Working under a Small Business Innovation Research (SBIR) grant from the U.S. National Science Foundation, we reported the findings in the January 2014 issue of Nature Communications.
This breakthrough sugar-powered biobattery can achieve an energy-storage density of about 596 ampere-hours per kilogram (A-h/kg) — an order of magnitude higher than the 42 A-h/kg energy density of a typical lithium-ion battery. A sugar biobattery with such a high energy density could last at least ten times longer than existing lithium-ion batteries of the same weight. [Electric Bacteria Could Be Used for Bio-Battery ]
This nature-inspired biobattery is a type of enzymatic fuel cell (EFC) — an electrobiochemical device that converts chemical energy from fuels such as starch and glycogen into electricity. While EFCs operate under the same general principles as traditional fuel cells, they use enzymes instead of noble-metal catalysts to oxidize their fuel. Enzymes allow for the use of more-complex fuels (such as glucose), and these more-complex fuels are what give EFCs their superior energy density.
