In order to develop this miniature super battery, researchers used the two -dimensional graphene layer to have only a single atom in the third -dimensional three -dimensional level. At the same time, the research team found that the use of a standard DVD burning technology can easily manufacture this new battery.

　　The traditional method of manufacturing micro -supercapacitors involves dense optical technology, but it is confirmed that it is difficult to manufacture low costs, so it is limited in the field of commercial applications. At present, based on the popular lighting DVD recording technology suitable for the public, graphene micro -capacitors can be created with only some traditional device costs. Using this technology, we use cheap materials for less than 30 minutes to manufacture more than 100 miniature super batteries on a CD. "

　　In order to make the super battery more effective, the placement of the two separation electrodes must maximize its surface area. This will enable super batteries to store more energy. The previous miniature batteries were stacked together as an electrode, which was a bit like sandwiches.

　　In the latest designed super batteries, researchers use the fork -fit model (similar to interwoven fingers) to discharge the electrode together. This will help to maximize the two electrode surface area, although this will also reduce the path that the ion needs to spread in the electrolyte.
