Large-scale recycling of lithium-ion cathode materials moved a step closer to market readiness when two North American firms agreed on a testing program.
US metals firm American Manganese aims to commercialise its proprietary hydrometallurgical process for the recycling of cathode materials of multiple chemistries.
Chemicals company Johnson Matthey is to license five patents as it looks to accelerate the adoption of nickel-manganese-cobalt (NMC) cathode materials in lithium-ion batteries.
The deal with US firm 3M will allow the UK firm to focus on providing a bigger portfolio of cathode materials for the automotive and high performance markets.
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.
