高能量密度與高安全性全固態鋰電池
Using PVDF-HFP, lithium salt, LLZOplasticizer to prepare HSE membrane (ơi=4.6×10-4 S/cm, 25oC). The Free-standingcathode-supported membranes in the pouch-type NCM811HSELi ASSLBs were designed to enhance the mechanical strength (Li-Nafion-coated cellulose support, the total membrane thickness is 40-60 µm), improve Li-ion conductivity (Doped LLZO/Li salt), reduce interfacial impedance (PVDF-HFP/Li salt/plasticizer),inhibit Li dendritic deposition. The energy density of the ASSLBs has reached 300 Wh/kg, which exceeds the current best LIBs by 50.
