| 英文摘要 | a new aminoalkylsilane compound, ((2-(2-(n,n-dimethylamino)ethoxy)ethoxy) methyl)trimethylsilane (tmsc1n2) based on the oligo(ethylene oxide) chain end-capped with organosilicon functional group and alkylamine group on each end, was introduced as an electrolyte additive for lithium-ion batteries. electrochemical performances of different volume ratios of tmsc1n2 in the baseline electrolyte were conducted through cyclic voltammetry, electrochemical impedance spectroscopy and galvanostatic charge/discharge tests of lithium-ion batteries. with adding 5 vol.% tmsc1n2 to the baseline electrolyte (1 mol/l lipf6 in ethylene carbonate and diethyl carbonate (ec:dec = 1: 1, in volume)), the capacity retention of lifepo4/li cells could be significantly improved from 74.7% to 90.8% after 130 cycles. furthermore, tmsc1n2 showed good compatibility with graphite electrode and would not deteriorate the electrochemical performance of graphite/li anode cells. these data suggested that tmsc1n2 could be utilized as an effective additive for lithium-ion batteries. |
