A new battery material made from graphene can supposedly be charged fully at a rate that's five times faster than today's batteries. The development comes from Samsung's research unit dedicated to building advanced technologies.
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.
