Last September, Nevada governor Brian Sandoval signed a bill granting various tax breaks and incentives to Tesla Motors for construction of its massive battery "gigafactory" outside Reno. Now, photos taken yesterday show that work on the site--empty desert land less than a year ago--is well...

Graphene could have a major impact on green cars.

Lead is terrible stuff: damaging to humans in even small quantities, and persistent if it's improperly disposed of.

A new startup looks to break into the electric-car battery business.

VW CEO Martin Winterkorn showed interest in solid-state batteries during a recent speech.

The formula is simple: Put three battery and auto-industry experts in front of a camera, ask them a few leading questions, and let them debate. That's exactly what the Autoline Network did three weeks ago; the resulting 27-minute video is a must-watch for any electric-car enthusiast. The three...

General Motors took the wraps off its second-generation Voltec electric-drive system this morning that will power its 2016 Chevrolet Volt range-extended electric car. Company executives declined to give specifications for power of the two electric motors, the range-extending engine, or range of the...
