Fig. 4: Simulation of Li deposition in SE pores.
From: Effect of solid-electrolyte pellet density on failure of solid-state batteries
a Boundaries (dashed lines) of Li filament (gray area) at different charging times (in h) within a pore of 2-μm diameter. The Li metal on the top is the anode during charging. The maximum Li width at a specific time is the summation of the Li width on each side (W = w1 + w2). b Deposition current density along line A–B–E at different charging times. The labels “A”, “B”, and “E” along the x-axis correspond to locations A, B, and E in 4a. Note that location E changes at different time steps. c Maximum Li width in the pore when Dpore = 10 μm (dashed black line), Dpore = 2 μm (red line), Dpore = 1 μm (blue line), and Dpore = 0.5 μm (green line). d Length of Li filament in the pore when Dpore = 2 μm (red line), Dpore = 1 μm (blue line), and Dpore = 0.5 μm (green line).
