Designing the battery that changes
transportation and energy as we know it

We envision a future in which our homes and offices are powered by renewable energy and our cities have more emissions-free e-bikes and scooters than cars. But we’re not going to get there without breakthroughs in battery technology that can be produced in today’s factories.

Many of today’s new battery technologies are promising but remain years away from mass production. We don’t have the time to retool factories for battery types that may be too expensive or not recyclable.

By integrating a solar-inspired technology into stack-and-seal lead battery forms, Gridtential has cracked the code on energy storage.

Our Silicon Joule technology enables the mass production – in today’s factories – of high-voltage, safe, recyclable batteries for personal mobility vehicles, home or office energy storage systems, hybrid cars and industrial backup systems.

Together with our partners – the world’s leading battery manufacturers – we are working to bring our vision of an emissions-free world to life, today.
