Graphene Has Been Trialled. Now It Has to Be Repeatable.
Why consistency, purity and application-ready delivery are becoming the real differentiators in industrial graphene
By Matt Prentice, Vice President – North America, Levidian
This year marked my seventh Battery Show, and one thing has become increasingly clear: the graphene conversation has changed.
Almost every serious manufacturer I speak with has trialled graphene in some form. The question is no longer simply whether graphene can improve a material, but increasingly what graphene was tested, how pure and consistent it was, and whether the same material can be delivered in the same usable form, repeatedly at industrial scale.
That distinction matters because graphene is not a single, interchangeable material. Purity, morphology, consistency and particle distribution all influence performance, and a promising result from one sample has limited commercial value if the next batch behaves differently.
At Levidian, we've long recognised the importance of continuously manufacturing G3 graphene with consistent characteristics at scale, but customers increasingly expect that same consistency in the way the material is delivered and incorporated into their products.
From graphene trial to direct-to-trial
One of my biggest takeaways from CAMX and The Battery Show is that manufacturers aren't looking for another graphene sample to study. They want something they can put directly into a development programme.
Historically, receiving graphene often meant beginning another development exercise: how to disperse it, what equipment to use, how long to mix it and whether the particles were properly distributed before meaningful testing could even begin. That is exactly the barrier we're trying to remove with NanoFlow™.
We can take consistently manufactured G3 and deliver it as a highly homogeneous, application-ready dispersion across systems including water, solvents and oils, depending on the application. The objective isn't simply putting graphene into a liquid, but achieving excellent particle distribution and homogeneity, and then reproducing that consistently at production scale.
That changes the conversation from how are we going to disperse this graphene? to what loading do we want to test? Measured dosing and straightforward redispersion allow customers to move much more quickly into performance testing and validation, which ultimately means faster adoption.
Enhance the material, not disrupt the process
Manufacturers aren't adopting graphene because they want graphene. They're trying to improve a product.
At The Battery Show, thermal management was front and centre, driven by higher C-rates, faster charging and increasing power density. But regardless of whether the target is thermal, electrical or mechanical performance, the same rule applies: the enhancement has to work within the customer's existing system.
An improvement in conductivity is of little commercial value if it creates unacceptable viscosity, fluidity or processing changes. Our approach is therefore to formulate around the application, maintaining those characteristics where required and changing them only when the customer wants us to.
That combination of material consistency and application expertise is increasingly where we see the market placing value.
Consistency has to extend beyond the graphene
If a manufacturer qualifies a formulation using G3, the next delivery needs to behave like the first. That requires consistency not only in the graphene itself, but in its dispersion quality, particle distribution and delivery system.
Excellent dispersions can be produced in a laboratory, but the harder challenge is reproducing that quality reliably at commercial scale.
For me, this is where NanoFlow represents something more important than a new product range. It combines consistent graphene, scalable manufacturing and repeatable, application-ready delivery, helping to turn graphene from an advanced material into an industrial ingredient.
What happens next matters most
Supply-chain security and North American production are also becoming increasingly important, particularly across batteries, energy, advanced manufacturing and defence. Levidian's LOOP technology gives us the opportunity to produce graphene closer to demand, adding another dimension to the consistency and scalability story.
Ultimately, though, the real measure of progress isn't how many conversations happen at a trade show, but what happens afterwards. Does the conversation become a trial? Can the customer generate measurable data, reproduce the result and ultimately turn it into a commercially viable product?
The graphene industry has spent years demonstrating what graphene can do. I believe the next phase will be defined by something much more practical: whether companies can deliver the right graphene, with the same characteristics, in the same usable form, repeatedly and at industrial scale.
That is increasingly what will separate graphene suppliers from the companies that actually drive graphene adoption.
