More and more claims about breakthroughs in the field of battery technology seem to have been coming in recently. On closer inspection, however, many of these claims actually only relate to minor steps in the long journey toward any possible market launch. But one new report of major progress looks much more promising. The Samsung Advanced Institute of Technology (SAIT), the Korean conglomerate’s research department, has announced that it has successfully synthesized a "graphene ball" set to significantly increase both capacity and charging speeds for lithium-ion batteries. The Samsung researchers have calculated a 45% increase in capacity and a five-fold boost to charging speeds.
As a result, the charging time for a lithium-ion battery could be cut from an hour to just 12 minutes. What's more, the new graphene ball batteries are designed for operating temperatures of up to 60 degrees Celsius, making them ideal for charging electric vehicles in record time. This could prove to be a huge boost to electromobility. These high hopes are all thanks to the use of graphene, a material that has already gained an almost legendary reputation in battery engineering and beyond. Based on carbon, graphene has proved to be exceptionally conductive and robust. According to results published in the scientific journal Nature, the SAIT researchers have succeeded in using silica (SiO2) to synthesize three-dimensional graphene into a form that resembles popcorn when viewed under a microscope. Used as anodes and cathodes in lithium-ion batteries, these "graphene balls" truly do seem to be getting a real breakthrough rolling.
