Ultra-rapid microwave synthesis of triplite LiFeSO4F†
Abstract
Quick, effective synthesis of the 4 V Li-ion battery cathode material, triplite LiFeSO4F, takes place via facile conversion of the defect-peppered nanocrystalline tavorite precursor that forms on ultra-rapid microwave heating (10 min) of FeSO4·H2O/LiF. We propose a mechanism for its unique phase transformation to the triplite that occurs as a consequence of the disorder and
