    The company says its new ‘Ludicrous’ P100D will be the ‘fastest car in the world’ Tesla Motors Inc. said it is offering its electric vehicles with a battery capable of going up to 315 miles on a charge, the first time a major auto maker has provided that much electric range in a vehicle. The company unveiled new versions of its Model S sedan and Model X sport-utility vehicle with 100 kilowatt-hour batteries; previously the largest battery size was 90 kwh. The upgrade—which Tesla executives said was made possible by increasing the energy density of its battery packs—will allow the...

    Aluminium ions are stored between layers of graphite when the battery is charged A new rival to the lithium-ion battery has been created that charges in under a minute and still performs almost perfectly after being recharged thousands of times. The new battery is based on aluminium instead of lithium, which should make it both cheaper and safer than their lithium-ion competitors. The U.S. team behind the aluminium-ion battery say that the technology could find its way into the home, help store renewable energy for the power grid and even power vehicles. The aluminium-ion battery is conceptually similar to the...

    Stanford University scientists have invented the first high-performance aluminum battery that's fast-charging, long-lasting and inexpensive. Researchers say the new technology offers a safe alternative to many commercial batteries in wide use today. "We have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames," said Hongjie Dai, a professor of chemistry at Stanford. "Our new battery won't catch fire, even if you drill through it." Dai and his colleagues describe their novel aluminum-ion battery in "An ultrafast rechargeable aluminum-ion battery," in...

    The dramatic rise of smartphones, tablets, laptops and other personal and portable electronics has brought battery technology to the forefront of electronics research. Even as devices have improved by leaps and bounds, the slow pace of battery development has held back technological progress. Now, researchers at UCLA's California NanoSystems Institute have successfully combined two nanomaterials to create a new energy storage medium that combines the best qualities of batteries and supercapacitors. Supercapacitors are electrochemical components that can charge in seconds rather than hours and can be used for 1 million recharge cycles. Unlike batteries, however, they do not store enough...

    Electric carmaker Tesla announced Friday it delivered a "record" number of vehicles in the first quarter, as it began more timely reporting of sales figures. The California firm started by tech entrepreneur Elon Musk said it sold 10,030 cars in the first three months of 2015. "This was a new company record for the most cars delivered in a quarter and represents a 55 percent increase over the first quarter last year," the company said in a statement. Going forward, Tesla said it would publish the number of new car deliveries within three days of quarter end. "We have decided...

    Author provides inside look at Argonne National Laboratory’s efforts to build a ‘super battery’ By Laura Alessio March 27, 2015 So secretive were efforts to create the first self-sustained nuclear reaction in 1942 that physicist Enrico Fermi and his Manhattan Project team quietly toiled beneath the stands of Stagg Field and communicated with each other in code.That breakthrough ushered in the nuclear age, but also led to the creation of the country’s first national lab, Argonne National Laboratory. Some 70 years later, with 20 countries racing to achieve another world-changing scientific shift—to design and build a better rechargeable “super battery”—Argonne...

    Researchers at the University of California, Riverside's Bourns College of Engineering have developed a novel paper-like material for lithium-ion batteries. It has the potential to boost by several times the specific energy, or amount of energy that can be delivered per unit weight of the battery. This paper-like material is composed of sponge-like silicon nanofibers more than 100 times thinner than human hair. It could be used in batteries for electric vehicles and personal electronics. Scanning electron microscope images of (a) SiO2 nanofibers after drying, (b) SiO2 nanofibers under high magnification (c) silicon nanofibers after etching, and (d) silicon nanofibers...

    Ectric cars are quick and quiet, with a range more than long enough for most commutes. If you want a car with extremely fast acceleration, the Tesla Model S is hard to beat. And, of course, electric vehicles avoid the pollution associated with conventional cars, including emissions of carbon dioxide from burning gasoline. Yet they account for a tiny fraction of automotive sales, mainly because the batteries that propel them are expensive and need to be recharged frequently. A better battery could change everything. But while countless breakthroughs have been announced over the last decade, time and again these advances...

    Startup Seeo has developed batteries that store far more energy than conventional ones, which could extend the range of electric cars. An experimental lithium-ion battery based on materials developed at a U.S. Department of Energy lab stores twice as much energy as the batteries used in most electric cars. If the technology can be commercialized, it could give affordable electric cars a range of over 200 miles per charge, says Hal Zarem, CEO of Seeo, a startup that’s working on the technology. Today the cheapest electric cars, which cost around $30,000, typically have a range of less than 100 miles....

    After a historic but awkward comet landing, the robot probe Philae is now stable and sending pictures - but there are concerns about its battery life. The lander bounced twice, initially about 1km back out into space, before settling in the shadow of a cliff, 1km from its intended target site. It may now be problematic to get enough sunlight to charge its battery systems. -- The key issue vexing controllers right now is the lighting conditions. Philae is receiving about 1.5 hours of illumination during every 12-hour rotation of the comet. This will be insufficient to top up its...

    A new kind of solar cell could store electrical energy without any help from traditional batteries, according to a new study. Researchers at Ohio State University, in Columbus, have developed what they're calling the world's first solar battery — a hybrid device that combines the energy-capturing abilities of a solar cell with the energy-storing capabilities of a battery. The new cell could lower the cost of harvesting renewable energy from the sun by as much as 25 percent, according to the researchers. [Top 10 Craziest Environmental Ideas] The key to the device's success is a mesh solar panel that allows...

    Reuters sources inside Nissan are saying the production of batteries inTennessee for the all-electric Leaf, which stimulus-subsidizing U.S. taxpayers backed with a $1.4 billion loan, could be eliminated. According to the report, at minimum there is sharp debate over whether the company will continue to manufacture electric vehicle batteries in-house or contract with an outside supplier. Nissan partner Renault, which has 43.4 percent shareholder ownership in the joint company, is said to be pushing for outsourcing battery production – possibly to LG Chem. None who revealed the information were identified for the Reuters story. “We set out to be...
