摘要

二氧化锡由于其低电位和高储钠理论容量以及绿色无毒的优点被认为是最有前途钠离子电池负极材料之一。但其导电性不好，且在嵌／脱钠的过程中会发生体积膨胀，从而导致电池的容量和循环稳定性等电化学性能下降。碳具有良好的导电性，同时能减缓材料在脱／嵌钠过程的体积膨胀，本文采用一步合成制备ＳｎＯ２／Ｃ复合纳米材料，并将其作为钠离子电池的负极材料进行研究。结果发现碳包覆花瓣状ＳｎＯ２复合材料相比于纯的ＳｎＯ２具有良好的储钠性能

Abstract:

SnO, is considered to be one of the most promising SIBs anode materials due to high theoreticalcapacity ,lower potential, environmental-friendly and non-toxic. But its conductivity is not good, and in theprocess of sodiation/desodiation, volume expansion will occur, resulting in the battery capacity and cyclestability and other electrochemical performance degradation. Because of carbon has good conductivity,and caninhibit the volume expansion of material in the process of sodiation/desodiation.Therefore , we prepared Sn0,/Cnanocomposites by one-step synthesis.When as the anodes of sodium-ion batteries( SIBs) , the carbon-coatedSnO, had better electrochemical properties than pure SnO,.

Key words: Sn0₂ sodium-ion battery nanocomposites electrochemical performance
