| 摘 要： | A novel transparent and soft quasi-solid-state electrolyte(QSSE) was proposed and fabricated, which consists of ionic liquid(PYR_(14)TFSI) and nano-fumed silica. The QSSE demonstrates high ionic conductivity of 4.6×10~(-4) S/cm at room temperature and wide electrochemical stability window of over 5 V. The Li–O_2 battery using such quasi-solidstate electrolyte exhibits a low charge-discharge overpotential at the first cycle and excellent long-term cyclability over 500 cycles.
