Celgard Announces Strategic Alliance Agreement with C4V for High-Voltage Lithium-ion Batteries for Giga-factories

Celgard and C4V will collaborate on the development of separator solutions for the lithium-ion battery market optimized for C4V's high-voltage bio-mineralized lithium mixed metal phosphate (BM-LMP) cathode material.

This collaboration is part of C4V's Supply Chain Partner program, whereby key needs of the battery industry are targeted, and solutions are brought to market.

Celgard® membrane separators developed under the alliance are expected to gain access to all C4V's member giga-factories. Celgard's innovative separator could supply a cell manufacturing base with over 150 GWh of cell production planned for 2030.

These cell production sites are located in the USA, India and Australia, with additional facilities under development elsewhere. Celgard is already a certified member of C4V's Supply Chain Partners program with a current generation of Celgard® separator.   

Stefan Reinartz, Celgard's vice president of lithium-ion electric drive vehicle (EDV) and energy storage systems (ESS) business, said: "We are pleased to partner with the technology leader C4V to advance Celgard® dry-process battery separators and develop innovative solutions for BM-LMP battery cells with them. C4V has proven they can bring high-precision battery manufacturing online quickly. Our alliance will pave a path to innovations that will bring affordable, high-energy output cells to people who need them urgently."
