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 US Environmental Protection Agency (EPA) as an “unreasonable risk” to workers in certain conditions.

“PPG is eager to partner with the Cellforce Group to build the next generation of battery cell technology that will define a new level of sustainability for the electro-mobility segment,” said Markus Vogt, PPG general manager of mobility. “Additionally, the partnership enables collaboration to provide critical technology development to increase cell performance and safety.”
PPG’s dedicated team of mobility professionals provides differentiated solutions for automotive electro-mobility, such as sustainable binder solutions for the battery cell and coating solutions for the battery pack that include battery fire protection, anti-corrosion coatings for battery packs/trays, dielectric shielding and thermally conductive materials.
