Fig. 2: Micromorphology and SEI properties of Li metal deposited onto a Cu substrate.
From: A dual-function liquid electrolyte additive for high-energy non-aqueous lithium metal batteries
SEM images (a–f), Young’s modulus maps (g–i) and force-displacement curves (j-l) of the deposited lithium metal using the BE (a, b, g and j), FE (c, d, h and k) and AFE (e, f, i and l) at current densities of 0.5 mA cm−2 and 3 mAh cm−2. “Extend” and “retract” means the direction of motion of the cantilever with respect to the sample.
