| 英文摘要 | Hard carbon is hard to be commercialized due to its low initial efficiency. The irreversible capacity loss usually consumes numerous lithium ions from the electrolyte, leading to an unexpected energy density attenuation. Therefore, effective pre-lithiation methods are extremely desired. Herein, a striking and simple pre-lithiated method was proposed through introducing lithium metal passivation powder into ionogel electrolyte as lithium source. Safety features and electrochemical performances of as prepared ionogel electrolyte were studied systemically. Notably, our work found that the incorporation of lithium metal powder could effectively improve the ionic conductivity, reduce the reactive activation energy, and supplement the lithium-ion loss of electrolyte. The pre-lithiated electrolyte could stand an ultra-high operating potential window of 4.2 V in lithium-ion capacitors. Moreover, our study reveals that the dissociation of the ionic clusters within the ionogel electrolyte favors the electrochemical performances at high temperature. Our optimized device delivered a maximum energy density of 138 Wh kg-1 and a maximum power density of 19339.4 W kg-1 at 60 degrees C. This simple prelithiation method will significantly benefit the rational fabrication of lithium-ion capacitors with high energy density and reasonable safety. |
