Altairnano Demonstrates Excellent Battery Performance at SEMA Show.

RENO, Nev. -- Altair Nanotechnologies Inc. (Nasdaq: ALTI), reported that the company produced and showcased their fast charge, long life, safe nano-Titanate batteries in Phoenix Motorcars' zero emission, all electric, freeway ready sports utility truck (SUT) and sports utility vehicle (SUV).

Altairnano and partners Phoenix Motorcars and Boshart Engineering have just returned from showcasing the zero emission Sport Utility Truck at the SEMA show (Specialty Equipment Market Association - www.sema.org), which was attended by more than 200,000 automobile industry people last week in Las Vegas, NV. During the SEMA show, Altairnano gave numerous interviews on the performance of the nano-Titanate product technology and demonstrated the battery packs safety and fast charge performance. This was the third exhibition in the past five weeks where Altairnano's NanoSafe[TM] battery pack powered zero emission, all electric, full sized Sport Utility Truck or Sport Utility Vehicle for industry and the public.

Altairnano's safe nano-Titanate battery packs allows the Phoenix sport utility truck (SUT) and sport utility vehicle (SUV) to exceed all specifications for the State of California Type III ZEV. Altairnano offers two nano-Titanate battery pack configurations: a 35 KWh and a 70 KWh NanoSafe pack. The 35 KWh NanoSafe pack can be recharged in less than 10 minutes, with the appropriate battery charger and provides sufficient power and energy for a fleet vehicle to travel up to 130 miles. The 70 KWh NanoSafe pack can also be recharged in less than 10 minutes, with the appropriate battery charger and provides sufficient power and energy for a full sized SUV to travel up to 250 miles. Altairnano is on track to deliver ten 35 KWh NanoSafe battery packs in the fourth quarter to Phoenix Motorcars and is prepared to supply additional 35 KWh NanoSafe battery packs to support Phoenix upcoming SUT market introduction build in early 2007 and SUV 35 KWh and 70 KWh battery packs in the later part 2007.

"Our nano-Titanate battery technology is performing as forecast. We have exhibited Altairnano's NanoSafe battery packs in a zero emission, all-electric, full size Sport Utility Vehicle and in full sized Sport Utility Truck. It is clear that our NanoSafe battery pack products provide distinctive market advantages such as safety, fast charge and long life over traditional rechargeable batteries," said Alan J. Gotcher, Ph.D., President and Chief Executive Officer of Altair Nanotechnologies Inc.
