Abstract

Anode-free batteries (AFBs) represent a transformative approach in energy storage technologies, eliminating the anode to achieve remarkable improvements in energy density, safety, and manufacturing simplicity. This review provides a comprehensive analysis of the fundamental phenomena governing the operation of AFBs during metal plating and stripping, including nucleation and growth, dendrite formation, dead lithium formation and regeneration mechanisms, morphological evolution, and electrolyte decomposition. The challenges associated with AFBs are critically examined, alongside various designed innovative strategies. Expanding the discussion beyond lithium, this review explores advancements in anode-free…
