Application

Lithium sulfate can be used:
  • In the pretreatment of graphite electrodes of lithium-ion batteries(LIBs). LiSO4-treated electrodes show excellent cycling performance and low interfacial impedance resulting in faster charging of LIBs.
  • As a precursor to synthesize sheet-like Li2S@C nanocomposites which are cathode materials for LIBs.
  • As an electrolyte for intermediate temperature fuel cells.
  • As a processing additive to protect Ni-rich layered oxide cathodes, resulting in improved electrochemical performance.
