Impact of Mg Substitution on the Structure, Stability, and Properties of the Na2Fe2F7 Weberite Cathode
{{output}}
Of the few weberite-type Na-ion cathodes explored to date, Na2Fe2F7 exhibits the best performance, with capacities up to 184 mAh/g and energy densities up to 550 Wh/kg reported for this material. However, the development of robust structure-property relationsh... ...
