In most methods for manufacturing battery electrodes, the dry mixing of materials is a distinct step that often needs help to achieve uniformity, particularly on a large scale. This lack of homogeneity can result in variable battery performance.
Dry electrode processing utilizes high energy physical mixing for uniform distribution of materials without the aid of solvents. Thus, dry mixing, which combines the active materials, conductive agents, and binders in a solid state, presents challenges in terms of realizing a uniform distribution in the entire electrode.
At this stage, the predominant method employed by the majority of battery manufacturers for battery electrode production is the conventional slurry-casting (SC) process, also referred to as the wet process .
