英文摘要: Abstract(#br)The possibility of using vanadium pentoxide (V 2 O 5 ) as a catalyst in rechargeable lithium–oxygen (Li–O 2 ) batteries was studied. A V 2 O 5 -carbon composite was cast onto Ni foam to form a cathode. Electrochemical cells designed based on the flat cell manufactured by Hohsen Corporation were fabricated. The initial discharge capacity was 715 mA h g −1 , and the maximum discharge capacity reached 2,260 mA h g −1 during the twelfth cycle. The cell had high capacity retention during cycling (1.24 % during cycles 2–8). V 2 O 5 acted as a catalyst as well as an active material, improving the specific capacity and capacity retention of the non-aqueous Li–O 2 cell more effectively than do other materials.
