Usually, it takes an hour to completely charge a phone with even with fast charging battery technology. Would you be amazed if I say you can charge your phone’s battery in just 12 minutes? Yes, Samsung is working on a new technology to produce next-generation batteries that can charge 5x times faster than the traditional old lithium-ion batteries.
Recently, a team of researchers at the Samsung Advanced Institute of Technology (SAIT) developed a 3D pop-corn like “graphene* ball,” using silicon oxide from a high strength and conductivity material called Graphene.
In the research, the SAIT collaborated with a team from Seoul National University’s School of Chemical and Biological Engineering and the Samsung SDI. They also filed two applications for the “graphene ball” technology patent in the US and Korea.
Graphene ball is a unique battery material that can increase the capacity of a battery by up to 45% and 5 times faster-charging speed than a traditional Li-ion battery. It was utilized for both the anode protective layer and cathode materials in lithium-ion batteries to increase the charging capacity and decrease the charging time as well as to maintain stable temperatures. An added advantage of the battery is that it can maintain a highly stable 60 degree Celsius temperature. Stable battery temperatures play a key role in electric vehicles.
Dr. Son In-hyuk, who led the project on behalf of SAIT, said, “Our research enables mass synthesis of multifunctional composite material graphene at an affordable price. At the same time, we were able to considerably enhance the capabilities of lithium-ion batteries in an environment where the markets for mobile devices and electric vehicles is growing rapidly. Our commitment is to continuously explore and develop secondary battery technology in light of these trends.”
However, the next generation battery market is particularly related to mobile devices and electric vehicles.
The results of the SAIT’s research has been published in a science journal in an article entitled, “Graphene balls for lithium rechargeable batteries with fast charging and high volumetric energy densities.”
