Dominic Spooner is the director of the Australian startup Vaulta, which focuses on graphene-enhanced battery casings. In a recently released interview, he answers questions concerning the casings and their relationship to graphene. Below are a few of the questions asked.
Q. Can you give us a short introduction to Vaulta’s technology and business?
A. Vaulta is a battery casing technology company based in Brisbane, Australia. Using advanced composite materials and smart, streamlined design, Vaulta has developed a lighter and smaller battery case with fewer parts, creating scalable efficiencies and opportunities for manufacturers.
Vaulta’s world-first no-weld design means modules can be easily assembled and disassembled, cells reused and recycled, and new cells added as battery technology continues to evolve.
From stationary storage and electric vehicles to defense, aerospace, and beyond, Vaulta’s battery case technology works wherever batteries do.
Q. We understand that Vaulta adopts graphene in its casing to improve performance. Can you tell us in more detail how the graphene enhances the battery casing?
A. Heat is everything with batteries, and generally the most sensitive areas of a battery are the terminals. Using metals for current collection at the terminals and then plastics to house the batteries is the traditional method most often used to build a battery. By using graphene and other elements, we’ve separated thermal conductivity and electrical conductivity into two separate custom materials to allow a streamlined design that also works to remove heat from the cells directly at the terminals.
Q. Can you tell us anything regarding the graphene material adopted by Vaulta and how is it being processed?
A. A lot of the work we’re doing with graphene will be ongoing, but what we can reveal is that the results are very promising and that graphene is very much usable for commercial real-world applications. It’s no longer the unicorn concept it once was.
Overall, Dominic is positive for the future of Vaulta and graphene-based battery casings, claiming that graphene will likely be the future for battery performance and next-gen technologies.
