Trust NETZSCH Solutions for Battery Materials Engineers face challenges when designing lithium ion batteries. A proper thermal management strategy is required to ensure performance and the life span of the battery. The main concern with the thermal behavior of room temperature batteries is the possible significant temperature increase that may cause thermal runaway. Battery design parameters, manufacturing process and operating conditions have an effect on temperature rise/profile during battery operation. Manufacturers of battery components must deliver consistent overall quality –...

ANODE & 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...

Wet operated agitator bead mills are the most suitable technology to grind abrasive ceramic materials down to the required submicron particle size range. Different grinding systems are used depending on the required material hardness and the associated required energy density and particle size. To guarantee a total avoidance of metal contamination all machine parts with contact to the material can be made from ceramic. In order to prevent an internal short-circuit in the cells, a separator is inserted between the electrodes. The separators, which are typically made of polymer (e.g. PE, PP),...

CONDUCTIVE ADDITIVES & BATTERY SLURRIES For the production of high quality battery materials and components like active materials, additives, cathode or anode slurries and ceramic suspensions for inorganic composite separators a lot of different process steps and equipment are required. Conductive Additives The majority of active materials are in the electrode with limited electrical conductivity additionally the polymer matrix in the electrode needs to be electrical conductive. That is why additives are used also to reduce the required charging time of the battery when beeing added to the...

Battery Slurries PMH / PML planetary mixers have established themselves as state of the art for the production of so-called battery slurries. With PMH / PML planetary mixers a combination of different processes like dissolution of binders, the premixing and the alloying of the dry components, the mixing, kneading and homogenization as well as the degassing of the high viscose pasty slurries can be realized with an excellent temperature control. However, depending on the material system used, the binder can also be dissolved first and very gently mixed after addition of the active materials....
