A battery that 'breathes' could power next-gen electric vehicles

Sales of electric vehicles (EVs) nearly doubled in 2013, but most won't take you farther than 100 miles on one charge. To boost their range toward a tantalizing 300 miles or more, researchers are reporting new progress on a "breathing" battery that has the potential to one day replace the lithium-ion technology of today's EVs.

Hitachi touts renewable friendly battery

Who knows how economical it might be, but the Japanese electronics and industrial giant Hitachi is moving toward marketing an energy storage system that could be a companion piece to renewable power generation – another sign of the growing interest in such products.

Scientists eye high-performance, long cycle-life lithium-sulfur battery

Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have demonstrated in the laboratory a lithium-sulfur (Li/S) battery that has more than twice the specific energy of lithium-ion batteries, and that lasts for more than 1,500 cycles of charge-discharge with minimal decay of the battery’s capacity. This is the longest cycle life reported so far for any lithium-sulfur battery.

Scientists invent self-healing battery electrode

Researchers have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell phones and other devices.

Turning a quarry into a battery with pumped hydro

Pumped hydro – a proven method of storing renewable energy for when it is needed – is a step closer to expanding in Wales with local approval of a 50-megawatt project.

Video: A battery made of wood?

A sliver of wood coated with tin could make a tiny, long-lasting, efficient and environmentally friendly battery.

Volvo tests electric roads

Battery conundrums continue to be a major road block for electric vehicles. They’re big, heavy, limit range, and although there’s less pollution coming out of an EV’s tailpipe, charging that monster battery still utilizes fossil fuels.

Scientists develop a high-efficiency zinc-air battery

Stanford University scientists have developed an advanced zinc-air battery with higher catalytic activity and durability than similar batteries made with costly platinum and iridium catalysts.

Electric car battery wants to support a 250 mile range

A new development in extending the range of electric cars on a single charge of a battery could soon mean range anxiety is more of a thing of the past. This interesting research breakthrough comes from Australia’s University of Wollongong (UOW).

The battery-memory device mashup

Resistive memory cells (ReRAM) are regarded as a potential, yet promising platform for future generations of computer memories.

A stretchable battery for flexible electronics

A newly-developed, stretchable lithium-ion battery could be used in the human body to power bionic implants and monitor brain or heart activity.

Elon Musk releases log of NYT 'fake' road test

As promised, Tesla CEO Elon Musk has released the log of the electric car that New York Times writer John Broder claimed last week had failed to perform.

Tesla CEO slams car review as 'fake'

A big row has broken out over a review of the Tesla all-electric car in the New York Times last week.

Scientists design imprintable, flexible lithium-ion battery

Scientists from South Korea have developed the world's first imprintable and flexible battery.

DARPA wants robots with more stamina

The trouble with robots, says DARPA, is that no matter how good they are, they have an annoying tendency to run out of juice. It's no good carrying heavy equipment halfway to where it's needed; even worse is a robot that gets halfway though disarming a roadside bomb.

Century-old battery technology given new life

Nickel-iron batteries, a rechargeable technology developed by Thomas Edison more than a century ago, have been largely out of favor since the 1970s - until now.

API glitch may explain fast-draining phone batteries

Almost a quarter of apps that contain Android's explicit power control APIs, or wakelocks, may have major battery-draining bugs.

Angry Birds drains your battery faster

Free mobile apps using third party services to display ads are draining users' batteries, researchers from Purdue University and Microsoft say.

This battery is powered by molten metals

Researchers at MIT say they have developed a new type of low-cost battery that could be the future of affordable energy storage systems.

DOE hub gets $120M to build a better battery

So, increasingly, we've got this whole renewable energy thing going on. But integrating all that new solar and wind power into the power grid remains a challenge.
