To improve reversibility, intercalation-type cathodes can be viable alternatives. Few systems were studied and/or suggested . Among them, Ruddlesden Popper-type ((RP) An+1BnO3n+1, n=1,2.) intercalation-based cathodes were found to be promising. Here, A is a rare earth or alkaline earth element and B is a transition metal ion. Within the crystal structure, an empty layer of interstitial anion sites is found between the perovskite and rock salt layer, which can be intercalated and deintercalated by the fluoride ions during the charging and discharging process . Such cathodes are known to undergo significantly lower volume changes (~20%) compared to that conversion-type cathodes (~50 -200 %), hence reducing contact loss between the active material, carbon additive and the ion conductive additive on cycling.
