The battery back of your favorite phone has been a crucial factor since times immemorial and with the advent of technology, more emphasis is given on battery department. Brands are unveiling handsets with hefty batteries and promoting the battery backup of their devices far and wide. The latest technology to join the league is a new Supercapacitor Tech from the University of Central Florida where a supercapacitor battery prototype has been built which can last 20 times longer than the current lithium-ion cell.
Theoretically, these supercapacitor batteries could be a dream coming true for heavy users who wish their smartphone batteries to last a little longer. Supercapacitors can store charge on the surface of the material and do not require chemical reactions for power generation. The best thing about these batteries is that they can be charged very quickly, in a few seconds to be exact and can hold power for a week without needing another charge.
Unlike current batteries which start loosing power after a time period, these supercapacitor batteries can be charged up to 30,000 times and still act as new without undergoing any degradation. The UCF team experimented with some concepts with one of them being the attachment of two-dimensional material, having a thickness of a few atoms, to the supercapacitors. The electrons were allowed to pass quickly from core to the shell which resulted in obtaining a material with high energy and power density which charges faster.
UCF’s Yeonwoong “Eric” Jung, said, “We developed a simple chemical synthesis approach so we can very nicely integrate the existing materials with the two-dimensional materialsThere have been problems in the way people incorporate these two-dimensional materials into the existing systems – that’s been a bottleneck in the field. We developed a simple chemical synthesis approach so we can very nicely integrate the existing materials with the two-dimensional materials.”
The thing worth noting here is that these batteries making use of Supercapacitor Tech are flexible which simply means that they can be used in wearables too. According to Jung, this project is just a proof of demonstration and is not yet ready for commercialization. With the advancing technology, we expect similar concepts to evolve and save us from being a wall hugger.
