Graphene origin
GMG's self-developed graphene process establishes the material source before slurry processing.
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
GMG positions 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
GMG links the material to charge and discharge rate-tolerance behaviour.
Product role
What SUPA G® does
SUPA G® turns GMG’s graphene capability into a material format battery teams can evaluate. Instead of presenting graphene as an abstract ingredient, the slurry gives partners a route for electrode trials and controlled integration work.
GMG says the graphene comes from its self-developed production system, is processed through a co-located pilot plant and is finally made into a liquid graphene product for lithium-ion battery electrode use.
Developed from GMG’s 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
Material format for partner testing
The product story is clearest when partners can see what is being supplied, how it enters battery-material work and which performance signals need validation.
How it fits
From GMG graphene to customer electrodes
The material path stays focused on integration: graphene source, slurry processing, low-dosage electrode use and partner validation.
Liquid graphene product
The slurry format supports practical handling, controlled application and downstream battery-material testing.
Electrode integration
SUPA G® can be added into or coated onto lithium-ion battery cathodes or anodes.
Technical proof
Reported signals from the SUPA G® material study
The technical case is strongest when the reported data is grouped around the questions battery teams ask first: resistivity, loading, surface area, density, particle structure and rate behaviour.
Ionic resistivity
2.5x
Lower mean ionic resistivity
GMG reports 2.5 times lower mean ionic resistivity than standard graphite in the recent study.
Electrode loading
0.5-2%
Typical loading by weight
Product materials describe 0.5-2 wt% loading, compared with 2-5 wt% for common carbon additives.
Surface area
250
m²/g reported surface area
GMG lists 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® is presented with 0.3-0.4 g/cm³ bulk density.
Particle structure
20 µm
Multimodal distribution
GMG describes large particles around 20 µm plus sub-1 µm particles.
Rate tolerance
High-rate
Charge and discharge relevance
GMG says its graphene increased lithium-ion battery rate tolerance.
Study figures
Figures and comparison table for SUPA G®
GMG presents three technical figures and a comparison table. Keeping them together makes the evidence easier to scan before the contact step.

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. It supports battery work, but it is not a finished battery cell.
Where can it be used in lithium-ion batteries?
GMG describes SUPA G® as 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?
Partners can discuss the target application, material requirements, validation method and commercial assumptions with GMG.
