In the quest for next-generation cathodes for Li-ion batteries, our group has come up with a novel metal fluorosulphate material LiFeSO4F tying the benefits of sulphate polyanions with fluorine chemistry. It delivers excellent capacity (~140 mAh/g) i

Developing the next generations of Li- and Na-ion batteries relies on designing new sustainable, low-cost and safe electrode materials. In such an attempt, we investigated several series of bimetallic sulfates, among them we identified Na2Fe(SO4)2·4
