air battery is provided to provide a lithium air battery of which energy efficiency and capacity are improved by comprising a catalyst of improved stability.;CONSTITUTION: A positive electrode(15) comprises a positive electrode active material which is oxygen, and a redox catalyst(17) of the oxygen. The catalyst comprises manganese oxide in which one or more transition metal of zinc, cobalt, iron, copper and nickel is doped. A manufacturing method of the positive electrode comprises: a step of adsorbing the transition metal to the carbonic material by contacting the carbonic material to transition metal salt-saturated alcohol solution; and a step of adsorbing transition metal-doped oxide by contacting the carbonic material to manganese oxide precursor aqueous solution.;COPYRIGHT KIPO 2012
