Kia unveiled its 2015 Soul EV at this week’s Chicago Auto Show. Scheduled to go on sale in the third quarter of 2014, the compact hatchback will be Kia’s first EV sold in the US, initially in just a few states, including California, Oregon, New York, New Jersey and Maryland. Pricing will be announced closer… Read more »

CalBattery’s new SiGr anode material hopes to break the battery bottleneck
California Lithium Battery took advantage of national and local government programs so it could focus on its revolutionary silicon-graphene anode material. Now with EV, electronics, and energy storage customers lining up, it hopes to break the battery bottleneck. When you think about a bottleneck, you think about constriction – something that moves in a particular… Read more »
New anode extends the life of lithium-sulfur batteries
Many researchers are interested in lithium-sulfur batteries, because they can offer up to four times the energy density of lithium-ion chemistries. However, current lithium-sulfur batteries have a much shorter lifespan. In a paper published this week in Nature Communications, a team from the Department of Energy’s Pacific Northwest National Laboratory (PNNL) described a “hybrid” anode… Read more »
Leyden Energy’s Li-imide electrolyte and the rise of start-stop vehicles
Battery start-up Leyden Energy plans to profit from the forecasted groundswell at the bottom of the electrification ladder: start-stop vehicles The average person may see the trademarked Li-imide logo and rush to the nearest convenience store to try a tangy new soft drink. However, you, being a somewhat chemistry-savvy electric vehicle enthusiast, know that Li-imide’s likely… Read more »
AllCell Technologies launches new battery solutions for e-bikes and pallet jacks
AllCell Technologies presented a couple of new lithium-ion battery solutions at this week’s Battery Show in Michigan. AllCell’s Summit line of premium e-bike batteries is available as a stand-alone product for OEMs, retailers, and consumers. Summit offers both 36- and 48-volt versions and capacity options of up to 17 Ah. Its down-tube mounting location provides… Read more »
Multiphase cooling: CapTherm’s technology takes the heat off
Canada’s CapTherm Systems’ multiphase cooling technology could take the heat off of EV batteries and charging stations more efficiently, taking up less space using fewer materials while improving longevity and performance. Charged takes an early peek at this innovation before it goes commercial next year. If you’ve never dropped your smartphone 10 feet onto pavement,… Read more »
Australian researchers announce supercapacitor breakthrough
Researchers at Australia’s Monash University have developed a compact graphene-based supercapacitor device that lasts as long as a conventional battery, an advance with the potential to bring next-generation energy storage a step closer. Professor Dan Li of the Department of Materials Engineering and his team published their work this week in Science. Supercapacitors (SCs) are… 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 »
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.
Can phase change material mitigate thermal runaway in Li-ion packs?
(This article originally appeared in Charged Issue 6 – JAN/FEB 2013) AllCell Technologies’ new phase change thermal management material If you have spent time at any of the EV industry trade shows, you’ve probably heard the term thermal runaway. It refers to a chain reaction in which an increase in temperature causes further increases in temperature and uncontrollable… Read more »
