Nevertheless, the idea of being able to pull up, plug in, and take off again in less than a minute is a tantalizing one. For electric vehicles specifically, the list of benefits includes a long lifecycle and the ability to function efficiently over a wide range of temperatures. If you caught that thing about discharging quickly, though, that’s a problem. Deployment in electric vehicles is currently limited to secondary tasks where a quick burst of power is useful, such as acceleration and regenerative braking. In those use cases, supercapacitors avoid wear and tear on the main battery.
The researchers already anticipate that their new battery will find a use in the electric vehicle field. That may be a long ways off, but the project is off to a promising start. The team’s study was published in March by the journalThe shorter version is that the team developed a new battery that combines a new, sophisticated anode with a new cathode that accommodates supercapacitor technology.
Graphene and MXenes are 2D, atomic-level materials. Graphene is composed of a single layer of carbon atoms, while Mxenes consist of two layers of material made of metal carbides, nitrides, or carbonitrides.
