A big breakthrough in the field of automobiles! Researchers from Korea Institute of Science and Technology have developed a new battery made from carbon-silicon material. This innovation can increase the battery capacity four-fold in comparison to graphite anode materials. Not only that, it will also improve power charging to more than 80% capacity in only five minutes.
Double the driving range of electric vehicles:
Traditional batteries used nowadays in electric vehicles use graphite anode materials. These batteries provide shorter range to EVs in comparison to the vehicles with internal combustion engines.
However these new batteries could more than double the driving range of electric vehicles. But there is one issue with Silicon anodes as well. When silicon anodes are used in batteries, its volume expands rapidly. So these are not good at holding their capacity over time.
To enhance the stability of silicon, the team, led by Hun-Gi used “a simple thermal process used for frying food,” Their experiment was successful and the resultant battery has four times the capacity of the traditional batteries. Not only that, these new batteries also remained stable over 500 cycles.
Dr. Jung, said, “We were able to develop carbon-silicon composite materials using common, everyday materials and simple mixing and thermal processes with no reactors,”
“The simple processes we adopted and the composites with excellent properties that we developed are highly likely to be commercialized and mass-produced. The composites could be applied to lithium-ion batteries for electric vehicles and energy storage systems (ESSs).”
