Samsung Graphene Batteries – Promise 12 Minute Charging
November 29, 2017 7:20 AM
Samsung claims to be making breakthroughs in using graphene instead of lithium for batteries.
Graphene is the carbon allotrope which is used to power phones and electric vehicles. Samsung has processed the carbon allotrope into a ‘graphene ball’ which is used to make batteries. According to Samsung, a battery made with this material will be able to hold 45 percent capacity than a lithium one, recharge fully in just 12 minutes.
The researchers discovered the graphene ball material while working on method to mass synthesize graphene, for its high strength and conductivity. Fused with silica to make balls, it is utilized for both the anode protective layer and cathode materials in lithium-ion batteries, and allows for the aforementioned benefits of faster charging and increased capacity.
Currently Samsung has two patents for this technology, so hopefully we should see smartphones with graphene batteries being launched sometime in the near future.
