Samsung Develops ‘Graphene Ball’ Battery Material Which Allows 12 Minutes Full Charge

Lithium-ion batteries are widely used on most mobile devices since 1991, and as we all know, a standard lithium batteries requiring charging times of at least an hour to charge fully. Samsung which has been at the forefront of mobile phone and battery development, through its research team at the Samsung Advanced Institute of Technology (SAIT) developed a ‘graphene’ ball battery material that enables up to 45% increase in capacity, and five times faster-charging speeds than standard lithium-ion batteries.

According to the team who worked with Samsung SDI and National University’s School of Chemical and Biological Engineering Seoul revealed that the graphene ball material requires only 12 minutes to fully charge a standard lithium batteries and can maintain high stability even at 60 degree Celsius temperature.

Speaking on the groundbreaking research 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.
The institution which has also filed two applications for the “graphene ball” technology patent in the US and Korea revealed that by coating the electrodes with a thin, popcorn-shaped layer known as a "graphene ball," they were able to produce a battery that could fully charge in just 12 minutes with up to 45 percent more capacity. 

The research will lead to faster-charging electric vehicles and also reduce the wear and tear on them. The company aims to achieve this by coating nickel-rich cathodes and lithium-based anode materials to improving the cyclability and fast charging capability of the cathode substantially.
