RENO, NV -- (MARKET WIRE) -- 02/10/2005 -- Altair Nanotechnologies, Inc. (NASDAQ: ALTI) announced today that it has achieved a breakthrough in Lithium Ion battery electrode materials, which will enable a new generation of rechargeable battery to be introduced into the marketplace, as well as create new markets for rechargeable batteries. These new materials allow rechargeable batteries to be manufactured that have three times the power of existing Lithium Ion batteries at the same price and with recharge times measured in a few minutes rather than hours.

The technical achievements are being praised by the battery community as truly remarkable and will likely enable a new generation of rechargeable battery to be produced. Altair has confidentiality agreements in place with some of the world's leading battery development companies to evaluate and commercialize these battery electrode materials.

Altair's research and development efforts were allowed two new patents (announced on January 7th and 14th, 2005) and a National Science Foundation grant was successfully completed in January, 2005, by Altair. New markets for fast charging batteries will include the handheld power tools market increasing the productivity of, for example, construction workers while lowering their overhead costs. Other markets include hybrid electric vehicles, portable electronics and medical surgery tools -- solving the problem of electrical wires all over the operating room floor.

Endorsements for Altair's work in this area have come from many quarters. Two eminent experts in battery technology, Dr. K. M. Abraham and Dr. Vassilis G. Keramidas, have expressed strong support for Altair's work

"The nanomaterials Altair is developing are the next generation of electrode materials for lithium-ion batteries and Altair's research and product development is laying the ground work for a new generation of ultra high power lithium ion batteries," commented Dr. K. M. Abraham. "A key requirement to the above applications is the ability to recharge the battery very quickly, for example in a few minutes. Current Li Ion batteries are incapable of such quick charge times because of the chemistry of the anode materials. Altair has found a solution to this with their nano-sized lithium titanium oxide."

"Altair's nanomaterials, which have a virtually zero strain crystal lattice, eliminate the main cause for battery electrode material fatigue, which limits rechargeable battery life, increasing the number of recharge and discharge cycles from a few hundred to many thousand cycles," said Dr. Vassilis G. Keramidas. "I find Altair's development strategy and proposed research direction sound and a necessary step in establishing the Li-Ion electrochemistry as a viable contender for large battery applications."

"Our research in battery electrode materials is a further indication of how Altair's scientists are able to apply their nanomaterials science knowledge to solving real world needs," commented Altair CEO Dr. Alan J. Gotcher. "Many of the technology and product development initiatives that we have been working on for the last few years are now coming to the commercialization stage. Each step is another validation of our business strategy and product technology platform. Altair's nanomaterial based, micro porous electrode technology has performance and stability advantages that appear to be unmatched when compared to the best commercialized technology in the market today."

Dr. K. M. Abraham

Dr. Abraham, the principal of E-KEM Sciences, has over 28 years of experience in lithium battery research and development. He has made pioneering contributions to the development of the rechargeable battery industry. Dr. Abraham has authored and co-authored over 150 publications and 16 US patents in battery technology. He received his Ph. D. from Tufts University and conducted post-doctoral research at Vanderbilt University and MIT. In 2000 he was elected a Fellow of the Electrochemical Society. Dr Abraham is on Altair's Scientific Advisory Board.

Dr. Vassilis G. Keramidas

Dr. Keramidas, Managing Director of Keramidas International, provides management consulting to major corporations on the formulation and execution of their research and development. Prior to founding Keramidas International, he was Vice President of Applied Research at Telcordia Technologies (formerly Bellcore). His division at Telcordia made seminal contributions in the fields of photonic and electronic materials. The Bellcore research on energy storage ushered in the polymer battery Li-Ion technology with the invention of the Bellcore Plastic Li-Ion (PLiON) technology. Dr. Keramidas sits on the Board of two battery companies.
