Description
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 × 10−4 S/cm at room temperature and wide electrochemical stability window of over 5 V. The Li–O2 battery using such quasi-solid-state electrolyte exhibits a low charge-discharge overpotential at the first cycle and excellent long-term cyclability over 500 cycles. (paper)
