"lithium-superrich iron oxide cathode cyclability improved doped with small amounts of aluminum, silicon, phosphorus, or sulfur, due to formation of strong covalent bonds between dopant and oxygen... problematic oxygen release less energetically favorable so less likely...  improvements in the cathode’s energy capacity, stability and the cycling between charging and discharging phases, showing an increase in capacity retention from 50% to 90%"
