As one of the highly promising electrode manufacturing technologies, the dry process technology is expected to replace the wet process currently used on a large scale in state-of-the-art commercial lithium-ion batteries. However, a number of challenges remain before this new technology can be commercialized. 4.1. Study of Dry Mixing Systems

In the process chain of lithium-ion battery electrode manufacturing, the coating porosity, and with that the energy content per volume is most decisively determined by the compaction step. In research, mainly uniaxial hydraulic presses are used, whereas roll presses or calenders of technical scale are rarely utilized.
3.1.1. Higher Compaction Density Increasing the compaction density of the electrodes increases the volumetric energy density of a lithium-ion battery because a high compaction density lithium-ion battery means it can be loaded with more active material for the same volume.
Our review paper comprehensively examines the dry battery electrode technology used in LIBs, which implies the use of no solvents to produce dry electrodes or coatings. In contrast, the conventional wet electrode technique includes processes for solvent recovery/drying and the mixing of solvents like N-methyl pyrrolidine (NMP).
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.
