BATTERY CONCEPT

Graphene Aluminium-Ion Battery

We’re advancing Graphene Aluminium-Ion Battery – a world-exclusive technology – in collaboration with The University of Queensland, UniQuest, Rio Tinto and the Battery Innovation Center in Indiana, USA.

6-minute charging updatesNo lithium or rare earth materialsUQ and Rio Tinto collaboration

Faster charging

Laboratory testing demonstrates six-minute full charging.

Rechargeable

Rechargeable and designed to be interchangeable with lithium-ion battery applications.

Greener and safer

The aluminium-ion chemistry uses no lithium or rare earth materials.

Strong partnerships

Developed in collaboration with UQ, UniQuest, Rio Tinto and the Battery Innovation Center in Indiana, USA

Pioneering technology

A significant step closer to reality

Laboratory testing has demonstrated high energy density and higher power-density potential compared with lithium-ion technology. We report longer battery life and much faster charging as the headline advantages, with scale-up research ongoing.

Compares with lithium-ion batteries while using a different chemistry.

Interchangeable and rechargeable, with comparable use cases to lithium-ion batteries.

No lithium or rare earth materials, for a cleaner supply chain.

Battery concept

From lab to reality

We’re building this battery step by step – testing, learning, improving. Follow our progress through lab results, official updates and real prototype trials with our partners.

Reported advantages

Battery performance at a glance

Fast charge

Faster charging

Laboratory testing has demonstrated up to 70 times faster charging compared to lithium-ion, with six-minute full charging achieved.

Life

More battery life

Early testing indicates up to 3 times longer battery life compared to lithium-ion.

Chemistry

Greener and safer

The aluminium-ion chemistry uses no lithium or rare earth materials, reducing supply-chain risk.

Energy density

49 Wh/kg progress milestone

In April 2026, GMG reported pouch-cell energy density of 49 Wh/kg – double the previous result – confirmed through BIC testing.

Readiness

BTRL 4 development stage

Battery Technology Readiness Level 4, with pouch-cell optimisation ongoing.

IP

Ongoing IP collaboration

Developed under an IP collaboration agreement with The University of Queensland.
