World’s 3rd largest battery firm may ally with VW for electric cars in China
Many automakers have announced they will electrify entire vehicle portfolios in the years to come. With more electrified cars on the road, battery production will become increasingly more important. Adding to the positive outlook for lithium-ion cell makers is Volkswagen's potential partnership with CATL (Contemporary Amperex Technology Company... 
Over the past decade, advances in battery technology have progressed steadily, but not quite as quickly as impatient electric-car advocates might like. With electric cars and plug-in hybrids fast becoming part of every carmaker's lineup, durable, less expensive, and higher-capacity batteries are more important than ever. Yet despite growing... 
Daimler, the parent company of Mercedes-Benz, is expected to announce that it will invest up to $1 billion to build electric SUVs and batteries in and around its Alabama assembly plant. The plans, first reported reported Thursday in The Wall Street Journal (paywalled), represent a major expansion of electric-car manufacturing in the U.S. So far... ![Mercedes-Benz EQ electric car concept [photo: Axel Harries]](http://images.hgmsites.net/tmb/mercedes-benz-eq-electric-car-concept-photo-axel-harries_100597897_t.gif)
The first vehicle in history considered to be an automobile was the Benz Motorwagen of 1885. It was also the first vehicle from an automaker that has been around for the duration of the industry: we know it today as Mercedes-Benz. In other words, the company has been building cars for 132 years. DON'T MISS: Mercedes to launch 10 electric cars by... 
Renault hasn't tackled the home-energy storage market to the degree its alliance partner Nissan has, but it has found another use for "second-life" batteries. The French brand has worked with UK-based Connected Energy to install two electric-car DC fast-charging stations powered by second-life batteries. Once the energy capacity of lithium-ion... 
General Motors has informed "a few hundred" owners of 2017 Chevrolet Bolt EV electric cars that their cars could suffer from a problem with the lithium-ion battery pack that could cause it to fail without warning. The cars were among the very earliest Bolt EVs produced for public sale, so are likely concentrated in California and perhaps Oregon... 
Relatively few people focus on it, but the huge Japanese electronics company Panasonic is a minority shareholder in electric-car maker Tesla. The deal dates all the way back to November 2010, the same year that Tesla completed its initial public offering after Toyota took a stake in the company and sold Tesla its Fremont assembly plant in... 
Alkaline batteries have been a staple energy source for decades, but their potential has been capped by their chemical properties. Notably, alkaline batteries cannot be recharged, which means their application is often limited to single usess in small devices such as flashlights and remote controls. An alkaline battery finding its way to an... 
The report that Toyota is planning an electric car with a solid-state battery for 2022 has led some fans and advocates to suggest huge new leaps in electric cars are imminent. The 2011 Nissan Leaf had an EPA-rated range of 75 miles combined; the comparable figure for a 2017 Chevrolet Bolt EV is 238 miles. That's remarkable progress, and clearly... 
Fisker's promise to bring advanced, solid-state graphene cells to the battery pack of its upcoming Emotion electric car is officially dead. Automotive-grade graphene batteries have yet to be perfected, but Fisker was poised to become the first company to utilize the technology. The batteries provide greater range and shorter charging times, but... 
As rules to boost fuel economy and lower carbon emissions in vehicles around the world continue to stiffen, acronyms like EREV, CNG, and MPGe are becoming more and more common. Ever wonder what they all mean? This glossary is your chance to enter a veritable Twilight Zone of terminology--and find out, say, whether a PZEV is related to a PHEV... 
The 2018 Nissan Leaf will likely be revealed within the next three months, but more than 100,000 older Leaf electric cars are still silently in use on U.S. roads. Some of them, especially the lowest-range cars from the two earliest model years (2011 and 2012), have started to see significant battery capacity degradation. That was the case with... 
It's one of the most common questions among electric-car buyers: what happens if the battery fails? The answer is that all electric-car batteries are warranted against failure for either 8 years/100,000 miles or 10 years/150,000 miles, depending on which state you live in. The followup is often: OK, then, what does a battery cost once my car's out... 
With more plug-in electric vehicles on the road today than ever, automakers are working to solve an impending issue: what to do with used lithium-ion batteries. Once the batteries are no longer suitable to power vehicles, automakers must recycle or repurpose them. Now, through a partnership with The Mobility House, the Renault Nissan Alliance is... 
Ten years ago, lithium-ion cell maker A123 Systems was a hot startup and a much-publicized company. This author, in fact, profiled the company for IEEE Spectrum in the technology magazine's September 2007 issue. The six years that followed proved enormously painful for the Massachusetts company, however. DON'T MISS: A123 Systems To Recall... 
The costs and prices of electric cars are endlessly debated, not only among owners and advocates but within the industry itself. The cost per kilowatt-hour of electric-car batteries is closely held, with a few notable exceptions. One of those was the statement by GM product chief Mark Reuss that the company pays $145 per kilowatt-hour for the... ![StoreDot shows fast-charging battery cell, Cube Tech Fair, Berlin [via Periscope: Gruendermetropole]](http://images.hgmsites.net/tmb/storedot-shows-fast-charging-battery-cell-cube-tech-fair-berlin-via-periscope-gruendermetropole_100606667_t.gif)
It's one of the Holy Grails for battery researchers and electric-car advocates alike: a battery that could recharge in the same amount of time as it takes to stop for gasoline. Some of that can be provided by charging at higher rates, as Porsche's proposed 800-volt system for 15-minute fast charging would. But most of the change has to come deep... ![Tesla Model S lithium-ion battery pack in rolling chassis [photo: Martin Gillet via Flickr]](http://images.hgmsites.net/tmb/tesla-model-s-lithium-ion-battery-pack-in-rolling-chassis-photo-martin-gillet-via-flickr_100481091_t.gif)
Perhaps the biggest question in buyers' minds over electric cars is how long the batteries will last. Most new-car buyers have mobile phones whose batteries have only lasted a couple of years, perhaps less. Even as electric-car battery packs are warranted against outright failure for eight or 10 years, how much degradation should owners... ![2011 Nissan Leaf electric car after battery-pack replacement [by owner Tim Jacobsen, Concord, CA]](http://images.hgmsites.net/tmb/2011-nissan-leaf-electric-car-after-battery-pack-replacement-by-owner-tim-jacobsen-concord-ca_100599982_t.gif)
In designing, testing, and producing the Nissan Leaf, the first modern electric car sold in volume, Nissan made a design decision that some other companies didn't. It chose not to build an active thermal-conditioning system (otherwise known as cooling) into its battery pack. Instead, it relies on ambient air to shed heat—which got the maker...
