Abstract
Various arrangements of an anode-free battery cell are presented herein. The battery cell can include a lithium ion buffer layer that is located between a 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.
