Lithium has high specific capacity (3840 mAh/g) compared with other metal-air battery materials (820 mAh/g for Zinc, 2965 mAh/g for aluminium) making it an excellent choice for an anode material. However, there are some issues associated with metallic lithium as the anode. Upon charging/discharging in aprotic cells, a multilayer deposition of lithium salts creates a mass diffusion barrier between the lithium and electrolyte which initially prevents further corrosion of the lithium metal but eventually inhibits the reaction kinetics between the anode and the electrolyte. This chemical heterogeneity of the solid-electrolyte interface (SEI) results in morphologically heterogeneous structure prone to non-uniform current distributions. Uneven current distributions further the dendrite growth and typically leads to a short between the anode and cathode. Also, in aqueous cells problems at the SEI stem from the high reactivity of lithium metal with water.

Lithium has high specific capacity (3840 mAh/g) compared with other metal-air battery materials (820 mAh/g for Zinc, 2965 mAh/g for aluminium) making it an excellent choice for an anode material. However, there are some issues associated with metallic lithium as the anode. Upon charging/discharging in aprotic cells, a many layers of lithium salts get deposited on to the anode that eventually covers it creating a barrier between the lithium and electrolyte. This barrier initially prevents further corrosion of the lithium metal but eventually inhibits the reaction kinetics between the anode and the electrolyte. This chemical change of the solid-electrolyte interface (SEI) results in an unevenness and difference in chemical composition through out the surface, causing the current to vary from one point to another point. The uneven current distributions furthers the branch like growth and typically leads to a short between the anode and cathode. Also, in aqueous cells problems at the SEI stem from the high reactivity of lithium metal with water.
