Microporous, a global manufacturer of advanced battery separators and a portfolio company of Trent Capital Partners, has secured final financing for a new manufacturing facility in Danville, Virginia, with construction set to begin in May 2026.
Financing is being provided by Trent Capital Partners, Eagle Point Credit Management, and Elda River Capital Management.
At full capacity, the Danville facility is expected to support approximately 65 gigawatt-hours (GWh) of battery production annually, serving demand across automotive, industrial, and grid storage applications.
The investment significantly expands the company’s existing manufacturing footprint, which includes facilities in Piney Flats, Tennessee and Feistritz, Austria, and positions the company to meet rapidly growing demand for lithium-ion battery separators.
Battery separators are a critical component of lithium-ion cells, sitting between the positive and negative electrodes to prevent short circuits while allowing the flow of ions necessary for energy storage and discharge.
As demand for electric vehicles, grid-scale storage, and industrial battery applications continues to grow, domestic production of separator materials has become an increasingly important part of the U.S. battery supply chain.
“We are thrilled to support the next phase of Microporous’ growth and for its continued expansion of lithium-ion separator production here in the U.S,” said Ray Desrocher, Managing Partner of Trent Capital Partners, in a statement. “A significant augmentation of the company’s existing lithium-ion separator production capacity in Piney Flats, TN will position Microporous to serve this exploding market for years to come.
