EEStor claims that its system, called an electrical energy storage unit (EESU), will have more than three times the energy density of the top lithium-ion batteries today. The company also says that the solid-state device will be safer and longer lasting, and will have the ability to recharge in less than five minutes. Toronto-based ZENN Motor, an EEStor investor and customer, says that it's developing an EESU-powered car with a top speed of 80 miles per hour and a 250-mile range. It hopes to launch the vehicle, which the company says will be inexpensive, in the fall of 2009. At the EESU's core is a ceramic material consisting of a barium titanate powder that is coated with aluminum oxide and a type of glass material.
EEStor claims momentum is building and that they'll start coming out with information about the company's progress on a "more rapid basis." Plans are also under way for a major expansion of EEStor's production lines. "There's nothing complex in this," he says, pointing to his past engineering days at IBM. "It's nowhere near the complexity of disk-drive fabrication."
If EEStor is successful, their technology could be used to extend the range, capacity or other performance metrics of electric planes. Current electric planes have a range of about 100 miles. Tripling range would be 300 miles. Alternatively a shorter range with more passengers is also possible. 4 people instead of two people at about 100-150 mile range.
Hybrid electric planes can go 720 miles.
