Fig. 1: Analysis of lithium metal anode thickness in solid-state batteries.
From: Techno-economic assessment of thin lithium metal anodes for solid-state batteries
a–c, Schematics of SSBs with varying anode thicknesses: zero lithium excess (a), 17 µm (b) and 100 µm (c). d, Volumetric energy density as a function of anode thickness (dashed lines represent the maximum permitted anode thickness to achieve 1,000 Wh l−1, when an areal capacity of 5.4 mAh cm−2 is used). e, CE required to maintain 75% capacity after 1,250 cycles (dashed lines represent the minimum required CE to maintain 75% capacity after 1,250 cycles when an areal capacity of 5.4 mAh cm−2 and a starting volumetric energy density of 1,000 Wh l−1 are used).
