In this work, an ionic liquid (IL), EMIBF4 and solid electrolyte, LAGP and NZSP, were applied as electrolyte to improve the safety of Li-ion battery. The charge-discharge behaviors were confirmed at 25℃ and 80℃ in LVP/LVP and NVP/NVP with EMIBF4 as electrolyte. And the discharge capacity of all-solid-state-battery with LAGP was 40 mAh/g at 25℃ and 95 mAh/g at 80℃, respectively. Then, And the discharge capacity of all-solid-state-battery with NZSP was 35 mAh/g at 25℃ and 80 mAh/g at 80℃, respectively. Moreover, the reversible capacity of 70 mAh/g was confirmed at 25℃ by adjusting the cathode/anode ratio of LVP/LAGP/LVP.
