PPG announced that it has partnered with Cellforce Group, which is a joint venture between Porsche and CUSTOMCELLS, to develop exclusive sustainable battery cell solutions to better serve the electric vehicle and mobility segment. PPG will supply cathode binder systems, which are free of N-Methylpyrrolidone (NMP) solvent, to the Cellforce Group. The collaboration would eliminate the use of NMP in producing the conductive-carbon slurry that forms cathodes for Li-ion batteries.

NMP, which is widely used in electrode manufacturing, has been identified as a reproductive hazard by several global regulatory agencies and was recently identified by the U.S. Environmental Protection Agency (EPA) as an “unreasonable risk” to workers in certain conditions.
