Graphene Ball technology “would see its charging time cut from over an hour to just 12 minutes” plus an improved stable temperature range.
“Lithium-ion batteries are getting a lot of attention these days. They are used in both smartphones as well as electric vehicles and there is a constant strive to enhance their life while cutting down their charging time simultaneously.
Samsung Advanced Institute of Technology (SAIT) scientists have reported a breakthrough in graphene ball technology that might be the key to achieving that goal.
These promising features have led the scientists to incorporate graphene in the lithium-ion batteries somehow. The scientists at SAIT working together with a team from the Seoul National University’s School of Chemical and Biological Engineering have mixed graphene with silica to produce graphene balls through a process called chemical vapor deposition.
These graphene balls were used as a material for the anode were also coated onto the nickel-rich cathode as a protective layer. This protective layer not only controls the side reaction but also provides extra conductive pathways….
According to the combined team, a full lithium-ion battery incorporating the graphene ball technology would see its charging time cut from over an hour to just 12 minutes. Furthermore, it will also provide a 45% boost in capacity and maintain a highly stable temperature of 60 degrees Celsius. Stable temperature range is one of the key concerns when it comes to the batteries of electric vehicles.”
