Fig. 6: NCM-811//Li pouch cells used a quasi-solid electrolyte under harsh working conditions.

a Schematic illustration of the cell structure and digital photo of an NCM-811//Li pouch cell assembled with a MOF-based quasi-solid electrolyte. b Discharge/charge curves and c the corresponding cycling performances of the NCM-811//Li pouch cell assembled with a quasi-solid electrolyte under a high cathode mass loading (approximately 20 mg cm−2) and at high temperature of 90 °C (yellow curve). The blue curve represents the cycling performance obtained at room temperature (25 °C). d Discharge/charge curves and e the corresponding cycling performances of the NCM-811//Li pouch cell assembled with a typical liquid electrolyte under a high cathode mass loading (~20 mg cm−2) and room temperature of 25 °C (blue curve). The yellow curve represents the cycling performance obtained at a high temperature of 90 °C. f Cycling performance of an NCM-811//Li pouch cell (NCM-811 cathode mass loading approximately 20 mg cm−2) assembled with a MOF-based quasi-solid electrolyte under a harsh working environment of high working temperature (90 °C) and after sustaining damage (bent and cut).
