Discovering a Novel Sodiation in FeF2 Electrodes for Sodium-Ion Batteries
نویسندگان
چکیده
As a promising alternative technology to the present electric energy storage utilizing Li-ion batteries, Na-ion batteries (NIBs) have attracted increasing interest for emerging large-scale applications due to the huge abundance and low cost of sodium [1]. Iron fluoride (FeF2) is a lithium-conversion cathode capable of accommodating multiple-charge transfer per formula unit, and the comprehensive evolution during its lithiation process has been experimentally examined [2, 3]. It is of great importance to verify whether FeF2 can be adapted to NIBs as well as to understand the underlying electrochemical mechanism of the sodiation reactions.

Materials degradation-the main limiting factor for widespread application of alloy anodes in battery systems-was assumed to be worse in sodium alloys than in lithium analogues due to the larger sodium-ion radius. Efforts to relieve this problem are reliant on the understanding of electrochemical and structural degradation. Here we track three-dimensional structural and chemical evolution of tin...
