Understanding the phenomenon of capacity increasing along cycles:In the case of an ultralong-life and high-rate SnSe-Mo-C anode for lithium storage
文献摘要：
A good cycling stability is a prerequisite for the application of metal-based materials in lithium-ion bat-teries(LIBs).However,an abnormal increase in capacity is often observed,which has rarely been focused on in many studies.In our SnSe-Mo-C composite anode,a high reversible capacity of 737.4 mAh g-1 remained after 5000 cycles at 5 A g-1 between 0.01 and 3.0 V versus Li/Li+.However,a continuous capac-ity increase occurred in the initial cycles,with 1086.9 mAh g-1 after 1000 cycles and 1216.9 mAh g-1 after 1500 cycles,respectively.Further studies revealed that the electrolyte decomposed at high poten-tials(2.5-3.0 V)and provided additional capacities.The cut-off voltage and electrolyte filling were con-trolled,which eliminated the impact of electrolyte decomposition,prevented rapid capacity decay,and provided a stable cycling performance for SnSe-Mo-C anodes in LIBs.This work shows that the composite anode is promising for lithium storage and the findings provide new insights into understanding and con-trolling the phenomenon of capacity increase with cycling in metal-based anode materials.
