Anode and Cathode Materials

One option for the synthesis of cathode and anode materials is the so-called solid-state process. In this process route, the active material is created from the raw materials through a chemical transformation in suitable furnaces. Depending on the raw materials used, a wet grinding stage with dry pre-grinding processes can be required for the raw materials prior to the synthesis.

The CGS and s-Jet^® fluidized bed jet mills can be used for the dry grinding. For the wet grinding, the Zeta^®, Neos or Zeta^®RS agitator bead mills are used, depending on the required target fineness. Synthesis via a furnace process can result in the formation of undesired agglomerates. In order to separate these, a dry dispersion with a CSM classifier mill is usually carried out after the synthesis furnace, without change of the original size and shape of primary particles.
