3D printing graphene airgel supercapacitors can be made strong
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 of California Santa Cruz) and the US Department of Energy\’s Lawrence Livermore National Laboratory (USDepartment of Energy\’s Lawrence Livermore National 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.
Researchers have previously demonstrated ultra-fast charging supercapacitor electrode may graphene 3D printing gas condensate made of plastic, in the new study, researchers graphene airgel was improved manufacturing a porous scaffold, and then manganese oxide load. 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.
