The main impediment to mass electric-car adoption is price, and the driving force behind that is the cost of lithium-ion battery cells. The performance of those cells improves at about 7 percent a year, give or take: Either the same cell costs 7 percent less after a year, or a carmaker gets 7 percent more energy capacity for the same price. Those... Silicon anodes to boost lithium-ion battery capacity within a few years

When it comes to materials with the most promise in automotive applications, carbon fiber and graphene each rank high on the list. Unlike graphene, however, real-world carbon fiber applications exist today—and they're helping automakers reduce the weight of cars coming tomorrow. There's one big, unfortunate, and somewhat ironic problem with... 
While lithium-ion cells have powered all but a handful of plug-in electric cars since 2008, carmakers have looked further down the road toward solid-state battery cells with an eye toward launching them sometime during the 2020s. On Monday, BMW Group and Solid Power announced that the two companies would partner in an effort to develop Solid... 
Over the past decade, advances 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... 
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... 
Electric vehicles aren't always associated with speed and performance, but researchers at North Carolina State University may have discovered a breakthrough to change those qualities inside their batteries. Of all things, water may hold the key to faster electric-car battery technology. Researchers compared two materials, a crystalline tungsten... 
The promise of flying cars has been around for decades, and companies continues to show off their interpretations of what the public may expect in the future. Lilium is one of many companies promising a world of efficient, speedy, and personal air transportation—and now the project has officially gone airborne. The company's VTOL (vertical... ![2016 Toyota Mirai - Quick Drive - Portland, July 2015 [photo: Doug Berger]](http://images.hgmsites.net/tmb/2016-toyota-mirai_100521497_t.gif)
Toyota's staunch, unswerving support for hydrogen fuel cells has astonished and aggravated many in the electric vehicle community. For some of them, the technology is at best an inferior solution—and at worst is fossil fuel-friendly vaporware, a Judas in Jesus's clothing, if you will. With Daimler's recent announcement that it would... ![James Dyson with digital motors [image: Dyson]](http://images.hgmsites.net/tmb/james-dyson-with-digital-motors-image-dyson_100531077_t.gif)
Just 18 months after its $90m acquisition of Sakti3, the British consumer-products company Dyson is taking a step back. Dyson has chosen to relinquish the patent rights that were the core intellectual property of the Michigan based start-up company. Its move demonstrates the high risk companies are willing to accept in order to be at the forefront... 
Battery-electric cars are being delivered in volume today, but planned hydrogen fuel-cell vehicles from major automakers are on a more gradual timeframe. This morning, General Motors and Honda jointly announced that the two companies would establish a joint venture to produce hydrogen fuel-cell systems for future products from each carmaker... 
The signals are now unmistakable: Toyota will offer a battery-electric car for sale in 2020. After a decade of condemning electric cars as suitable only for the smallest vehicles in around-town use, the world's largest car company is changing its tune. Yet another news story out of Japan has company executives suggesting that it has finally decide...
