This could change everything if it’s really more capacity than hype. Scientist at EEstor claim to have created a battery - a “parallel plate capacitor with barium titanate as the dielectric” or hypercapacitor. This is basically a battery that holds extremely high voltage charges in solid ceramic material. Quoting from www.TreeHugger.com with info obtained from a Toronto Star source within EEstor, this is what such a battery could offer:
The batteries fully charge in minutes as opposed to hours.
* Whereas with lead acid batteries you might get lucky to have 500 to 700 recharge cycles, the EEStor technology has been tested up to a million cycles with no material degradation.
* EEStor’s technology could be used in more than low-speed electric vehicles. The company envisions using it for full-speed pure electric vehicles, hybrid-electrics (including plug-ins), military applications, backup power and even large-scale utility storage for intermittent renewable power sources such as wind and solar.
* Because it’s a solid state battery rather than a chemical battery, such being the case for lithium ion technology, there would be no overheating and thus safety concerns with using it in a vehicle.
* Finally, with volume manufacturing it’s expected to be cost-competitive with lead-acid technology.
“It’s the holy grail of battery technology,” said my source. “It means you could do a highway capable electric city car that would recharge in three or four minutes and drive you from Toronto to Montreal. Consumers wouldn’t notice the difference from driving an electric car versus a gas-powered car.”
This could have major implications for the use of Electric Cars in specific and power storage in general. Although I’m not sure if that 5 minute charge would be possible in non industrial sectors. That amount of voltage or amperage is beyond the power mains connected to most homes. As some of the astute readers at www.treehuggers.com pointed out, perhaps the home solution could be slow charging 8 to 9 hrs, while one could go to a commercial “energy station” to get a quick 5 min full capacity charge.
I really hope this comes out for real and is not shelved or sabotaged for the sake of other corporate interest. The good news is the people behind this are extremely well funded. Also of note, Feel Good Cars of canada has an investment stake in EEStor and as - Gizmodo writes is committed to making this technology roadworthy by 2008. We really need clean energy and storage!
