| 英文摘要 | oligo(ethylene oxide)-functionalized trialkoxysilanes were synthesized through hydrosilylation reaction by reacting trialkoxysilane with oligo(ethylene oxide) allyl methyl ether using pto2 as a catalyst. the physical properties of these compounds, such as viscosity, dielectric constant, and ionic conductivity, were characterized. among them, [3-(2-(2-methoxyethoxy)ethoxy)-propyl]triethoxysilane (tesm2) exhibited a commercial viable ionic conductivity of 1.14 ms cm(-1) and a wide electrochemical window of 5.2 v. a preliminary investigation was conducted by using tesm2 as an electrolyte solvent for high-voltage applications in lithium-ion batteries. using 1 m lipf6 in tesm2 with 1 vol% vinyl carbonate as an electrolyte, licoo2/li half-cell delivered a specific capacity of 153.9 mah g(-1) and 90 % capacity retention after 80 cycles (3.0-4.35 v, 28 ma g(-1)); li1.2ni0.2mn0.6o2/li4ti5o12 full cell exhibited the initial capacity of 161.3 mah g(-1) and 86 % capacity retention after 30 cycles (0.5-3.1 v, 18 ma g(-1)). |
