Promethean Clay

Current energy storage devices are constrained by their reliance on rigid, heavy exoskeletons that add parasitic mass and constrain energy storage improvement. These structural frameworks impose fundamental barriers to achieving generational leaps in energy storage capability. 

Promethean Clay seeks to overcome these limitations by creating a new class of energy storage devices that eliminate the rigid exoskeleton entirely, instead relying on mechanically co-designed materials that integrate structural support and energy storage functions within the device itself.

The program’s central technical challenge lies in this mechanical co-design, requiring materials that maintain continuous mechanical connectivity and uniform stress distribution across interfaces while preserving robust energy storage functionality. Through a multi-phase effort, Promethean Clay will design and demonstrate prototypes with thermal resilience and safety performance exceeding the state of the art.

If successful, Promethean Clay will establish a fundamentally new paradigm for energy system design that is unconstrained by rigid packaging or external pressure, while enabling significant performance gains and a viable pathway to domestic materials sourcing and manufacturing.
