項目摘要
高容量的鋰離子電池負極材料的開發對於提高鋰離子電池儲能密度具有重要意義。但高容量的材料如矽和錫由於在充放電過程中體積變化很大，因此循環性差。本課題通過設計碳包覆型納米複合結構，利用碳緩衝充放電過程中的體積變化，提高矽和錫的循環性能，獲得高性能的鋰離子電池負極材料。本課題在複合材料製備中引入電漿這一高效的反應介質，特別是針對複合材料的形成特點，提出了新型的雙電漿反應技術，利用兩個能夠獨立控制的電漿區域分別實現矽、錫納米顆粒的生成和碳層的包覆，能夠實現對矽、錫顆粒的尺寸和結晶性、碳包覆層厚度和形態等複合結構性能的靈活調控。雙電漿的設計將複合結構形成的兩個步驟在空間和時間上有效的分隔開，在複合結構製備中具有廣泛的通用性。本課題的研究不僅能夠有效的促進高性能鋰離子電池負極材料的開發，對於電漿合成技術的創新，特別是在複合納米材料的製備中的套用也具有重要意義。
