What’s built on the same platform as the Volt, has the same powertrain, and costs more than twice as much? The 2014 Cadillac ELR plug-in hybrid, which will go on sale in January with a sticker price of $75,995, including destination charges. GM plans to produce only a limited number of the luxury sedans, and… Read more »

OXIS Energy bets on lithium-sulfur
Though it may have a stinky reputation, sulfur could set EVs on the path to total ICE replacement if energy-dense, low-weight lithium-sulfur batteries become the norm. British-based OXIS Energy is banking its business on it. If American clean energy industries are to take full advantage of the emerging lithium-sulfur (Li-S) battery chemistry, they just may… Read more »
Ultracapacitors creep into automotive
Maxwell looks to leverage its early ultracapacitor experience into a ubiquitous, low-cost, high-volume complement to batteries. Power sources like internal combustion engines and advanced battery packs work great as continuous suppliers of energy. But during the highest peak loads, both sacrifice efficiency attempting to meet the power delivery demands. And pushing these devices to their… Read more »
KAIST discovers method to extend Li-air battery life
Researchers from the Korea Advanced Institute of Science and Technology (KAIST) have discovered a means to extend the lifetime of lithium-air (Li-air) batteries, a technology that offers the promise of higher energy densities than those achievable with conventional lithium-ion batteries. They report their findings in the February issue of the journal ChemSusChem. Li-air batteries are… Read more »
Oak Ridge researchers give solid Li-ion electrolytes a new spin
Their novel approach offers an advantage in terms of safety and also results in a broad (5 V wide) electrochemical window.
December 2012: best month ever for plug-in vehicle sales
Even as the mainstream press continues to insist that no one is buying plug-in vehicles, December set a new monthly sales record, as the three market leaders continue to battle for the top spot, and a couple of new entrants posted impressive early results. The Chevrolet Volt rebounded from a weak November to sell 2,633… Read more »
