A close up of the solar cell created by the Trinity team - the dark hair can clearly be se...

Debate is good. Debate is healthy. Debate is currently raging after an article recently appeared on the UK's Daily Mail website announcing a revolutionary solar cell that's made using human hair. A group of teenage students from Nepal claim to have replaced expensive doped silicon used in conventional solar panels with cheap and readily available human hair to produce a cell capable of generating 9V (18W) of electricity. Curiosity got the better of Gizmag's Paul Ridden, who contacted one of the team to find out more.  Read More

The test vehicle into which researchers are integrating a redox flow battery

German researchers say a new type of electric vehicle battery that runs on electrolyte fluid can be recharged as easily as refilling a petrol tank. When the redox flow rechargeable batteries are low, the discharged electrolyte fluid can simply be exchanged at the gas station for recharged fluid.  Read More

Silicon nanotubes after ultrasonic treatment - inset is an expanded image of a single nano...

In news that could greatly extend the range of electric cars, researchers have shown that replacing the conventional graphite electrodes in lithium-ion batteries with silicon nanotubes can produce a battery that can store ten times more charge. The researchers developed a silicon anode that, aside from extending the range of electric cars, could also make gasoline-electric hybrid vehicles more efficient by allowing them to run in electric mode for longer periods.  Read More

It’s not only integrated circuits that look set to benefit from the use of graphene, the one-atom thick wonder material made up of a honeycomb lattice of carbon atoms. Researchers have discovered that adding graphene to titanium dioxide for use as electrodes in batteries improves performance over standard titanium oxide by a factor of three. This could pave the way for inexpensive titanium dioxide to replace the expensive, rare-earth metals or fire-prone carbon-based materials used in today's lithium-ion batteries.  Read More

Microcapsules filled with carbon nanotubes could be used to repair electronic circuits

Dropping an electrical device such as a mobile phone or laptop can prompt a few anxious moments as you rush to see whether your beloved device has survived the fall. Now researchers at the University of Illinois at Urbana-Champaign are working to make such incidents a little less distressing - they're developing a self-healing first-aid kit for electrical systems that could stop circuits failing and lead to safer, longer lasting batteries.  Read More

Algae blooms are unpleasant and unpredictable phenomena that arise quickly and strike seas and oceans, often causing serious problems to local ecosystems. But, in an effort to try and find a use for such algae, a research team from Uppsala University, Sweden, has recently managed to design a record-breaking "green" lightweight battery that is incredibly easy to produce and might just even out the environmental consequences of these blooms.  Read More

As part of man's ongoing quest to extract the greatest benefits from solar power, Salt Lake City-based company Ceramatec, the R&D arm of CoorsTek, has made what it believes to be a massive breakthrough in batteries for storing energy harnessed from the sun. The company is making impressive inroads on the prototype of a deep storage battery, the size of a small refrigerator, that safely operates at room temperature, consists of everyday materials, and can output household power at 2.5c per kWh. What’s more, Ceramatec says it will be cheap to purchase.  Read More

Panasonic EVOLTA batteries record - the longest distance covered by a battery-operated rem...

Panasonic has put its EVOLTA line of alkaline batteries to the test and set a Guinness World Record for the second time. Its little “bot that could”, named 'Mr Evolta', has successfully completed the "24 Hours of Le Mans” endurance challenge powered on two AA EVOLTA batteries, giving Panasonic boasting rights to “the longest distance covered by a battery-operated remote–controlled model car”.  Read More

Sony's new rechargeable batteries that use Olivine-type Lithium Iron Phosphate as the cath...

We cover our fair share of battery technology breakthroughs here at Gizmag, from lithium-sulfur batteries to NanoEnergy batteries. But it’s less often that we get to report on new and improved batteries actually hitting the market. So it was nice to learn that Sony has launched a new type of rechargeable Li-ion battery that promises an extended life span more than four times that of existing Li-ion batteries and can be charged to 99 percent of its full capacity in 30 minutes - approximately half the charge time of Sony’s current Li-ion battery line up.  Read More

The Solio H1000 hybrid is perhaps the most versatile solar charger on the market

Learning more about consumption levels and investing in a standby-saver or two to cut down on waste energy is a great way to start becoming more green in the home, but there are also ways to utilize renewable energy when you're out and about.  Read More
