Battery modeling has become increasingly important with the intensive development of Li-ion batteries (LIBs). The porous electrode model, relating battery performances to the internal physical and (electro)chemical processes, is one of the most adopted models in scientific research and engineering fields.
3 · Electrodes are vital for lithium-ion battery performance. The primary method for large-scale electrode production involves wet slurry casting methods, which encounter challenges related to solvent usage, energy consumption, and mechanical stability. Dry processed (DP) electrodes are a promising alternative but struggle with rate capability …

Current battery technologies are mostly based on the use of a transition metal oxide cathode (e.g., LiCoO 2, LiFePO 4, or LiNiMnCoO 2) and a graphite anode, both of which depend on intercalation/insertion of lithium ions for operation. While the cathode material currently limits the battery capacity and overall energy density, there is a great ...
Dry battery electrode (DBE) is an emerging concept and technology in the battery industry that innovates electrode fabrication as a "powder to film" route. The DBE technique can significantly simplify the manufacturing process, reconstruct the electrode microstructures, and increase the material compatibilities. ... Solvent-free extrusion ...
Rechargeable lithium-ion batteries (LIBs) are widely used to provide energy and power in portable electronics, electric vehicles, and hybrid electric vehicles. 1–4 The LIB market has grown dramatically over the last decade because of LIBs'' high energy density, high power density, proven reliability, long cycle life, and design flexibility. 5,6 These …
In the design of a normal lithium-ion cell the electrodes are composed of active materials on current collectors which are flat sheets of copper for the anode and aluminium for the cathode. These metal sheets are around 4-9 µm thick for copper and 15-25 µm thick for aluminium and have the active materials coated on one or both sides.

Fig. 4 (a) explains how battery cells with hard casing, i.e., cylindrical or prismatic cells, are resistance spot welded with parallel weld electrodes. Apart from the desired current I weld, a stray current I stray flows. Therefore, the power source has to provide a higher current I electrode and electrode sticking may occur. In Fig. 4 (b), spot …
