Applications
Beyond lithium-ion battery cathode materials (LFP, NMC, NCA), lithium carbonate has diverse industrial applications. In the ceramics and glass industry, it acts as a flux that lowers melting temperatures and improves the thermal shock resistance of glass-ceramics and cookware (e.g., Pyroceram-type glass). Pharmaceutical-grade lithium carbonate is an established mood-stabilising medication for bipolar disorder treatment. In aluminium smelting, small additions of lithium carbonate to the electrolyte bath reduce energy consumption and improve cell efficiency. Lithium carbonate is also used in the manufacture of lithium grease (lithium stearate), the most widely used automotive and industrial lubricating grease thickener. For battery applications, battery-grade lithium carbonate requires purity ≥99.5% with strict limits on Na, K, Ca, Mg, and heavy metal impurities. Conversion: approximately 5.3 tonnes of lithium carbonate equivalent (LCE) are required to produce 1 tonne of lithium metal for battery applications.
