Na‐FeCl2 Batteries: A Low‐Cost Durable Na‐FeCl2 Battery with Ultrahigh Rate Capability (Adv. Energy Mater. 10/2020)

In article 1903472, Guosheng Li and co‐workers report an advanced high‐rate Na‐FeCl2 battery using low cost NaCl and crust‐rich Fe as cathode materials. The fast‐charging capability of the Na‐FeCl2 battery, rooted in a fast Fe/Fe2+ redox reaction, rapid NaCl‐Na6FeCl8‐FeCl2 phase transitions, and qui...

Description
Summary:In article 1903472, Guosheng Li and co‐workers report an advanced high‐rate Na‐FeCl2 battery using low cost NaCl and crust‐rich Fe as cathode materials. The fast‐charging capability of the Na‐FeCl2 battery, rooted in a fast Fe/Fe2+ redox reaction, rapid NaCl‐Na6FeCl8‐FeCl2 phase transitions, and quick Fe2+ lattice diffusion within FeCl2, revamps the understanding of Na‐metal halide batteries.
