Researchers create rechargeable, biodegradable batteries that run on sugar

Rechargeable, energy-dense bio-batteries running on sugar might be powering our electronic gadgets in as little as three years, according to a US team of scientists. The battery, created by the group of Y H Percival Zhang, an associate professor of biological systems engineering at Virginia Tech, can convert all the potential chemical energy stored in a sugar into electricity.

Researchers at Virginia Tech have developed a battery that runs on sugar and could one day replace traditional batteries with ones that are cheaper, refillable and biodegradable. Other batteries that are powered by sugar have been developed before but scientists say this one has an unmatched energy density, which enables it to run far longer before needing to be refilled. These new sugar-based batteries could run smartphones, tablets and video games in three years, according to Y.H. Percival Zhang, an associate professor of biological systems engineering at Virginia Tech.
