Lithium titanate

Lithium titanates are chemical compounds of lithium, titanium and oxygen. They are mixed oxides and belong to the titanates. The most important lithium titanates are:

  • lithium titanate spinel, Li4Ti5O12 and the related compounds up to Li7Ti5O12. These titanates are used in lithium-titanate batteries.
  • lithium metatitanate, a compound with the chemical formula Li2TiO3 and a melting point of 1,533 °C (2,791 °F) It is a white powder with possible applications in tritium breeding materials in nuclear fusion applications.
