    Car Talk ^ | 7 Mar 12 | Jim Motovalli
    Envia has figured out how “to improve energy density at the anode and cathode and store more lithium.” In short, he claims to have doubled energy density and halved the cost of lithium-ion batteries. And he says that his breakthrough isn’t theoretical—packs are already built on an automotive scale and are being tested by automakers around the world. It’s impossible to verify all that, and Kapadia won’t tell me which automakers he’s working with, though GM is presumably one of them. Specifically, Envia says it has reached an energy density of 400-watt-hours per kilogram in auto-grade lithium-ion cells, and achieved...

    PROVIDENCE, RI, January 30, 2012, (LifeSiteNews.com) – Demonstrators from the Occupy Wall Street movement threw condoms on Catholic schoolgirls, refused to allow a Catholic priest to give a closing prayer, and shouted down a pro-life speaker at a Rhode Island right to life rally on Thursday, according to its organizer. The event marked the third time protesters associated with the movement have disrupted a pro-life meeting in a week. About two-dozen members of Occupy Providence hiked from Burnside Park to the 39th Annual Pro-Life State House Rally organized by the Rhode Island State Right to Life Committee on Thursday. Protesters...

    2011 saw huge advances in solar, wind and other renewable energy sources, and these advancements will continue into 2012. In fact 2012 could be the year that renewable energy sources start to seriously compete with traditional fossil fuels, at least that is the hope in the battle to reduce carbon emissions and our dependence on dwindling oil stocks. However a major problem with renewable energy sources is that they can rarely provide consistent power levels, due to a myriad of factors outside of human control. Eric Wesoff, an industry analyst with Greentech Media, explains that, “A wind farm only works...

    While the most common device for converting light into electricity may be photovoltaic (PV) solar cells, a variety of other devices can perform the same light-to-electricity conversion, such as solar-thermal collectors and rectennas. In a new study, engineers have designed a new device that can convert light of infrared (IR) and visible wavelengths into direct current by using surface plasmon excitations in a simple metal-insulator-metal (MIM) device. The researchers, Fuming Wang and Nicholas A. Melosh of Stanford University, have published their study on the new device in a recent issue of Nano Letters. “The greatest significance thus far is to...

    Toyota Motor has developed a secondary electric car battery that can last up to 1,000 km per charge, the Nihon Keizai Shimbun reported Monday. That is five times the energy storage capacity of existing batteries. Toyota came up with the prototype in collaboration with the Tokyo Institute of Technology and the High Energy Accelerator Research Organization. The new battery is based on a solid core and its simplified structure means it does not require fire-retardant materials. It eliminates the disadvantages of lithium-ion batteries, which are based on an easily heatable and combustible liquid core. Toyota plans to improve the battery...

    A group of gear heads from Croatia has produced a car designed to show that “electric vehicle” doesn’t have to mean “something my granola-eating neighbor drives.” Rimac Automobil, named for its founder, Mate Rimac, unveiled the Concept_One at the International Auto Show in Frankfurt. Designed as a sleek sports car it is powered entirely by batteries, and can, the company says, hit 62 miles per hour in 2.8 seconds, and reach a limit of 190 mph. The batteries carry 92 kilowatt-hours, or enough to power an average American home for three days -- or drive the car 372 miles, enough...

    A stretchy binder material that's compatible with existing factories could help electric cars and portable electronics go 30 percent longer. A stretchy binder material that's compatible with existing factories could help electric cars and portable electronics go 30 percent longer. One approach to the problem is to structure these anodes in a totally different way, for example growing shaggy arrays of silicon nanowires that can bend, swell, and move around as lithium enters and exits. This approach is being commercialized by Amprius, a startup in Palo Alto, California. But growing nanowires requires new processes that aren't normally used in battery...

    A Pittsburgh company says its battery has the long life and cheap cost needed to be practical for energy storage. Utilities need cheap, long-lasting ways to store the excess energy produced by power plants, especially as intermittent power from solar and wind farms is added to the mix. Unfortunately, the batteries available for grid-level storage are either too expensive or don't last for the thousands of cycles needed to make them cost-effective. A new battery developed by Aquion Energy in Pittsburgh uses simple chemistry—a water-based electrolyte and abundant materials such as sodium and manganese—and is expected to cost $300 for...

    A binding agent found in everything from ice cream to cosmetics could let lithium-ion cells hold much more energy. Lithium-ion batteries could hold up to 10 times as much energy per cell if silicon anodes were used instead of graphite ones. But manufacturers don't use silicon because such anodes degrade quickly as the battery is charged and discharged. Researchers at the Georgia Institute of Technology and Clemson University think they might have found the ingredient that will make silicon anodes work—a common binding agent and food additive derived from algae and used in many household products. They say this material...

    A Japanese research group has developed a solid state lithium battery that appears to perform just as well as conventional liquid lithium ion batteries. The group has published their results in Nature Materials and claim to have found a solid electrolyte that performs on a par with current liquid technology, and does so over a much broader temperature range and because it’s solid should be more compact as well as less sensitive to physical damage and fire hazard. Lithium ion batteries are currently used in a wide variety of consumer electronics (and electric vehicles) due to their energy density, re-chargeability...

    DEER ISLE, Maine — Before May 17, Kacen Pedrucci was a normal 15-month-old boy. At his Deer Isle home, he was beginning to talk and was walking around happily, exploring his surroundings and putting things in his mouth as toddlers do. He always had a smile and a sweet disposition. One of his favorite books was The Lion King, which was a “talking book” — by pushing a button on the side of the page, jungle sounds could be heard. But for the last three months, Kacen has been at death’s door, in and out of doctors’ offices, emergency rooms...

    GM and Nissan tout systems to reuse the expensive battery packs. At $10,000 a piece, electric-car batteries are too expensive to throw out or recycle into scrap materials. And even after a decade of use, when they can't perform well enough to meet the vehicle's demands, they could still be valuable for other uses. Nissan and GM have both recently announced ways they might make some money from them. Many issues remain unresolved, not the least of which is whether the automakers would need to buy back the batteries from car owners, or whether dealers would simply lease the battery...
