Recently, scientists at Rensselaer Polytechnic Institute announced that they have developed a "body fluid battery" that can generate electricity using electrolytes in body fluids. This signifies that we are one step closer to the true launch of "bioenergy batteries". Scientists hope that "bioenergy batteries" can generate electricity from body fluids or other organic compounds excreted by the human body, such as tears and urine.
This battery is not only as thin as a piece of paper, but in fact it is actually a piece of paper. Because 90% of the material in the battery is plant fiber-it is an indispensable raw material in traditional papermaking, so it is widely present in various papers and paper products. The remaining 10% of the material is oriented carbon nanotubes, its main role is to conduct electricity, and because of its presence, this battery appears black. These carbon nanotubes are embedded in the gaps of paper fibers, and the finished product becomes nanocomposite paper. One of the developers said that this battery looks like paper no matter how it looks, feels or picks up.
This kind of battery using nanotechnology has a special design like paper: light and thin, scalable. Moreover, since the energy source is electrolytes in body fluids (which can be replenished by eating), it is very suitable for use in medical devices. It can be used even if it is separated from the human body, you only need to immerse it in the ionic liquid containing electrolyte.
Good scalability is also one of the advantages of this battery. The R & D staff said that after the battery is put into mass production in the future, it can be made into a long strip like paper, and then the user can cut it into the desired shape. This nano-compliant material still maintains its original performance even after being processed through perforation and folding, and because it is light and thin, it will not be uncomfortable even if it is implanted in the human body. Therefore, it is used in cardiac pacemakers, prostheses, etc. Appliances are very good.
In addition, the applicable temperature of the electrolyte solution is wide. It is not as easy to condense or boil as water, and can maintain a liquid state in the range of -100 degrees to 300 degrees Fahrenheit. In other words, it can still be used normally under extreme temperature conditions. In this way, it can also become the perfect energy source for vehicles such as cars and airplanes, because they require batteries that are both thin and light, and heat and cold.
But the researchers say that the application of this battery is far more than that, it can even become a high-energy battery, or a high-voltage capacitor. It can be used in devices that require huge, explosive energy. It can be said that this battery has unlimited potential.
Traditional batteries will leave a lot of contaminants after use, but this kind of battery will not. Because the raw materials it uses are basically free of harmful chemicals, it is very environmentally friendly. Of course, it will take some time before this high-tech battery is actually put on the market. The research team is working hard to improve the efficiency of this battery, and is committed to developing the best production methods to bring this battery to the market as soon as possible. (
