Opened the way to accelerate batteries for 3 times

Every year the power of mobile devices increase, but the batteries for them have not kept pace. So is considered the norm to have an outlet and a pair of powerbank to boot. But if while it is impossible fundamentally to change the device batteries, you can try to make them at least less dependent on the outlet. This is what took up German scientists, creating technology, greatly accelerates the charging of batteries.

About the new development writes the edition Advanced Functional Materials. As stated in the article, a group of German scientists has developed a process for the synthesis of a hybrid material consisting of nanoparticles of tin oxide doped with antimony. All particles do not exceed a size of 3 mm and are grown on the platform of graphene, which provides structural stability and increases the conductivity. As stated by the study's author, Dina Fattakhova-Rohlfing from the Research Institute of energy and climate at jülich

«Doping with antimony improves the ability of a material to absorb lithium ions and makes the anode more fast. Thus he is able to save half as much energy in one minute than it can do the usual graphene anodes. As a result, over 1 hour of charging, the amount of stored energy increases 3 times».

High energy is retained even after 1000 charge cycles, saving more than 77% of the original capacity, which is a very good result.

«Composite materials of nitrogen oxide-carbon matrix can overcome the limitations of the individual material, such as a low cyclic stability due to large volume changes during charging-discharging».
