Solidification for solid-state lithium batteries with high energy density and long cycle life

Figure 1. (A) Gravimetric and (B) volumetric energy density as a function of the mass loading of cathodes, which increases from 10 to 40 mg cm-2 and from 13 to 40 mg cm-2 for NCM/Li and LFP/Li pouch cells, respectively, with a fixed PEO:LLZO composite electrolyte with a mass density of 1.6 g cm-3 and thickness of 100 μm. (C) Gravimetric and (D) volumetric energy density as a function of electrolyte thickness, which is reduced from 500 to 10 μm for the NCM/Li pouch cell with a fixed cathode mass loading of 22 mg cm-2. The corresponding calculation parameters are listed in (E) and (F), which are based on the battery operation temperature of 30 °C. NCM: LiNi0.8Co0.1Mn0.1O2; LFP: LiFePO4; PEO:LLZO: polyethylene oxide:Li7La3Zr2O12.
