Altairnano lithium titanate battery

How looking at using this battery in the Volt. It gets faster recharge time and longer distance on each charge. Plus it is said to last 20+ years. Also it is an American company that builds the batteries so that will help keep the Volt more domestic than the battery companies they are looking at now.
