Albemarle is a leading supplier of lithium salts, a critical ingredient for the batteries in electric vehicles. The flow of lithium ions from the negative to positive electrode in the battery system is what enables the battery to be recharged. Lithium is the material of choice due to its unique properties, which drive higher energy density, reduced weight and faster charge times.
Lithium salts, in the form of lithium hydroxide and lithium carbonate, can be used throughout the lithium-ion battery. For conventional lithium-ion batteries, our lithium carbonate is used as a precursor to lithium hexafluorophosphate, a critical ingredient for liquid electrolyte.
Our primary EV application for lithium salts is for the cathode. Generally, lithium hydroxide is used for high nickel chemistries, which enable higher energy density at the cell level. Lithium carbonate is predominately used for the manufacturing of lithium-ion phosphate chemistries, which generally offer longer cycle life, reduced risk for thermal runaway and reduced raw material inputs. Both lithium hydroxide and carbonate have overlap as raw materials for mid-nickel chemistries.
