In breaking through the development of long-lasting batteries for smartphones and other gadgets, scientists have successfully created sugar bio-cells that completely convert sugar-based chemical energy into electricity. This bio-battery can achieve an energy storage density of about 596 amp-hours per kilogram, an order of magnitude higher than the energy density of 42 amp-hours/kilogram of typical lithium-ion batteries used in various tools.
"Sugar bio-cells, this high-energy density, may continue to be more than 10 times higher than existing lithium-ion batteries of the same weight," said Biosystems Engineer at Virginia Tech, commonly known as Virginia Tech, associate professor, Percival Valle. . Bio-cells are a new type of enzymatic fuel cell, ie an electro-chemical device that converts fuel, such as starch and glycogen, into electrical energy and converts it into chemical energy. "We demonstrated for the first time that the sugar of a bio-cell is completely oxidized, so we achieved near-theoretical energy conversion rates, no one ever reported," Zhang added. Sugar bio-cells are also less expensive than lithium-ion batteries and environmentally friendly.
