A salty battery bath to combat EV range anxiety

The degradation of electrodes in lithium-based batteries has been a major inhibitor to their operating life, particularly when dendrites "growing" from these corroding electrodes short-circuit in the electrolyte. Australian researchers have found that pre-treating lithium electrodes in a special salt bath decreases the breakdown of the electrodes and boosts performance and battery life so markedly it could bring an end to range anxiety for drivers of electric vehicles.Read More

eO EV breaks nine minute barrier at Pikes Peak hillclimb

Though Rhys Millen won last year's Pikes Peak Hillclimb, he didn't meet all his goals. Millen made it clear he wanted to complete a run in under nine minutes, a feat only Sebastien Loeb had managed before, but the best his electric eO could manage was 9:07.222. This year he broke that barrier, but was beaten to outright honors by Romain Dumas in a petrol-powered Norma. Read More

Mercedes flags 500 km EV platform, wireless charging and a hydrogen hybrid

As alternative powertrains move towards the mainstream, there is increasing pressure to create versatile platforms capable of handling a range of propulsion systems without huge development costs on each individual model. Volvo has SPA, Volkswagen has MQB and now Mercedes has used TecDay in Stuttgart to announce a dedicated platform for pure electric cars, alongside plans for wireless EV charging and a hydrogen plug-in hybrid SUV.

US Army and Marine Corps PowerWalk into wearable battery trials

Development of piezoelectric and triboelectric generators that harvest the kinetic energy generated by movement has been gaining momentum over the past few years, and now the US Army and Marine Corps are taking the technology into the field. Vancouver-based Bionic Power will soon supply troops with its PowerWalk Kinetic Energy Harvester, a lightweight device worn around the knee that recharges batteries while soldiers walk.

Self-charging battery stretches over skin to power wearables

While we've seen promising prototypes of computers that conform to the contours of human wrists and forearms, the technology isn't quite ready for mainstream adoption yet. But this hasn't stopped one forward-thinking team of researchers from coming up with a new way to power these wearable electronics, developing a soft, millimeter-scale battery that can be stretched over the skin like a band-aid.Read More

Nissan EVs to join the grid in UK trial

Nissan has partnered with power company Enel to launch a pilot program in the UK allowing electric vehicle owners to sell energy from their car batteries back into the grid. As well as allowing EV drivers to make a bit of extra cash from their cars, Nissan sees the program as the first step towards using cars as mobile energy hubs. The announcement came alongside the launch of the xStorage home battery, which uses recycled Leaf batteries for home energy storage.Read More
