Abstract

The tavorite structured LiFeSO4F forms a potential cathode with an attractive mix of high redox voltage (ca 3.6 V) and reversible capacity (∼140 mAh/g). It exists as a metastable phase capable of showing polymorphism that can be thermodynamically or chemically triggered. Fluorosulphate (LiMSO₄F) belongs to a structurally diverse family of compounds. Here, we demonstrate the effect of Mn and Zn substitution on the structural and electrochemical properties of the parent LiFeSO₄F. Mn and Zn substitution into LiFeSO₄F stabilizes the triplite and sillimanite phases respectively, tuning the Fe²⁺/Fe³⁺redox activity in the voltage range of 3.6∼3.9 V, respectively. Notably, the polymorphism in LiFeSO4F leads to the realization of cathode material with the highest Fe²⁺/Fe³⁺redox potential close to 4 V.
