Popis: Conventional electrochemical processes are mainly operated by cationic redox chemistry. Developing cumulative cationic and anionic redox chemistry offers a transformative approach to increase the energy storage capacity of Li-ion batteries and active sites of catalysts. However, realizing the reversible anionic redox reaction to increase the specific capacity in Li-ion battery materials is a large challenge because uncontrollable anion-anion combination and gas evolutions cause poor cyclic performance. Here, we use open-framework metal-fluorides (FeF
