摘要

•Bi0.8Ba0.2F2.8 is prepared as a new fluoride shuttle battery electrode material.•Bi0.8Ba0.2F2.8 decomposes into metallic Bi and BaF2 by defluorination.•Conversion reaction between Bi and BiF3 occurs in the subsequent cycles.•Cycle performance may be improved by suppression of coarsening of BiF3 particles.
