Battery Technology

Lithium-ion batteries, commonly used in laptops and cell phones, have a relatively short life span because they use a graphite anode, which wears out quickly with normal usage. Altair Nanotechnologies has developed nanomaterials that resulted in safer, more powerful batteries.

The Altair team substituted the carbon anode with lithium titanate (LiTiO) nanocrystals, which makes the battery last longer. Lithium Titanate or Lithium Titanium Oxide nanocrystals are typically 10 to 100 nanometers.

Using the lithium titanate nanocrystals also lengthened the life of a lithium-ion battery from 750 recharges to between 10,000 and 15,000 recharges. The nanocrystals also made the battery safer.
