Celgard and C4V will collaborate on the development of separator solutions for the lithium-ion battery market
Celgard, a subsidiary of Polypore International (Polypore) has entered into a strategic alliance agreement with lithium-ion battery technology company C4V to advance the development of next-generation, high-performance, high-voltage battery cells.
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.”
Polypore’s parent company, Asahi Kasei, may also support C4V’s cell manufacturing franchise.
BM-LMP cell production from the premier C4V cell manufacturing franchise started in August 2022. The three existing franchises are expected to further expand to a total of 10 giga-factories by 2030. BM-LMP high-voltage battery cells achieve long cycle life and rapid charging without the use of cobalt or nickel, which diminishes the risk posed by thermal runaway and uncertainties in raw material supplies of these elements.
