Scientists have developed a new graphene-based battery material with charging speed five times faster than today's lithium-ion batteries.
The breakthrough by researchers at the Samsung Advanced Institute of Technology (SAIT) in South Korea provides promise for the next generation mobile batteries and electric vehicles.
Standard lithium batteries require charging time of at least an hour to fully charge, even with quick charging technology, so numerous attempts to explore new innovative materials have been started.
Among the materials looked at, graphene, a material with high strength and conductivity, has widely become the primary source of interest.
In theory, a battery based on the "graphene ball" material requires only 12 minutes to fully charge, researchers said.
This "graphene ball" was utilised for both the anode protective layer and cathode materials.
This ensured an increase of charging capacity, decrease of charging time as well as stable temperatures.
Researchers used graphene and mass synthesised it into a 3D form using silica (SiO2).
Their research enables mass synthesis of graphene at an affordable price as the markets for mobile devices and electric vehicles is growing rapidly.
Graphene: Know More
- Graphene is an allotrope (form) of carbon consisting of a single layer of carbon atoms arranged in an hexagonal lattice.
- It is the basic structural element of many other allotropes of carbon, such as graphite, charcoal, carbon nanotubes and fullerenes.
- Graphene has many unusual properties.
- It is the strongest material ever tested,efficiently conducts heat and electricity and is nearly transparent.
- Graphene shows a large and nonlinear diamagnetism, which is greater than that of graphite, and can be levitated by neodymium magnets.
