Geeking out on electric motorcycles – a trip to the Zero factory

Regular readers will know I'm a bit of a fan of Zero's electric motorcycles – as the market leader in performance electric two-wheelers, Zero offers a glimpse into a future where gasoline engines feel frankly archaic. So I was very excited to score myself an invitation to come and visit Zero's head office and factory to see where the company is at, get to know the Zero team, and ride the company's entire 2015 range through the breathtaking mountain ranges of California. It was a great chance to talk about batteries, production lines, the 2015 Zero range and how America's fast-charge infrastructure is letting riders down. Read More

Kevlar-reinforced lithium-ion batteries shouldn't catch fire

By - January 28, 2015 2 Pictures
While lithium-ion batteries may outperform their older, lower-tech counterparts, they do have one drawback – occasionally, they catch fire. This can happen when fern-like metal structures known as dendrites form between the battery's two electrodes, causing a short circuit. Now, however, researchers at the University of Michigan have used Kevlar nanofibers to create a barrier between the electrodes, which is impervious to those nasty dendrites. Read More

A new type of glass could double your smartphone's battery life

By - January 18, 2015 1 Picture
The batteries inside our smartphones and laptops are fighting a losing battle when it comes to keeping these devices juiced up, but researchers from ETH Zurich have discovered a new type of glass material that could make a major difference: vanadate-borate glass. The glass can be used as an electrode material in lithium-ion batteries to almost double the amount of time they last between charges. Read More

Ammonia-based battery system to convert low-grade waste heat into electricity

By - December 7, 2014 2 Pictures
As modern power generation methods are designed to squeeze the most power from the least amount of fuel, engineers are constantly looking at techniques to improve efficiency. One way to achieve this is to scavenge waste energy left over from the production process to capture and convert low-grade heat into usable energy. In pursuit of this goal, engineers at Pennsylvania State University have produced an ammonia-based battery that not only captures and converts waste heat economically and efficiently, but is claimed to do so at a greater capacity than other similar systems.

New electrolyte to enable cheaper, less toxic magnesium-sulfur-based batteries

By - November 30, 2014 1 Picture
There's another promising contender in the race to supplant the dominance of lithium-ion and metal-hydride based batteries in the world of energy storage. New research from the Karlsruhe Institute of Technology's (KIT's) Helmholtz Institute Ulm (HIU) details the development of an electrolyte that can be used in new magnesium-sulfur battery cells that would be more efficient and inexpensive than the dominant types of batteries in use today.

Philae bounce on comet landing may cut mission short

By - November 13, 2014 8 Pictures
During Wednesday’s historic landing on comet 67P/Churyumov-Gerasimenko, the European Space Agency's Philae lander suffered a setback that may cut its mission short. Due to equipment malfunctions, the unmanned, washing machine-sized lander failed to secure itself to the surface of the comet. In the 1/100,000 gravity, Philae bounced back into space twice, eventually landing in a hole about a kilometer (0.6 mi) from its designated landing area, where its batteries may not be able to charge properly.
