Graphene is a material that is now a part of many exciting future projects from purifying sea water to detecting cancer. Scientists have no created a “graphene-ball” coating inside a regular lithium-ion batteries which has the effect of increasing the overall capacity upto 45 percent and spending up charging by five times.
Up till now, we have seen Qualcomm’s fast charging capabilities, OnePlus’s Dash Charging and even Huawei’s SuperCharge, but the overall charging time never dips below an hour. Samsung Advanced Institute of Technology has pushed themselves really high to make this possible.
If you phone charges up in 90 minutes now, that number will tumble to just 18 minutes if the cell inside has been given a graphene ball boost. What’s more, this doesn’t seem to affect the cell’s lifespan, with the team claiming that after 500 cycles, the enhanced battery still had a 78 percent charge retention. The graphene coating improves the stability and conductivity of the battery’s cathode and electrode, so it’s able to take the rigors of fast charging with fewer downsides.
Samsung’s research team have published a very technical paper about how the graphene ball worls and how to produce them. The technology is currently in its alpha stage and is unlikely to be seen in Samsung’s next flagships but will definitely have an impact on future battery technologies. Who wouldn’t like to have a fast charging plus long lasting battery on their phone?
Li-ion batteries power not only our mobile gadgets, where fast charging is a extremely helpful, but they are also used in electric vehicles, where fast charging is essential for wider adoption. Samsung says it’s possible the graphene ball technology can be scaled up from small capacity cells in our phones, to much larger batteries inside cars. The company has filed patents in the United States and South Korea for graphene ball technology, but there is no indication when or if it will reach a consumer product.
