Catenaa, Friday, November 21, 2025- Researchers at Monash University have successfully developed a new graphene-based supercapacitor that achieves energy storage capacity comparable to traditional lead-acid batteries.
This technological breakthrough, which also delivers power at significantly faster rates, opens promising prospects for applications in electric vehicles, grid storage, and consumer electronics.
The team’s innovation, called multiscale reduced graphene oxide (M-rGO), uses a highly curved graphene structure produced through rapid thermal annealing, maximizing the material’s surface area for energy storage.
This architecture allows ions to move efficiently, combining high energy density with high power density -a balance rarely achieved in a single device.
When assembled into pouch cell supercapacitors, the devices reached volumetric energy densities of 99.5 Wh/L and power densities of 69.2 kW/L.
They also demonstrated rapid charging capabilities with strong cycle stability.
The material is derived from natural graphite, making it scalable and compatible with Australian resources.
The research is led by Professor Mainak Majumder, Dr. Petar Jovanović, and Dr. Phillip Aitchison, with commercialization efforts underway via Monash spinout Ionic Industries.
The team envisions fast-charging, high-energy supercapacitors for applications where both rapid power delivery and substantial energy storage are critical.
