Tesla Debacle Highlights Need For New EV Battery Technology

EVs sure have been getting a bad rap: this weekend’s New York Times hit piece on the Tesla Model S’s inability to sustain an adequate charge and last year’s scrutiny from the National Highway Traffic Safety Administration after a Chevy Volt fire at the test facility have sparked doubt and criticism about cars powered by lithium-ion batteries.

The Li-ion batteries in these cars were heralded as the beacon mobility’s future–green, safe, reliable.

But these technologies are constantly evolving, and the deficiencies at this current development stage aren’t that surprising (you remember nickel-metal hydride batteries and the EV1?).

The Li-ion battery, of course, has long been hailed as the best EV battery around, but its flaws at enduring heat and providing range have spurred innovators to seek alternatives.

Sure, a Li-ion battery with a range of 40 odd miles is going to get you around town on any given day, but what about your Griswold-esque family vacation or your D.C.-to-New York go-for-the-jugular odyssey? Can we conceive of the 500 mile road trip powered by a battery?

Electric cars are only just arriving in any main stream capacity, but already auto makers are having to look at what’s next.
