| Improved supercapacitors for super batteries, electric vehicles Posted: 19 May 2014 09:25 AM PDT Researchers have developed a novel nanometer scale ruthenium oxide anchored nanocarbon graphene foam architecture that improves the performance of supercapacitors, a development that could mean faster acceleration in electric vehicles and longer battery life in portable electronics. |
| Lab shows powerful, possible next step in electric motors Posted: 19 May 2014 09:25 AM PDT Scientists have demonstrated electric motors or generators that eliminate rare earth metals. Typical motors are powered through the electromagnetic interaction between a rotor, which contains rare earth metals and rotates, and another part known as a stator, which is stationary but houses electromagnetic sources. The new solution, called a double-stator switched reluctance machine (DSSRM), has two stators, one on either side of the rotor, that cause an electromagnetic reaction that produces power. This approach produces significantly greater power and torque at a given size and weight than traditional motor technologies without the use of permanent magnets. |
| Liberating devices from their power cords Posted: 19 May 2014 09:25 AM PDT A new type of supercapacitor that can hold a charge when it takes a lickin' has been developed. It is the first "multi-functional" energy storage device that can operate while subject to realistic static and dynamic loads – advancing the day when everything from cell phones to electric vehicles will no longer need separate batteries. |
