Looking back at the archive I realize we already talked about this Altair battery last year (May 2006 thread "Fully Charged in About 8 Minutes" initiated by Chris Zell), but they didn't deliver yet then, and there was no mention of titanate.
Still more on this here: http://www.autobloggreen.com/2007/06/05/breaking-gm-awards-two-battery-development-contracts-for-chevy/ Quote: "7. An Altairnano lithium titanate battery has been charged and discharged over 25,000 times with almost no loss in charge capacity. That's a lifetime of over 20 years people. It can be charged in less than 10 minutes. It doesn't overheat or have thermal runaway. It is currently being demonstrated on a 5 passenger truck and has a range of 135 miles, goes from 0-60 in 10 seconds, top speed of 95 mph." End quote. Although a bit heavy and expensive (the latter will change with volume hopefully), this battery does seem miraculous wrt fast charge and number of cycles! Quoting Chris: " The Really Good Battery: the one invention that will change everything from global warming to Arab governments."

More on these miracle batteries: http://www.phoenixmotorcars.com/news/2007/pr_070510.html Quote: ""The Altairnano NanoSafe battery is changing the future of transportation," said Daniel J. Elliott, CEO of Phoenix Motorcars. "Utility companies and government agencies are eager to add our all-electric commercial vehicles to their fleet inventory." Altairnano's all-battery packs will be installed in Phoenix Motorcars' sport utility trucks (SUT). Delivery is expected to begin summer 2007, including Pacific Gas and Electric Company's (PG&E) initial order of four SUTs. The battery pack is a 35KWh configuration that enables Phoenix Motorcars' SUT to travel at freeway speeds while carrying five passengers and a full payload. It exceeds all specifications for a Type III Zero Emission Vehicle (ZEV), having a driving range of over 100 miles, can be recharged in less than 10 minutes and the battery pack has a life of 12 years or more. " End quote. It seems they are actually delivering: http://www.greencar.com/index.cfm?content=phoenix_electrified Quote: "Power comes from 900 pounds of Altair NanoSafe lithium titanate batteries. Vehicle integration and testing are by Boshart Engineering. The powertrain is no slouch, producing over 400 ft-lbs of torque and accelerating this electrified SUT from 0-60 mph in under 10 seconds. It features an electronically governed top speed of 95 mph with a claimed driving range of 100 miles. An integrated on-board charger allows charging in about six hours from a 220-volt outlet. Charging in 10 minutes is said to be possible with a high-power commercial rapid charger, although these are quite costly and there is no network of readily-available rapid chargers around outside of an unrelated test program in Hawaii (see the feature "Quick Charge!" elsewhere on this site). Even with its hefty battery pack, the Phoenix SUT still offers a 1,000 pound payload capability. Phoenix is initially selling to fleets because that's where the math works out. Since it's a certified EV, the State of California provides some pretty massive incentives...enough to make it possible to sell a vehicle with $75,000 worth of batteries for $45,000. Of course, there is an expectation that costs will come down as the project moves along and battery prices diminish. " End quote Isn't this the bettery we have been longing for?
