Slurry mixing is the first step of the electrode manufacturing process, and the process is done separately for cathode and anode materials. The key measurable characteristics of this process (viscosity, density, solid content) will directly affect the quality of the battery and the uniformity of the electrode.
Mixing — Electrode slurry preparation process To produce an electrode slurry, the raw active materials are combined with solvent, binder, and additives. Slurry mixing is the first step of the electrode manufacturing process, and the process is done separately for cathode and anode materials.
The key measurable characteristics of this process (viscosity, density, solid content) will directly affect the quality of the battery and the uniformity of the electrode. In the mixing process, the formulation of raw materials, mixing steps, mixing time are all important parameters.
In addition, with large factories needing to be climate controlled for cathode processes, being able to produce such a large amount of slurry from a small space translates into large energy savings even for the building required to house the equipment.

The first stage in battery manufacturing is the fabrication of positive and negative electrodes. The main processes involved are: mixing, coating, calendering, slitting, electrode making (including die cutting and tab welding). The equipment used in this stage are: mixer, coating machine, roller press, slitting machine, electrode making machine.
The industrial production of lithium-ion batteries usually involves 50+ individual processes. These processes can be split into three stages: electrode manufacturing, cell fabrication, formation and integration. Equipment plays a critical role in determining the performance and cost of lithium-ion batteries.
