主 题:1 T-MoS_(2) heterostructure lithium-ion batteries Sn coarsening SnO_(2)
摘 要:SnO_(2),with its high theoretical capacity,abundant resources,and environmental friendliness,is widely regarded as a potential anode material for lithium-ion batteries(LIBs).Nevertheless,the coarsening of the Sn nanoparticles impedes the reconversion back to SnO_(2),resulting in low coulombic efficiency and rapid capacity *** this study,we fabricated a heterostructure by combining SnO_(2)nanoparticles with MoS_(2)nanosheets via plasma-assisted *** heterostructure consists of in-situ exfoliated MoS_(2)nanosheets predominantly in 1 T phase,which tightly encase the SnO_(2)nanoparticles through strong *** configuration effectively mitigates the volume change and particle aggregation upon ***,the strong affinity of Mo,which is the lithiation product of MoS_(2),toward Sn plays a pivotal role in inhibiting the coarsening of Sn nanograins,thus enhancing the reversibility of Sn to SnO_(2)upon ***,the SnO_(2)/MoS_(2)heterostructure exhibits superb performance as an anode material for LIBs,demonstrating high capacity,rapid rate capability,and extended ***,discharged/charged at a rate of 0.2 A g^(-1)for 300 cycles,it achieves a remarkable reversible capacity of 1173.4 mAh g^(-1).Even cycled at high rates of 1.0 and 5.0 A g^(-1)for 800 cycles,it still retains high reversible capacities of 1005.3 and 768.8 mAh g^(-1),***,the heterostructure exhibits outstanding electrochemical performance in both full LIBs and sodium-ion batteries.
