Silicon anodes to boost lithium-ion battery capacity within a few years

Prototype production of battery modules for BMW Group’s fifth-generation electric powertrainThe 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...

Carbon fiber from plants close to carbon-neutral? Scientists hopeful

McLaren Monocage II carbon fiber monocoque structureWhen 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...

Why better-battery startups fail in the US and how to fix it: report

Flat lithium-ion battery back for next-generation Mercedes-Benz electric carsOver 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...

Better alkaline batteries, made rechargeable, to power electric cars?

Tesla Motors - Model S lithium-ion battery packAlkaline 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...

Could water be the secret to faster electric-car battery technology?

Prototype EVgo 350-kw fast-charging station Fremont, CAElectric 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...

Lilium all-electric vertical takeoff and landing jet: first flight video

Lilium VTOLThe 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...

Dyson walks away from Sakti3 solid-state battery patents

James Dyson with digital motors  [image: Dyson]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...
