Australian researchers have identified “a new kind of carbon-based material” allowing supercapacitors to store as much energy as lead-acid batteries while also performing better than conventional batteries at delivering power quickly.
According to a statement from the university on Tuesday, the results are “a major leap forward” for fast, powerful energy storage devices, and are now being commercialised by Ionic Industries.
The new material is named as multiscale reduced graphene oxide (M-rGO) and was created from naturally-occurring graphite. It is described as being made using a “rapid thermal annealing process” and featuring a “highly curved graphene structure with precise pathways for ions to move quickly and efficiently”.
The promising new material is detailed in a new paper in Nature Communications.
Monash’s Professor Mainak Majumder, who was part of the research team and heads the ARC Research Hub for Advanced Manufacturing with 2D Materials (AM2D), said that M-rGO made much more surface area available for storing energy, and which was unlocked by the method of heat treatment.
