Researchers at the South Korean Samsung Advanced Institute of Technology (SAIT) have developed batteries that charge faster and last longer.
According to research published in the journal Nature Communications, SAIT researchers in collaboration with a team from Seoul National University have developed a “graphene ball” capable of providing a 45 percent increase in battery capacity, while also being able to charge five times faster than regular lithium-ion batteries.
The graphene ball itself is made of a combination of silicon oxide, graphene, as well as nickel. The ball was developed when the team discovered a way to mass-produce graphene “into a 3D form like popcorn.”
“Our research enables mass synthesis of multifunctional composite material graphene at an affordable price,” said Dr. Son In-hyuk, the lead researcher from SAIT. “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 if growing rapidly. Our commitment is to continuously explore and develop secondary battery technology in light of these trends.”
Samsung suggests that a battery based on the ‘graphene ball’ material should theoretically require only 12 minutes to fully charge,” reads an excerpt from a November 28th, 2017 Samsung media release.
The graphene ball technology can also maintain a consistent temperature of 60 degrees Celsius, which Samsung posits could make the technology beneficial for electric vehicles.
