Since its commercial introduction in 1991, lithium-ion batteries have powered most of our mobile devices. Arguably, the advancement of technology is increasing demand for faster and denser batteries. Emerging features on smartphones, such as 4K displays, demand more battery power than ever before.
The Samsung Advanced Institute of Technology (SAIT), has developed a 'graphene ball' battery material that allows for a 45% increase in power density and 5 times faster charges compared to traditional lithium-ion batteries. This new material has the ability to maintain a stable 60 degree Celsius temperature while charging. How is would this new material be used? It is used for the anode protective layer and cathode materials while keeping lithium-ion components in current batteries.
As a comparison, an iPhone 8 with its original 12W charger and lithium-ion battery takes two hours to charge; the same phone with a graphene ball battery could be fully charged in as little as 24 minutes.
Editor’s Opinion
If implemented correctly, this material is a big step forward in battery technology. Graphene ball material means that existing battery technology can be modified easily and relatively cheaply.
