Graphene origin
Our graphene comes from our self-developed production system and is processed through our co-located pilot plant.
Graphene materials / Battery additives
Graphene slurry for lithium-ion battery enhancement
SUPA G® is GMG’s graphene slurry for lithium-ion battery enhancement. It is designed as a liquid graphene material that can be added into or coated onto customer lithium-ion battery cathodes and anodes.

Slurry format
A liquid graphene material creates a practical route for battery trials and electrode development.
Electrode additive
We designed SUPA G® for addition into or coating onto lithium-ion cathodes and anodes.
Low loading
Product materials describe 0.5-2 wt% loading by weight for evaluation.
Rate relevance
We link SUPA G® to charge and discharge rate-tolerance behaviour.
Product role
What SUPA G® does
SUPA G® turns our graphene into a material format battery teams can test directly. Instead of an abstract ingredient, our slurry gives partners a practical way to run electrode trials and controlled integration work.
Our graphene comes from our self-developed production system, is processed through our co-located pilot plant, and finished into a liquid graphene product for lithium-ion battery electrodes.
Developed from our in-house graphene production and pilot-plant processing.
Positioned for lithium-ion battery cathode and anode development.
Built for technical validation before broad commercial claims.
Graphene slurry
A material format partners can actually test
We keep it simple: what you’re getting, how it fits into your process, and what to test first.
How it fits
From our graphene to customer electrodes
Everything stays focused on integration: graphene source, slurry processing, low-dosage electrode use and partner validation.
Slurry format
The liquid graphene format gives partners a practical way to handle, test and integrate the material.
Electrode integration
We position SUPA G® for adding into or coating onto lithium-ion battery cathodes and anodes at low loading.
Partner validation
The next step is controlled partner testing: conductivity, loading, calendaring integrity and high-rate battery behaviour.
Technical proof
What the SUPA G® material study shows
The numbers that matter most: resistivity, loading, surface area, density, particle structure and rate behaviour.
Ionic resistivity
2.5x
Lower mean ionic resistivity
We report 2.5 times lower mean ionic resistivity than standard graphite in the recent study.
Electrode loading
0.5-2%
Typical loading by weight
Our material has 0.5-2 wt% loading, compared with 2-5 wt% for common carbon additives.
Surface area
250
m²/g reported surface area
We measure approximately 250 m²/g surface area, compared with about 60 m²/g for a common additive.
Bulk density
0.3-0.4
g/cm³ reported density
SUPA G® has a bulk density of 0.3-0.4 g/cm³.
Particle structure
20 µm
Multimodal distribution
Our particles range from around 20 µm down to sub-1 µm.
Rate tolerance
High-rate
Charge and discharge relevance
In our testing, our graphene improved lithium-ion battery rate tolerance.

Partner questions
Questions a materials partner will ask first
Is SUPA G® a finished battery product?
No. SUPA G® is a graphene slurry material for battery enhancement and application development – a component for battery work, not a finished battery cell.
Where can it be used in lithium-ion batteries?
SUPA G® is a liquid graphene product that can be added into or coated onto lithium-ion battery cathodes or anodes.
Which data points matter first?
The first proof points are ionic resistivity, particle distribution, bulk density, surface area, loading range, calendaring integrity and high-rate behaviour.
What does a partner do next?
You can discuss the target application, material requirements, validation method and commercial assumptions with our team.
