英文摘要The unstable electrolyte interphase layer on the surface of V2O5 limits its Li+ storage capability. Herein, a novel aminoakyldisiloxane compound, (3-(N,N-dimethylamino)diethoxypropyl) pentamethyldisiloxane (DSON), is applied as an efficient electrolyte additive for enhancing the electrochemical performance of V2O5 electrode. DSON additive in the conventional carbonate-based electrolyte can inhibit the generation of acidic species by suppressing the hydrolysis of LiPF6. Additionally, DSON can also induce the formation of solid electrolyte interphase on the surface of V2O5 electrode upon (de)lithiation, which decreases the charge transfer resistance of Li+ at the interface between electrode and electrolyte. Thus, the V2O5 electrode with the electrolyte containing DSON additive (0.5 wt%) delivers a higher specific capacity (311.8 mAh g-1 at 0.1 C), excellent cycling performance (248.1 mAh g(-1) at 0.5 C after 250 cycles) and rate performance (235.9 mAh g(-1) at 2 C). This work demonstrates that aminoakyldisiloxane is an effective electrolyte additive to stabilize the surface electrolyte film and improve the Li+ storage capability of metallic oxide-based electrode materials.
