Tencent science - According to reports in the science news website, at present, a research team at the university of Toronto newly developed a kind of battery, energy can be stored in the form of biological. The latest study, published in the July 14 issue of the journal of advanced functional materials.
This new type of battery is similar to many commercially available in the lithium ion battery, but there is a difference, it USES vitamin B2 flavin as cathode, in this part of the stored electric current, when connected to a device emit the current.
The authors, the department of the university of Toronto, DeWitt - plug floors (Dwight Seferos), said: "we have studied the natural material properties for a period of time, look for complex molecular structure can be used for a wide range of consumer electronics products. When you carefully analysis of the existence of natural complex structure, will use less time to make new materials."
Although developed biological derivative battery parts before, but this is the first time using polymer - long chain derived from biological particles, as a kind of electrode, nature can make the battery energy storage in the vitamin of plastic material, its cost is low, and it's easy to make, does not use harmful to the environment pollution in the process of metal, such as cobalt.
Study co-author, the department of the university of Toronto, Taylor thorne (Tyler Schon) said: "with the right materials, after many test reaction, in many ways, it looks like a failure, but the whole process of unremitting efforts and gained some important discoveries." Scientists discovered by accident when testing a variety of long-chain polymers of vitamin B2 flavin, this is a special kind of side base polymer, molecular attached on the "backbone" of long chain molecules.
Lithium ion batteries and flavin together, will be given a 125 mAh/g, 2.5 volts, the researchers point out that in a device using lithium metal as the anode, the polymer as the cathode. At the same time, we demonstrate that the small molecule riboflavin is higher than that in the material performance, it is found that the highest energy of biologically derived polymer cathode.
Every time, "said Dr Plug floors vitamin B2 can accept two electrons, so it is easy to charge, have a higher capacity than other molecules."
