New York: In a breakthrough to develop long-lasting batteries for smartphones and other gadgets, scientists have successfully created a sugar biobattery that completely converts the chemical energy in sugar substrates into electricity. This biobattery can achieve an energy-storage density of about 596 ampere-hours (A/h) per kg – an order of magnitude higher than the 42 A-h/kg energy density of a typical lithium-ion battery used in various gadgets. “A sugar biobattery […]
