Mobile phone battery made ​​from Sugar

Researchers from Virginia managed to find other alternatives to turn a smart phone without the use of electricity. Researchers successfully developed mobile phone battery with energy derived from sugar.

The team of researchers from Virginia Tech uses a chemical reaction to convert sugar molecules present on becoming an electrical power. This study originated from the extra energy that is obtained from a person when consuming beverages or foods with a high sugar content.

Researchers said, as quoted by Extremtech, on Monday, January 27, 2014, the sugar molecule is the energy density to be transferred easily and is cheap. The team of researchers from Virginia Tech managed to make sugar-based battery-power reaches 596 ampere hours per kilos. Power is 10 times higher than the material used batteries today, namely lithium.
A research team from Virginia Tech led by Y.H. Percival Zhang just developed a battery that runs on natural sugar that could replace conventional batteries within three years. The sugar battery is cheap, refillable, and biodegradable, and it could be used to power cell phones, tablets, video games and other electronic gadgets in the future. "Sugar is a perfect energy storage compound in nature,” Zhang said. “So it’s only logical that we try to harness this natural power in an environmentally friendly way to produce a battery."

The sugar battery combines fuel – in this case maltodextrin, a polysaccharide made from partial hydrolysis of starch – with air to generate electricity, and water is its main byproduct. “We are releasing all electron charges stored in the sugar solution slowly step-by-step by using an enzyme cascade,” Zhang said.

However unlike traditional batteries, the fuel sugar solution is neither explosive nor flammable and it has a higher energy storage density. The enzymes and fuels used to build the device are also biodegradable, and it can also be refilled, much like a printer cartridge. The cheap, biodegradable sugar batteries could power gadgets within three years.

Although successfully created, sugar-based mobile phone battery is still in prototype form that continues to be tested. In the future, most likely sugar-based batteries will be used to power mobile power. It was not clear when the mentioned year.. *** [EKA | FROM VARIOUS SOURCES | EXTREMTECH | INHABITAT]
