PNNL's high performance zinc-polyiodide flow battery approaches the performance of some li...

A new redox flow battery developed at the Pacific Northwest National Laboratory (PNNL) more than doubles the amount of energy that this type of cell can pack in a given volume, approaching the numbers of lithium-ion batteries. If the device reaches mass production, it could find use in fast-charging transportation, portable electronics and grid storage.  Read More

Tesla home battery, which is currently produced for SolarCity's home energy storage system...

The same lithium-ion battery technology that powers Tesla’s electric vehicles will be used to develop a battery for the home, according to a statement by CEO Elon Musk during a recent conference call with analysts. The batteries would be used by homes and businesses to store excess energy generated from solar panels during the day, and drawn from at night when panels sit idle.  Read More

Researchers at the University of California, Riverside say they have found a way around th...

Researchers at the University of California, Riverside (UCR) have developed a silicon anode for lithium-ion batteries that outperforms current materials and gets around previous issues that would cause the battery to be inefficient and quickly degrade (or even fail catastrophically) with use. As the researchers focus on scaling up production, the advance could pave the way for higher-performance electric vehicles, electronics and all-around portable power.  Read More

The way snails control the growth of their shells has provided inspiration for a new appro...

In an ongoing effort to improve the performance of lithium-ion batteries, scientists have looked to the techniques that snails use to control the growth of their shells. This biological inspiration, combined with a peptide found to bind very effectively with materials used to make cathodes, has potential for making lighter and longer-lasting batteries.  Read More

A new line of partially recycled alkaline batteries from Energizer could pave the way to g...

Energizer has announced a new line of high-performance AA and AAA alkaline batteries that are in part made by recycling old cells, in what's claimed to be an industry first. Although currently only four percent of the battery comes from recovered materials, the plan for the company is to grow that percentage tenfold over the next 10 years and eventually use recycled materials in all its future cells.  Read More

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

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

Vanadate-borate glass could almost double the amount of time lithium-ion batteries last be...

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

A study by IBM researchers has revealed that many discarded laptop batteries have the potential to provide enough power to keep the lights running in homes in poorer countries around the world. The India-based team conducted a small study to test the viability of the idea, with work now focused on streamlining a prototype system.  Read More

Engineers at Penn State University have produced an ammonia-based battery that captures an...

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.  Read More
