Lithium titanate  Lithium titanate is a compound with the chemical formula Li2TiO3. It is a white powder with a melting point of . Lithium titanate is the anode component of the fast recharging lithium-titanate battery. It is also used as an additive in porcelain enamels and ceramic insulating bodies based on titanates. It is frequently utilized as a flux due to its good stability. In recent years, along with other lithium ceramics, metatitanate pebbles have been the subject of research efforts towards tritium breeding materials in nuclear fusion applications. The most stable lithium titanate phase is β-Li2TiO3 that belongs to the monoclinic system. A high-temperature cubic phase exhibiting solid-solution type behavior is referred to as γ-Li2TiO3 and is known to form reversibly above temperatures in the range 1150-1250 °C. A metastable cubic phase, isostructural with γ-Li2TiO3 is referred to as α-Li2TiO3; it is formed at low temperatures, and transforms to the more stable β-phase at 400 °C. The sintering process is taking a powder, putting it into a mold and heating it to below its melting point. Sintering is based on atomic diffusion, the atoms in the powder particle diffuse into surrounding particles eventually forming a solid or porous material. It has been discovered that Li2TiO3 powders have a high purity and good sintering ability. Lithium titanate is used as a cathode in layer one of a double layer cathode for molten carbonate fuel cells. These fuel cells have two material layers, layer 1 and layer 2, which allow for the production of high power molten carbonate fuel cells that work more efficiently. Li2TiO3 is used in the cathode of some lithium-ion batteries, along with an aqueous binder and a conducting agent. Li2TiO3 is used because it is capable of stabilizing the high capacity cathode conducting agents; LiMO2 (M=Fe, Mn, Cr, Ni). Li2TiO3 and the conduction agents (LiMO2) are layered in order to create the cathode material. These layers allow for the occurrence of lithium diffusion. The lithium-titanate battery is a rechargeable battery that is much faster to charge than other lithium-ion batteries.
