High Application Potential and Current Status for Lithium Titanate Batteries
The two leading companies in lithium titanate battery technology are Altairnano and Toshiba.
Altairnano announced the breakthrough of nano-structured lithium titanate battery technology in February 2005. They used this material to replace the carbon in conventional lithium-ion batteries and achieved better performance and a high potential for various energy storage applications.
Altairnano developed a series of lithium-titanate batteries for electric vehicle use and many electric-vehicle manufacturers announced their intention to use this new battery technology; the list includes Lightning Car Company, Phoenix Motorcars, Protera, etc. They are also currently collaborating with the US Navy in order to incorporate the new battery technology in Navy equipment. Finally, they have deployed these new energy storage systems for electric grid ancillary services as well.
Toshiba is the second leading company in the field. After having developed their own lithium-titanate battery, they dubbed it the "Super Charge Ion Battery," or SCiB. It is designed to offer 90% charge capacity in 10 minutes. They intend to use them as laptop batteries and also plan to use their SCiB for powering electric cars and bikes.
Currently, Toshiba is investing in a $279 million additional lithium titanate production facility in order to increase production. They estimate to reach $2.2 billion in sales by 2015.
