| Future energy Renewables, fuel cells, hydrogen, and efficiency Altairnano power play: I wonder if this battery is for real. "Altairnano - a relatively small public company [claims to produce] a battery that could power an electric vehicle
hundreds of miles, charge in 10 minutes, and have a service life of 20
years or more.. The secret, according to Gotcher, is nanotechnology, and
Altairnano's selection of nano-structured lithium titanate as a
framework for its battery, branded NanoSafe™. Because the storage
compartments are so small, the battery can store a lot of lithium ions.
And the titanate material used in the nanostructures enhances battery
cycle life, and gives it an extraordinary service life, he said., [claiming] more than 20,000 cycles with
little performance degradation, .. Altairnano says its batteries have been tested under
extreme conditions, including an operating temperature range of -50 to
plus 71 degrees Celsius. .. The battery pack can be charged at low voltage over long times, or charged at higher voltages quicker, Gotcher said. In a 10 minute or less charge, at least 480 volts at several hundred amps will be required, transferring 210 kW/h of energy to the battery pack. .. How would service stations of the future store the mammoth amounts of electricity required by electric vehicles? Altairnano's Gotcher says the company "hasn't really said a lot about that yet, but you'll see us come forward with information in the second quarter." Related news: Power company AES made a $3 million "strategic investment" buying 1.5% of Altairnano's stock. ZAP is building a Tesla-like roadster with its batteries. So is Phoenix Motorcars, which has contracted to deliver 200 utility trucks with these batteries to PG&E in June 2007: "Phoenix’s SUT can travel at freeway-speeds while
carrying five passengers and a full payload, the company claimed. The
SUT has a driving range of over 100 miles, can be recharged in less
than 10 minutes and has a battery pack with a lifespan of more than 12
years."
