Synthesis of a precursor for a cathode material in the laboratory
The synthesis conditions for cathode materials significantly influence the properties of the end product, such as the range and fast charging capability of a battery. To meet the customers’ requirements, BASF researchers develop individual strategies for the synthesis and post-treatment of the materials.
They have several approaches: Changes in the chemical composition, morphology and synthesis parameters. Cathode materials for lithium-ion batteries usually consist of mixed metal oxides. In the first synthesis step, various metal salts are precipitated with sodium hydroxide and then calcined at more than 700°C. Depending on the required property profile, the cathode materials are additionally post-treated. BASF is a strong player in the battery materials market and runs pilot and production plants in all major regions.
