According to foreign media reports, researchers have developed a highly efficient prototype of a new biofuel cell that can use enzymatic proteins to obtain energy from sugar, which is theoretically closer to 100% efficiency. In the future, it will replace traditional lithium batteries to power mobile phones and other devices. Virginia Tech researchers have developed a highly efficient prototype of a new biofuel cell that can use enzymatic proteins to extract energy from sugar, which is theoretically near 100% efficiency. In the future, it will replace traditional lithium batteries to power mobile phones and other devices.
Researchers are trying to use sugar to power electronic devices.
The human body converts sugar into energy through metabolic processes, decomposing sugar into carbon dioxide and water. This bio-cell can also generate energy by trapping electrons generated during the decomposition of sugar. Because bio-cells use bio-materials, they are reproducible and non-toxic, which makes them promising alternatives to traditional batteries.
Virginia Institute of Technology researchers Percival Zhang and Zhiguang Zhu designed this new type of bio-cell, which can convert sugar directly into energy, which means that its output far exceeds the previous bio-cells and even exceeds the normal lithium ion. battery.
This new type of bio-cell relies on the enzyme protein to achieve such a high efficiency that it can almost extract the energy contained in the sugar molecule and produce carbon dioxide and water. The energy extracted from the previous bio-cell was only one-sixth.
Although this cycle can completely convert sugar into energy, it uses less enzyme than humans. Shelley Minteer, a bio-cell expert at the University of Utah, said: "It's very important to extract all the electrons with the least amount of enzyme protein. I think this is a great metabolic pathway."
Although the new bio-battery system means a major breakthrough in this area, it still needs to overcome many obstacles. Zhiguang Zhu explained: “So far we have faced some challenges. The battery life is still too short, and it can not be recharged.â€
