Project 4-3

This project aims at an evaluation of different methods for the re-synthesis of cathode materials. At laboratory scale, several synthesis methods will be established and utilized for the synthesis of NMC active materials. Subsequently, the influence of typical impurities remaining from recycling processes on the synthesis mechanisms and the composition and structure of the obtained products will be evaluated.

Specific objectives:

• Establishment and investigation of different synthesis routes for cathode materials
• Determination of the influence of impurities on the synthesis process and the properties of the synthesized material
• Adjustment of the synthesis parameters to minimize possible harmful effects of impurities
• Evaluation of additional process steps and scale-up of the synthesis

Expected outcome:

• Optimized re-synthesis of NMC materials from recycled hydrometallurgical compounds to maximize cathode performance
• Understanding the sensitivity of different synthesis processes on impurities, and the interconnection between impurities and material properties
