If this technology by Samsung makes its way to mainstream consumer devices, it will definitely be a step forward in making smartphones smarter.
Here's a brief description of the new materials via the Mail: "Graphene is a single atomic layer of carbon atoms bound in a hexagonal network". The graphene balls were then used as anode and cathode for lithium-ion batteries. It is not easy to increase battery capacity and it still takes at least an hour to completely charge a battery.
The team of researchers behind this says that an average smartphone battery filled with these "Graphene balls" can be topped-up within 12 minutes and also enable a 45 percent boost in capacity. The firm believes that, the Graphene can provide stability up to 60 degrees Celsius. Even though we have proprietary techs like OnePlus's Dash Charge and Huawei's SuperCharge, the charging time is always above an hour, notes Digital Trends.
"In theory, a battery based on the "graphene ball" material requires only 12 minutes to fully charge", says Samsung. After 16 years of extensive usage of lithium-ion in batteries, Samsung chose to experiment with a material called graphene.
Lithium-ion batteries were first commercialized in 1991 and have since been the standard for use in electronic devices.
We know all that thanks to a slew of newly discovered Samsung patents describing new technologies that are in the works at Samsung right now. Importantly the process is said to be affordable, so economics should encourage the new battery tech to be adopted swiftly. Each graphene ball is composed of a SiOx nanoparticle center and surrounding graphene layers, constituting a 3D popcorn-like structure.
