One of the most important parameters of a smart device is the capacity of the battery to ensure adequate activity during use of the device, especially when opening many applications and menus that do require considerable power. Not infrequently, global smartphone vendors are arming their flagship smartphone with jumbo power capacity and battery charging features super fast.
This indicates that the development of battery technology in the smartphone is constantly increasing. A new innovation from Samsung even allows the battery to fully charge in just 12 minutes!
The Samsung research team has developed a new type of battery material that they call 'graphene ball'. They said the technology could allow a 45% increase in battery capacity, and the speed of battery charging five times faster. This material was developed by researchers at
Samsung Advanced Institute of Technology (SAIT), in collaboration with Samsung SDI and Seoul Institute of Chemical and Biological Chemistry.
Graphene Ball is a unique material developed from Alotrope Carbon, and has been used for many years as an alternative material of silicon and a derivative of other carbon materials used in all things. Starting from the production of processor chips to battery components. This invention by Samsung seems to make the potential of this material can be utilized more optimally.
Graphene Ball battery materials can be used in the market of next generation secondary batteries, mobile devices and electric vehicles.
Samsung said that in theory, graphene ball-based batteries only require 12 minutes to fully charge the battery - which could be a revolutionary technology for mobile devices and electric vehicles.
Samsung added that if we compare with conventional Lithium-ion batteries, Graphene Ball-based batteries are much more innovative, efficient and can maintain a stable temperature of up to 60 degrees Celsius. This shows that a stable battery temperature factor is essential for electric vehicles and mobile devices such as smartphones. So in other words, can minimize the risk of overheating (overheat).
The South Korean-based electronics company added in a press release that in its research, SAIT is looking for an approach to applying graphene ball, a material with high levels of power and high electrical conductivity to batteries. So we can find a mechanism to graphene ball synthesis in bulk to 3D form like popcorn using silica. Graphene ball here is used for the anode protective layer and cathode material in lithium-ion batteries. This ensures increased charging capacity, accelerated charging time and a much more stable temperature.
Dr. Son In-hyuk, who leads the project on behalf of SAIT, said that the research they developed enabled the presence of battery charging technology with high quality and affordable price.
SAIT has published the results of its research in the journal Nature Communications, in an article entitled: "Graphene Ball for Lithium-ion rechargeable batteries with fast charging and high volumetric energy density". SAIT also said that they have filed two Graphene Ball patent applications in the US and South Korea. EKi
