Microporous, a leading manufacturer of advanced battery separators and a portfolio company of Trent Capital Partners, has secured final funding for a new manufacturing facility in Danville, Virginia. Financing is being provided by Trent Capital Partners, Eagle Point Credit Management, and Elda River Capital Management, completing the capital structure needed to move from planning into construction. With comprehensive financing now in place, construction on the new plant is set to begin in May 2026. The Danville facility will produce battery separators for lithium-ion batteries across automotive, industrial, and grid applications.
At full capacity, the new facility is expected to support approximately 65 gigawatt-hours of battery production annually, representing a significant augmentation of Microporous’ existing production capacity in Piney Flats, Tennessee, and at its facility in Feistritz, Austria. The investment is described by the company’s backers as a critical step in expanding Microporous’ ability to serve rapidly growing demand for energy storage solutions, and as a meaningful contribution to re-shoring critical battery component production within the United States. The Danville facility is expected to contribute to regional economic development through job creation and long-term investment in the area.
Microporous has a history spanning more than 90 years and occupies a specialized position in the lithium-ion battery supply chain. Battery separators are a critical component in the performance and safety of lithium-ion cells, and Microporous produces separators used by customers across automotive, industrial, and energy storage sectors. The Danville facility will expand the company’s footprint at a moment when demand for domestic battery supply chain capacity is accelerating, driven by the electrification of transportation and growing investment in grid-scale energy storage.
Eagle Point, which focuses on infrastructure credit and energy-transition investments, described the partnership as placing it at the forefront of financing critical supply chain resilience in the energy ecosystem. Elda River, a real assets investment firm focused on energy and energy infrastructure with more than $7.3 billion of capital committed since inception, highlighted the significance of establishing a state-of-the-art domestic facility as a contribution to both innovation and energy security. Additional project details are expected to be shared as development progresses.
