General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more information.

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.
