Alkylsilane ethers, containing one or three carbon spacer groups between the silicon atom and oligo(ethylene oxide) moiety, were designed and synthesized. These compounds are non-hydrolyzable and less flammable than their alkoxysilane counterparts. A full cell test using them as electrolyte solvents showed good cycling performance in lithium-ion batteries.
设计并合成了含有一个或三个碳间隔基团的烷基硅烷醚,这些间隔基团位于硅原子和寡(乙烯氧化物)基团之间。这些化合物具有非水解性,并且比其醇氧基硅烷对应物更不易燃。在全电池测试中,将其用作电解质溶剂,显示出良好的锂离子电池循环性能。
