Although the shortcomings of lithium batteries are obvious, it still takes a certain amount of time to replace them, and scientists around the world are also busy looking for corresponding replacements. According to foreign media reports, the Karlsruhe Institute of Technology in Germany has produced a breakthrough graphene super battery that can be fully charged within 15 seconds. This is a hybrid battery pack that combines an ordinary lithium-ion battery and a supercapacitor battery developed by Skeleton (a start-up company in Estonia) to give full play to their respective advantages under collaborative work. Lithium batteries have a high energy density, which means that they can store a lot of energy, but their power density is often quite low, which means that their charge and discharge speed is relatively slow, so in this case, the supercapacitor Add, the static stored charge will pave the way for fast charge and discharge. It is reported that this battery can be charged and discharged at a higher speed (increased energy density), and can last hundreds of thousands of cycles without degradation. Scientists are currently preparing for commercialization, of course, this requires further testing of its safety.
