The wonder material graphene is an allotrope of carbon, and has been looked at for years as an alternative to silicon and other forms of carbon in everything from processors to batteries.
Samsung said in theory, graphene ball-based batteries require only 12 minutes to fully charge, which could be revolutionary for both mobile devices and electric vehicles. The company adds that compared to conventional lithium-ion batteries, graphene ball-based batteries are much more cool running and can maintain a stable temperature of 60-degrees Celsius. It points out that "stable battery temperatures [are] particularly key for electric vehicles."
In its research, SAIT(Southern Alberta institute of technology) sought for approach to apply graphene, a material with high strength and conductivity to batteries, and discovered a mechanism to mass synthesise graphene into a 3D form like popcorn using affordable silica (SiO2). This 'graphene ball' was utilised for both the anode protective layer and cathode materials in lithium-ion batteries. This ensured an increase of charging capacity, decrease of charging time as well as stable temperatures
Dr. Son In-hyuk, who led the project on behalf of SAIT, said, "Our research enables mass synthesis of multifunctional composite material graphene at an affordable price. At the same time, we were able to considerably enhance the capabilities of lithium-ion batteries in an environment where the markets for mobile devices and electric vehicles is growing rapidly. Our commitment is to continuously explore and develop secondary battery technology in light of these trends." Well, having this battery in our modern day smartphone will only be a matter of time. More updates to come in later period
