Batteries have been around for more than 100 years, but today, in some remote or resource-limited areas, this kind of daily necessities we are used to are still luxury items. And the latest result to be announced at the 256th National Conference and Exposition of the American Chemical Society-a new type of paper-based bio-battery that relies on bacteria to generate electricity may be able to change this situation and bring low-cost new types to these regions energy. This new type of battery was developed by a research team from the State University of New York in the United States. The researchers printed a thin layer of metal and other materials on the surface of the paper as a substrate, and then placed the freeze-dried electricity-producing flora on the paper to make a paper-based bio-battery. When using, just apply water or saliva on the paper. Within a few minutes, these freeze-dried bacteria will be restored to life. While they are generating energy for themselves, the sprouting electrons will pass through the cell membrane and contact the external electrodes, thereby Battery powered. Because paper is breathable, researchers have worried that electrons sprouted by bacteria will be absorbed by oxygen before reaching the electrodes, which will affect battery performance. However, studies have shown that oxygen has little effect on battery performance, because bacterial cells are tightly attached to the paper fibers, and the fibers have quickly transferred electrons to the anode before the oxygen intervenes. As a biosensor material, paper has magical advantages, good flexibility, large surface area, and low price. Continuous innovation of structural engineering technology allows people to control the fiber diameter, smoothness and translucency of paper, laying a good foundation for the widespread use of paper in a new generation of electronic products. Paper-based batteries are generally favored due to their wide applicability, eco-friendliness, and low cost. The researchers pointed out that the new paper-based battery they developed is very low-cost, convenient to carry, and can be easily integrated into disposable electronic devices. Although it has not yet reached the level of actual use, the battery performance needs to be greatly improved, but this improvement It can be realized by stacking and connecting multiple paper batteries. The current shelf life of such disposable batteries is about 4 months. Researchers are thinking of ways to improve the survival rate and performance of freeze-dried bacteria, thereby extending the shelf life of batteries. Yes, paper can also be used as a battery substrate, and freeze-dried bacteria can move electrons to the battery. This battery is designed simply and cleverly. In resource-constrained areas, the combination of flexible and stretchable paper and cheap and easy-to-use bacteria becomes a 'golden partner.' Although paper-based batteries are temporarily unable to achieve the effects of ordinary batteries, if the shelf life and battery performance issues are dealt with, it will be a good cost-effective choice. Researchers break people's traditional meanings of batteries and dig into various brains to do research. The ultimate goal is to let these fantastic ideas show their talents in special regions and special moments, and make human life more beautiful. In the future, the technology zone may rely on bacteria to generate electricity. American scientists will develop a new type of bio-battery. ON Semiconductor supplies a comprehensive high-efficiency cloud power method. Germany has developed a method for fast charging of solid-state batteries. This fast-charging solid-state battery will be further improved. iFORWAY will launch a brand new The portable energy storage power supply with a large capacity of 41600mAh can be used for various household proximity switch loads.
