Battery that self destructs in Water in 30 Minutes

A breakthrough invention in developing transient batteries has been developed:  a self-destructing battery that completely dissolves in water without leaving behind any trace. Researchers at Iowa State University have designed a one-millimeter-thick, five-millimeter-long and six millimeters wide battery that use typical lithium-ion technology. The transient battery is made up of eight layers, including an anode, a cathode and the electrolyte separator, all wrapped up in two layers of a polyvi...

Old laptop batteries could power slums.

Old laptop batteries still have enough life in them to power homes in slums, researchers have said. An IBM study analyzed a sample of discarded batteries and found 70% had enough power to keep an LED light on more than four hours a day for a year. Researchers said using discarded batteries is cheaper than existing power options, and also helps deal with the mounting e-waste problem. The IBM team created what they called an UrJar, a device that uses lithium-ion cells from the old batteries to ...

Battery-free pacemaker powered by the heart itself

Scientists are developing next-generation battery-free implantable pacemakers that may be powered by an unlikely source, the heart itself. The advancement is based upon a piezoelectric system that converts vibrational energy, created inside the chest by each heartbeat, into electricity to power the pacemaker. "Essentially, we're creating technology that will allow pacemakers to be powered by the very heart that they are regulating," said M Amin Karami, assistant professor of mechanical engineeri...

Stretchy, origami battery powers Samsung smartwatch

Stretchy batteries inspired by origami could power smartwatches and other wearable electronics. Newly introduced, stretchy origami-style batteries could power the wearable devices of the future, say researchers who have managed to power a Samsung Galaxy Gear 2 with a battery of their own invention. The lithium-ion batteries developed by a team from Arizona State University are capable of stretching to 150 percent of their natural size and of powering existing smartwatches. Scientists wo...

Harvard Scientists Make Solar Power Production More Efficient

Solar power could be increased tenfold without additional storage in the near future. A team of Harvard scientists and engineers demonstrated a rechargeable battery that could make storing electricity from intermittently available energy sources, like sun and wind which is safe and cost-effective for both residential and commercial use. Much of the nation’s energy policy is premised on the assumption that clean, renewable energy, such as wind and solar power, will require huge quantities o...

Amazing Batteries that Run on Any Liquid

A new, “organic” battery has been invented which generates a charge within 10 seconds and will last anywhere from two days to a week depending on the liquid. The world’s first chlorophyll organic battery has been invented by Chungpin Liao, a professor at the Graduate School of Electro-Optic and Material Science of National Formosa University in Taiwan. He claims that his battery can be filled up with almost anything, including water and urine, and it can provide electricity from two to sev...
