Description
Summary:[Display omitted] •Al foil anode shows reversible morphological evolution in all-solid-state batteries.•Al foil anode with high Li contents exhibits excellent kinetics.•The Li contents of Al foil anode is precisely regulated by pre-lithiation.•The all-solid-state full cells exhibit high-rate and long-cycling performance. Aluminum (Al) foil holds great promise as a pure alloy anode for all-solid-state batteries (ASSBs) due to its suitable potential, high theoretical capacity, and excellent electronic conductivity. However, it remains challenging to achieve high reversibility and stability of the Al foil anode for ASSBs. Herein, we investigate the morphological and lithium (Li) kinetics evolutions of the Al foil anode paired with sulfide solid-state electrolyte (SSE). We identify that the significant reversible capacity loss stems from diminished Li kinetics at low Li contents (LixAl, 0
