International Battery, an Oakland, N.J.-based maker of large-format, rechargeable lithium-ion cells and batteries, has raised $35 million in Series C funding. The round was led by existing shareholder Digital Power Capital, an affiliate of Wexford Capital.


International Battery (IB), a leading manufacturer of large-format, rechargeable lithium-ion cells, batteries, and systems, announced today the first closing of its $35 million Series C financing round, led by Digital Power Capital, an affiliate of Wexford Capital LP. The new investment will allow the Company to continue to scale up its existing manufacturing plant in Allentown, Pennsylvania, and will support expanded efforts and staffing in sales and engineering, as well as new product development.

International Battery’s proprietary large-format, prismatic lithium-ion technology allows it to offer customers innovative battery system solutions. The Company’s products are used in a variety of stationary (including electric utility/smart grid), transportation and military applications.
