Mention the term "alkaline battery" and folks of a certain generation will remember the old Eveready battery commercials with actor Robert Conrad daring the viewer to knock the battery off his shoulder. Very macho. Now, alkaline has moved from manliness to money-saving, as the fine folks at Princeton University have been granted almost $1 million from the US Department of Energy to develop alkaline batteries suitable for electric-vehicle use, Princeton Patch reports.
Lithium-ion batteries have two big hurdles to climb if they're going to power millions of plug-in vehicles – they're too expensive and their reliability has been called to question. For next-gen li-ion batteries to make it, there had better be a cheap and plentiful component. How about rice husks?
Once the epitome of EV cool, the Tesla Roadster has kind of taken a back seat to the new electric vehicles in the market it helped spawn. Turns out, even in the background, the Roadster has things to teach us. Or, at least it does to the experts at Plug In America who recently took a closer look at the EV's battery pack.
Delivery companies like FedEx and UPS espouse the virtues of lithium ion batteries, but only when the packs are inside hybrid or electric vehicles. Delivering li-ion batteries is another story.
Perhaps this is where some of that excess battery manufacturing capacity in Smyrna, TN will be used. Nissan announced a new battery replacement program for the all-electric Leaf today at a cost of "approximately $100 per month." The offer is in addition to the standard Leaf battery warranty that already covers the battery for against defects for eight years or 100,000 miles (and was upgraded late last year to cover capacity loss for five years or 60,000 miles).
Earlier this year, Malta-based Silex Power promoted a concept electric vehicle that could go from San Francisco to Portland on a single charge. Not content with that claim, the company is now saying it's ready to make a high-powered electric charger that could fully recharge a top-of-the-line Tesla Model S in about the time it takes to play a hit single.
Sometimes, you have to go across the border to get the skinny on what's happening in the US. For example, did you know GM might be testing electric cars with batteries that have about three times the energy density of today's EV?
Tesla Motors turned the "penny wise, dollar foolish" axiom on its head by staking its lithium-ion battery technology on a more expensive and more complex layout than its competitors, according to Tesla Chief Technology Officer JB Straubel in an interview with Bloomberg News.
It's official: A123 Systems Inc. is passing through its final phase. The bankrupt lithium ion battery maker, now going by the name B456 Systems Inc., has won court approval for its plan to exit bankruptcy that pays off creditors from proceeds gained by selling off virtually all of its assets.
There are already lithium-ion batteries in some Toyota vehicles (the Prius Plug-in Hybrid, the RAV4 EV and the European Prius+, for example), but the company's standard bearer – the non-plug Prius hybrid – still relies on nickel metal hydride (NiMH) cells. But, the future belongs to li-ion, and that's why Toyota will soon increase its production of the higher-energy-density batteries sixfold with an eye to putting them into the Prius at an unspecified point in the future, according t
If the US would like to stop importing 80 percent of its lithium, mainly from China, and if Bolivian sources don't come through, it looks like there is a big domestic opportunity: Wyoming. Having an ample domestic supply would bring down the price of lithium, which could mean electric vehicles would become more cost competitive.
Imagine recharging a Nissan Leaf from a standard 110-volt outlet in, say, oh, about a minute. Far-fetched, sure, but at least one research facility thinks it has a lead on making lithium-ion batteries that can recharge 1,000 times faster than current ones.
Electrovaya, the Canadian lithium-ion battery maker, is ready to go full speed ahead on battery production after cutting its output and improving its technology.
Expert: Unsafe lithium-ion batteries mean EV sales predictions were off by "more than a factor of 10"
The mystery of potentially dangerous lithium ion batteries continues to hang over sales of vehicles using this technology. Experts who recently testifyied before the US National Transportation Safety Board (NTSB) said that failure of the technology has slowed development of electric cars and other applications of the batteries.
With keywords like lithium-ion batteries, "thermal runaway" and Elon Musk, had we not read any further, we would have figured this story was some disastrous news about Tesla Motors. Instead, it's about airplanes. Specifically, Boeing's new Dreamliner.
The weather may have cooled off in the Valley of the Sun, but not the sentiments of some Phoenix-area owners of Nissan Leaf electric vehicles.
Nissan has announced that it is going to offer a bit more security to Leaf owners than soothing words and lemon buybacks when it comes to degrading battery capacity. In a note published on My Nissan Leaf (and available below), Andy Palmer, Nissan's executive vice president, writes about a new enhancement to the "warranty coverage of the battery system that powers the Nissan Leaf."
Battery electric and plug-in hybrid electric vehicles with lithium-ion batteries are putting more and more odometer miles on every day. After two years on the market, some of these cars have up to 30,000 miles on them. That's good and all, but there's more to be done to prepare for the long term. General Motors, for example, tested the Chevrolet Spark EV batteries for over 200,000 hours. Ford, too, is looking way down the road, testing what life will be like for li-ion batteries after 10 years a
To some, a recent offer by Tesla Motors to replace batteries in its Model S all-electric sedan for under $150 per kilowatt hour reflects an extremely futuristic view of improving EV technology. To Plug In Cars, though, the offer is more a reflection of the age-old "bird in hand" axiom.
