Altair Nanotechnologies to Demonstrate Advances in NanoSafe(TM) Rechargeable Battery Program

RENO, Nev.--Sept. 12, 2006--Advances in the manufacture of safe, fast-charging, long-lasting batteries used to power electric and hybrid electric vehicles will be addressed by Altair Nanotechnologies Inc. at the California Air Resources Board Zero Emission Vehicle (ZEV) Technology Symposium, held September 25-27, 2006 in Sacramento, California.

On September 27, at 2:30 p.m., Evan House, Ph.D., Director of Altairnano's Advanced Materials & Power Systems business unit, will deliver a presentation on Altairnano's NanoSafe(TM) rechargeable nano-titanate battery program. In addition, Altairnano will demonstrate its NanoSafe battery technology throughout the Zero Emission Vehicles conference.

A leader in advanced nanomaterials and alternative energy solutions, Altairnano has forged an innovative path in battery chemistry by replacing graphite (which can cause batteries to malfunction or explode under certain conditions) with its patented nano-titanate material which is safe and reliable.

Altairnano's nano-titanate material can be charged and discharged significantly more often than conventional batteries because of the absence of particle fatigue that plagues graphite. Conventional lithium ion batteries can be charged about 750 times before they are no longer useful. In comparison, Altairnano NanoSafe battery cells have now achieved over 9,000 charge and discharge cycles at rates up to 40 times greater than are typical of common batteries, while retaining up to 85 percent charge capacity.

"It's an honor to be invited to present at the California Air Resources Board Zero Emission Vehicle Symposium and we look forward to providing substantive details on the role Altair Nanotechnologies is playing in making safe, powerful, long life, reliable electric vehicles a mass-market reality," Altair Nanotechnologies, Inc. President and Chief Executive Officer Alan J. Gotcher, Ph.D said.
