Sugar-powered biobattery has 10 times the energy storage of lithium: Your smartphone might soon run on enzymes

2014-01-21 20:01:17| Extremetech

As you probably know, from sucking down cans of Coke and masticating on candy, sugar -- glucose, fructose, sucrose, dextrose -- is an excellent source of energy. There is a reason why almost every living cell on Earth generates its energy (ATP) from glucose. Now, researchers at Virginia Tech have successfully created a sugar-powered fuel cell that has an energy density of 596 amp-hours per kilo -- or "one order of magnitude" higher than lithium-ion batteries. The energy is clean (water is the only waste product) and very cheap to produce.
