Fully charge a battery in just 12 minutes; only with Samsung’s balls
Samsung’s research has yielded balls that offers faster charging and higher capacities. The “graphene balls” synthesized by Samsung Advanced Institute of Technology (SAIT) will be used for the anode and cathode in lithium-ion batteries.
The graphene balls are a graphene-silica assembly with SiOx nanoparticles coated by graphene layers. The graphene balls then coat nickel-rich layered cathodes.
The graphene balls can also serve as an anode material to support fast charging operations. Fast charging with standard graphite anodes result in the deposition of lithium metals on the surface. That doesn’t happen with graphene balls, allowing for safe and fast charging with excellent charge retention.
The result is durable batteries that can withstand a wide range of operational temperatures, have high energy density of up to 800 Wh/L and are capable of retaining 78.6% capacity after 500 charge cycles.
This method of coating the electrodes in batteries to yield batteries with more desirable characteristics has been applied by Huawei too. However the research paper points towards this graphene balls technology being used in electric cars. Nevermind, we will see it in smartphones some day. It’s Samsung, after all.
