Are Graphene batteries the future? Check out our latest article to find out. 👉 energy battery
By Akanksha UradeSep 20 2022 The most common criticism of electric vehicles and smartphones is that they take too long to charge. Why would anyone want to drive a car requiring more than a minute of recharging? Imagine, however, an electric vehicle with a battery that charges extremely quickly and has a long driving range, or visualize a smartphone that sets in under a minute. Although it might seem impossible, the advancements in graphene batteries are bringing these possibilities to life.
Another problem with lithium-ion batteries is recyclability. Most of the parts in lithium-ion batteries are not biocompatible, making the recyclability process very expensive. Graphene-Aluminium Hybrid Battery In collaboration with Graphene Manufacturing Group, researchers at the University of Queensland Australia have developed a graphene-based hybrid battery prototype. This battery uses graphene and aluminum as electrode materials and is generally referred to as a graphene aluminum battery. The battery has an energy density of 150-160 Wh/kg, and it can be charged extremely fast within 1-5 minutes.
Graphene Enhanced Lithium-Sulfur Battery The watershed moment in the development of graphene hybrid batteries came at the end of 2021, when California-based company Lyten announced that they had developed a graphene battery for electric vehicles with an energy density three times the energy density of traditional lithium-ion batteries.
Graphene Enhanced Polymer Battery PolyJoule, a Massachusetts Institute of Technology spin-off company, recently announced a new battery technology for high-power data center backup and power grid applications. The device is a two-electrode electrochemical cell with a carbon-graphene hybrid and a conductive polymer. The battery can discharge up to 1 MW of power in less than 10 seconds and recharge in less than five minutes.
The Future of Graphene Batteries Tesla recently announced that their Model 3 battery has an energy density close to 260 Wh/kg. Still, it requires a complicated cooling system to prevent overheating and thus takes up a lot of space. On the other hand, because graphene batteries do not overheat or explode, there is no need for a cooling system, and the space could be used for energy-storing batteries in electric vehicles.
