Boosting lifespan of conversion-reaction anodes for full/half potassium-ion batteries via multi-dimensional carbon nano-architectures confinement effect
文献摘要：
Transition metal selenides are regarded as prospective conversion-reaction anodes for potassium-ion bat-teries(PIBs)because of their relatively high electrical conductivity,large theoretical specific capacity,abundant resources and low cost.The challenge of the metal selenides originates from a serious volume change during cycling,which induces serious structural collapse and fast capacity degradation.In the pre-sent work,the multi-dimensional carbon nano-architectures confined bimetallic selenides(ZnSe/CoSe2@N-CNTs/rGO)were constructed by a facile MOF-assisted strategy.In such special nano-architectures,N-doped CNTs protect the metal selenides centers from serious volume expansion/electrode pulverization,as well as improve the sluggish kinetics.ZnSe/CoSe2@N-CNTs/rGO electrode boosts the lifespan of half PIBs with a large discharge specific capacity of 200 mAh g-1 at 2 A g-1 after 3800 cycles.The full PIBs battery with ZnSe/CoSe2@N-CNTs/rGO electrode as anode and Prussian blue as cathode exhi-bits well electrochemical performance(151 mAh g-1 at 100 mA g-1 after 100 cycles).DFT calculation sug-gests that the CNTs could change the K+adsorption energy and decrease K+diffusion energy barrier,which dramatically enhances K+storage kinetics.This work offers an effective material engineering approach for designing hierarchical"all-in-one"electrodes with high excellent cycling stability for PIBs.
