Energy Storage, Anywhere

We're a Boston-based energy storage company pioneering conductive polymer battery technology. We have re-invented what a 21st century grid battery should be: Ultra-Safe, Sustainable, Long-Life, and Low-Cost.


Providing power and energy for the grid today and tomorrow, PolyJoule's conductive polymer energy storage provides a cost-effective, safer path to 21st century electrification: at urban load centers, remote outposts, and anywhere in-between.

Our Core Values

Ultra-Safe

Safety is paramount; Energy storage must evolve from risk mitigation to risk free

Sustainable

Everyone in the world deserves access to clean, renewable electricity; Sustainable energy storage makes that a reality

Long-Life

Reliable and efficient storage comes from intelligent and superior battery chemistry

Low-Cost

Energy storage needs to be affordable both today and tomorrow
