PolyJoule Debuts its Second-Generation Conductive Polymer Battery: The Energy Reservoir

PolyJoule, Inc., a conductive polymer battery technology provider, announced today its second-generation cell, the Energy Reservoir, as a leap forward in metal-free batteries to meet the storage industry’s growing demand for better safety, lower costs, longer lifetimes, and higher energy densities. The new cell platform increases PolyJoule’s cell and system level energy densities multiple times over its previous generation cells, while maintaining PolyJoule’s technical reputation for long cycle life and uncompromising safety.

PolyJoule’s CEO, Eli Paster, commented that “the Energy Reservoir is the result of listening to our customers. They wanted higher energy density, longer duration systems and more cell-to-system flexibility, without sacrificing PolyJoule’s leadership in battery sustainability and safety.” The Energy Reservoir expands PolyJoule’s product portfolio to now serve duration and power applications under the same technology umbrella. The company’s previous generation cells have been operating in industrial UPS environments at the megawatt scale for over three years and have passed rigorous safety certifications (UL9540A) to validate that PolyJoule’s conductive polymer batteries do not enter thermal runaway.

PolyJoule also provided updates on its in-house manufacturing capabilities. The Energy Reservoir is currently being produced at the company’s Billerica, MA facility through its own proprietary manufacturing process. PolyJoule utilizes legacy manufacturing value chains and does not require clean rooms and specialized equipment for production. Paster added that: “PolyJoule’s team built out the manufacturing processes while simultaneously re-inventing the cell architecture and augmenting the chemistry to make the Energy Reservoir a reality. There are patented innovations that drive down costs across the board for us, such as new electrodes that are 10 to 20 times thicker than industry standard that still deliver exceptionally high round trip efficiencies.”

On February 25, PolyJoule plans its first public showcase of the Energy Reservoir cells and modules at Intersolar & Energy Storage North America (Booth 1649) in San Diego, CA.
