摘要
A novel transparent and soft quasi-solid-state electrolyte(QSSE) was proposed and fabricated, which consists of ionic liquid(PYR14TFSI) and nano-fumed silica. The QSSE demonstrates high ionic conductivity of 4.6×10-4S/cm at room temperature and wide electrochemical stability window of over 5 V. The Li–O2battery using such quasi-solidstate electrolyte exhibits a low charge-discharge overpotential at the first cycle and excellent long-term cyclability over 500 cycles.
