Solvay Specialty Polymers, a global producer of plastics, has launched a sustainability programme called LIFE+ GLEE to limit the use of harmful solvents in lithium-ion battery manufacturing processes.
The substance Solvay is targeting for elimination is N-Methyl-2-pyrrolidone (NMP) which has been classified as a substance of very high concern under the European Chemicals Agency REACH classification. This means it has carcinogenic, mutagenic, or toxic effects for reproduction properties. Current manufacturing processes use the organic solvent because cathode materials are sensitive to water.
