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: LiNi_0.8Co_0.1Mn_0.1O₂; LFP: LiFePO₄; PEO:LLZO: polyethylene oxide:Li₇La₃Zr₂O₁₂.
