ABSTRACT=Cation-disordered rock-salt cathodes are promising materials that could deliver high capacities with earth abundant elements and materials. Fluorination of cation-disordered rock-salts is superior to other types of cathode compounds, and has been found to enhance the material performance. However, fluorinated cation-disordered rock-salts suffer from rapid material deterioration and low scalability which limit their practical applications. This mini-review highlights the key challenges to enable commercialization of fluorinated cation-disordered rock-salts, discusses the underlying reasons behind material failure and proposes future development directions.
