过渡金属氧化物用作锂空气电池催化剂
Using transition metal oxide as catalyst of lithium-air battery
摘要
Abstract
The catalytic performance of 4 kinds of transition metal oxides such as MnO2 ,V2 O5 ,Sb2 O3 and CeO2 used as catalyst of lithium-air battery was compared;effect of crystal type of MnO2 to the performance of lithium-air battery was studied. Porous nano-spheres birnessite-type manganese dioxide(Bir-MnO2 )had the best catalytic performance. While the mass ratio of Bir-MnO2 ,Super P graphite and poly(vinylidene fluoride)in the electrode was 1∶3∶1 ,when cycled in 2.0~4.5 V with the current density of 0.05 mA/cm2 ,the specific discharge capacity of the prepared lithium-air battery could reach to 832.60 mAh/g,the capacity retention rate was higher than 52% in the 5th cycle.关键词
