Finally, the roll-milling-included procedure has been adopted as one of the most remarkable concepts for designing dry battery electrodes. The shear force created by the calender gap, pressing, and rotation ratio between rolls causes the dry-mixed power to experience additional mixing and dispersion, resulting in a smooth electrode film.
In addition, other dry electrode manufacturing techniques are being developed, such as AM Batteries (a spin-off from Worcester Polytechnic Institute), which uses the electrostatic spraying concept, further diversifies the dry electrode process techniques by referencing mature methods of different industries. 13b, 13c

slot die with a backing roll only allows coating battery electrodes one side at a time. This requires two separate passes through the same coating line, whereby a second coating station is installed after the drying oven. However, a more eficient method is to coat both sides in a single pass.
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.
