In article 1903472, Guosheng Li and co‐workers report an advanced high‐rate Na‐FeCl 2 battery using low cost NaCl and crust‐rich Fe as cathode materials. The fast‐charging capability of the Na‐FeCl 2 battery, rooted in a fast Fe/Fe 2+ redox reaction, rapid NaCl‐Na 6 FeCl 8 ‐FeCl 2 phase transitions, and quick Fe 2+ lattice diffusion within FeCl 2 , revamps the understanding of Na‐metal halide batteries.
