Lithium compounds are used to manufacture many products. Lithium carbonate and lithium hydroxide are needed for lithium-ion-batteries in mobile devices such as smartphones, tablet computers, and laptops, or in electric or hybrid vehicles. Butyllithium is needed for the production of synthetic rubber for tires. Lithium organics are versatile tools for the synthesis of pharmaceuticals, agrochemicals, or flavors and fragrances. The glass industry requires lithium carbonate or spodumene to improve the properties of glass. Lithium bromide is used in industrial absorption refrigeration systems that are installed in large buildings and industrial plants for air-conditioning or process cooling.
