Lithium-rich cathode materials are some of the most promising choices for lithium-ion batteries due to their excellent energy density (>900 W h kg-1). However, severe voltage/capacity degradation during cycling has seriously hindered further commercialization lithium-rich materials. Current research efforts focused on enhancing voltage and capacity retention. Here, coating FeF3 specific crystal planes is utilized achieve a trend that very different from as-received material. Using this as an entry point, relationship between was studied in depth. The oriented coated material undergoes more drastic phase transition cycling, yet its decay remains basically same original sample (769.6 mV after 200 cycles, compared 723.5 sample). Notably, retention rate significantly improved (97% cycles vs. 75% pristine material). These findings suggest do not interact with each other does seem negatively affect voltage. This conclusion can also be extrapolated oxygen-reducing oxide systems help understand decay. modification generalized applicable
