The company has patented the technology in South Korea and the US. According to Samsung, the new material can increase the battery capacity by 45 percent and can speed up charging time by about five times. As current lithium-ion batteries take an hour to fully charge but this new tech will reduce it to 12 minutes. Further, batteries that use graphene ball material can also maintain a temperature of 60 degrees Celsius that is what required for use in electric cars. The company also adds that in such a way the technology will have a serious impact on several devices from smartphones to electric cars. “In theory, a battery based on the “graphene ball” material requires only 12 minutes to fully charge. Additionally, the battery can maintain a highly stable 60-degree Celsius temperature, with stable battery temperatures particularly key for electric vehicles,” reads Samsung blog. If we talk about the material, Graphene is highly conductive and durable material which is an allotrope of carbon. The scientists have been looking at it for years as an alternative to silicon and other forms of carbon to use in everything from processors to batteries. The SAIT researchers have used these graphene balls as material for anode and cathode on lithium-ion batteries. 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.”
