General description

Lithium hydroxide monohydrate is a strongly alkaline crystalline solid soluble in water. It is prepared industrially by recovering it from spodumene or by evaporating a solution prepared by reacting calcium hydroxide and lithium carbonate. It is mainly used in the synthesis of cathode materials for lithium-ion batteries, such as lithium cobalt oxide (LiCoO2) and lithium iron phosphate. It is also preferred over lithium carbonate for producing lithium nickel manganese cobalt oxides.
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 hydroxide monohydrate can be used mainly for the synthesis of cathode materials for Lithium-ion batteries:
  • To synthesize Olivine LiFePO4 nanoplates with different crystal orientations by glycol-based solvothermal process. It demonstrated that the crystal orientation of cathode nanoplates plays an important role in the performance.
  • As a precursor for the synthesis of LiFePO4 platelets under hydrothermal synthesis conditions. It exhibited homogeneous particle size distribution, greater electrochemical performances and cycle life, and morphology control.
  • To synthesize Ni-rich Li[NixCoyMn1–x–y]O2 gradient cathodes (NCM). These cathodes exhibited enhanced cycling and chemical stability due to their strong crystallographic texture, unique particle morphology, and highly correlated particle orientation.
  • As a precursor to prepare porous salt hydrate-based composites for low-temperature thermochemical heat storage.
  • As an electrolyte additive in lithium-ion batteries.
Our Lithium hydroxide monohydrate which is water soluble, with a purity of 99.95%, is an excellent choice as a source for Lithium to synthesize the cathode materials for Lithium-ion batteries. The high purity on trace metals basis makes it highly suitable for cathode formation, ensuring optimal electrochemical performance.
