Abstract
Various arrangements of an anode-free solid-state battery cell are presented herein. The battery cell can include a lithium ion buffer layer that is located between a solid-state electrolyte and an anode current collector. Lithium ions may be stored within the lithium ion buffer layer when the battery cell is charged, which can decrease an amount of swelling within the battery cell.
