Aqueous zinc-ion batteries: taming the zinc anode, from electrolyte to cathode

A honeycomb of twelve tiles on aqueous zinc-ion batteries: why zinc is an attractive anode in water (820 mAh g⁻¹, −0.76 V, safe), what goes wrong on it (hexagonal dendrites, hydrogen gas, corrosion and by-products), how electrolytes and interfaces fix it (additives that rebuild the Zn²⁺ water shell, water-in-salt electrolytes, a graphene template), and the MnO₂ and vanadium-oxide cathodes that host Zn²⁺.
