Challenges of anode in metal batteries and the summary of strategies to inhibit dendrite growth. Schematic illustration of metal anode challenges having a uneven SEI and cracks, b metal volume change, c dead metal detached from anode surface and d dendrite formation touching the cathode side causing short circuit. e 2D materials modification from three aspects of anode design, separator engineering and electrolyte modification
