Alloy negative materials for Li-ion batteries have been paid much attention because of high specific capacity and safety
but the research between alloy negative materials and the electrolytes was very fewIn this work
Cu6Sn5 alloy film electrode has been prepared by electroplating and heat-treatmentResearch result showed that alloy film electrode in LiN(CF2SO2)2(LITFSI) electrolyte presented higher discharge capacity and better cyclic capability than that in LiPF6 electrolyteCompared to 1mol·L-1 LiPF6/PC electrolyte
alloy film electrode in 1mol·L-1 LITFSI/EC∶DEC(1∶2) electrolyte had lower reaction resistance
larger reaction peak current density and good reversibility for Li+ insertion/desertionThe addition of EC could improve the electrochemical properties of alloy electrode due to the formation of solid electrolyte interface (SEI) film
