BILLERICA, Mass.—PolyJoule, Inc., a provider of conductive polymer battery technology, recently introduced its second-generation cell, the Energy Reservoir. In a company release, PolyJoule called the battery “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 is reported to increase PolyJoule’s cell- and system-level energy densities by multiple times over its previous generation cells. At the same time, it is said to maintain PolyJoule’s “technical reputation for long cycle life and uncompromising safety.”
“The Energy Reservoir is the result of listening to our customers,” said PolyJoule CEO Eli Paster, in the release. “They wanted higher energy density, longer duration systems, and more cell-to-system flexibility, without sacrificing PolyJoule’s leadership in battery sustainability and safety.”
PolyJoule is a Boston-based, MIT spinoff that is pioneering conductive polymer battery technology built from non-metallic, rare-earth-free, polymer supply chains. The company develops and deploys what it describes as “ultra-safe, sustainable, long-life, low-cost battery energy storage systems.”
According to PolyJoule, the Energy Reservoir expands the company’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 more than three years, the company said, 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 facility through its own proprietary manufacturing process, the company stated in the release.
PolyJoule uses legacy manufacturing value chains and does not require clean rooms and specialized equipment for production.
“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,” Paster added. “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.”
