柔性多功能Fe2O3/CC正极宿主实现高效吸附与催化多硫化物的锂硫电池
A highly efficient absorptive and catalytic self-supporting Fe2O3/CC host for high performance Li-S batteries
摘要
Abstract
The lithium-sulfur(Li-S)battery is a promising energy storage system because of its high energy density and low cost.However,the shuttling of lithium polysulfides(LiPSs)and low conductivity of the S cathode are barriers to its practical application.Fe2O3 nanorods were grown on a carbon cloth(Fe2O3/CC)by a solvothermal reaction and calcination to obtain a cathode for the battery.The mesoporous structure of the Fe2O3 and the CC conducting network facilitates lithium-ion and electron transport.Meanwhile,the nanorod arrangement results in the exposure of more Fe2O3 active sites,which improves the adsorption and rapid conversion of LiPSs.As a result,a Li-S cell using a Fe2O3/CC cathode has a high capacity of 1 250 mAh g-1at 0.1 C with an excellent life of over 100 cycles with a capacity retention of 67％.It also has a 70％capacity retention after 1 000 cycles at 0.2 C.The excellent electrochemical performance of the Fe2O3/CC cathode indicates its potential applications in Li-S batteries.关键词
