‘Lightbulb moment’: the battery technology invented in a Brisbane garage that is going global

Dominic Spooner's startup Vaulta is working on a reusable battery casing to create less waste and a lighter product

As some of the world's largest companies invest billions to advance battery technology, Dominic Spooner has been working at solving the next problem: the impact of unwieldy - and environmentally unfriendly - battery casings.

Spooner runs his lightweight battery casing technology firm Vaulta from a shared garage in Brisbane's north. Batteries will change our lives in ways that we're maybe not even totally aware of, but ... we can create our own new group of problems if we're not careful," he says.
