The Samsung Advanced Institute of Technology (SAIT) has developed new battery material, made from a “graphene ball,” which could potentially deliver charging speeds five times faster than today’s lithium ion batteries. Samsung announced the new material in a press release this past Wednesday, November 28.
But just how fast is this new material? Well, in theory, this graphene ball material only needs about 12 minutes to achieve a hundred percent charge. But it shouldn’t come as a surprise that this breakthrough material comes from graphene. The 2D-material has long been regarded as a wonder material because of its combination of unique properties. Graphene, among other things, is strong, durable, and highly conductive.
SAIT researchers, led by Son In-hyuk, developed a mechanism that allows for graphene to be mass synthesized into a 3D popcorn-like form using silica (SiO2). The graphene ball, in this technique, is applied to both the anode protective layers and the cathode materials in lithium-ion batteries.
Aside from faster charging, batteries built from this graphene ball can maintain highly stable temperatures at 60-degrees Celsius, according to the SAIT researchers who published the details of their work in the journal Nature Communications. Such stable battery temperatures are crucial for EVs, Samsung explained.
“Our research enables mass synthesis of multifunctional composite material graphene at an affordable price,” In-hyuk, explained in the press release. “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.”
