Research proves that new sugar bio-batteries will be 10 times more durable than traditional lithium-ion batteries

Tencent Science News According to foreign media reports, at present, the latest scientific research states that a sugar bio-battery concept can completely convert the chemical energy in sugar into electric current. The latest research report was published in the journal Nature Communications. The energy storage density of sugar bio-battery is about 596 ampere-hour/kg (Ah/kg). In contrast, the energy storage density of lithium-ion batteries is 42 Ampere-hour/kg. This means that sugar bio-batteries can continue to be used for at least 10 times longer than existing lithium-ion batteries of the same weight. Sugar bio-cell is an enzyme-catalyzed fuel power cell (EFC), a biochemical device for generating electricity, which can convert the chemical energy in glycogen and starch into electric current. At the same time, enzyme-catalyzed fuel power cells use the same working principle as traditional fuel power cells. They can use enzymes instead of precious metal catalysts to oxidize their fuel. Enzymes can use more complex fuels, such as glucose. At the same time, more complex fuels can make enzyme-catalyzed fuel power cells have a stronger energy density. For example, in the synthesis of hexose, each glucose molecule can release 24 electrons under nearly complete oxidation. However, the hydrogen molecule used in traditional fuel power cells only releases 2 electrons under oxidation. Zhu Zhiguang, a senior scientist at Cell-FreebioInnovations, declared that our research team was not the first to propose the use of sugar as a fuel for bio-cells. However, we have confirmed for the first time that the complete oxidation process of sugar-bio-cells can convert chemical energy into electric current One result.
