Researchers made 3D printing graphene airgel super-capacitor electrode

According to foreign media reports, researchers are using 3D printing, it has the highest charge storage per unit surface area electrodes for the supercapacitors developed. University of California, Santa Cruz (University ofCaliforniaSanta Cruz) and the US Department of Energy\’s Lawrence Livermore National Laboratory (US Department of Energy\’s Lawrence Livermore Natio nal Laboratory) is a research collaboration, 3D printed graphene aerogels to develop porous three-dimensional scaffold, wherein the manganese oxide load, can produce better super-capacitor electrode. 研究人员3D打印石墨烯气凝胶 制成超级电容器电极 ultracapacitor energy storage device may be used, as it only seconds to minutes charged very rapidly, even thousands of times by the charge through the bad, but also to maintain the storage capacity, it can be used to regenerate an electric vehicle many applications braking systems. However, while technological advances have to be more competitive in other applications, but has not been used in super-capacitor battery, because they remain in the same space less energy, and can not be charged as long as the battery. Researchers have previously demonstrated ultra-fast charging a supercapacitor electrode may be prepared using a 3D printed graphene airgel, a new study, the researchers graphene airgel was improved manufacturing a porous scaffold, a reload oxide manganese. Graphene supercapacitor device / electrode made of manganese oxide exhibits excellent stability through the bad, after 20,000 cycles of charge and discharge bad, but also to maintain 90% of the initial capacity.
