【 摘 要 】

tsThe unique 0D-2D ZnS nanodots/Ti3C2Tx MXene hybrids with strong interfacial interaction enable to achieve stable cyclability and excellent rate performance for lithium storage.The lithium storage mechanism of ZnS is clarified and new insights into phase transition mechanism are proposed.The strong interfacial interaction between ZnS nanodots and MXene nanosheets at the ZnS-MXene heterointerface exhibits high lithium adsorption capability, enhanced interfacial electron transfer, and low lithium diffusion energy barrier.
