American researchers have developed a method to a supercondensator to build on the basis of nanolaagjes of hemp fibers. The natural material would be a good alternative to graphene.
Although graphene is an excellent base material for the manufacture of supercondensators, is the production of graphene complex and therefore costly. American researchers have looked for alternatives to graphene and arrived at hemp. According to the scientists can be of the bast of hemp, which is normally disposed of as waste is considered a simple and cheap way nanolaagjes be won.
The hemp fiber in the method for up to 24 hours is heated to 176 degrees. By the heating process arise extremely thin koolstoflaagjes. This can in supercondensators be used as the electrode, while an ionic liquid as the electrolyte standing.
The scientists claim that such a supercondensator a higher energy density than regular capacitors, and that she was also in a wider temperature range of application can operate. The energy density would be up to 12Wh per kilo amounts. Ultimately, hope to the scientists that developed supercondensator widely used can be, for example, in electric cars.
