The influences of different technologies on electrode microstructure of lithium-ion batteries should be established. According to the existing research results, mixing, coating, drying, calendering and other processes will affect the electrode microstructure, and further influence the electrochemical performance of lithium ion batteries.
The electrode and cell manufacturing processes directly determine the comprehensive performance of lithium-ion batteries, with the specific manufacturing processes illustrated in Fig. 3. Fig. 3.
Another approach for adjusting the porosity of battery electrodes, which is often discussed in the literature, is the creation of geometric diffusion channels in the coating to facilitate the transport of lithium-ions into the regions near the collector during charging and discharging.
Chemical reactions can cause the expansion and contraction of electrode particles and further trigger fatigue and damage of electrode materials, thus shortening the battery life. In addition, the electrode microstructure affects the safety performance of the battery.
The movement of lithium-ions in and out of the electrode is strongly dependent on the mass transport kinetics between the porous electrodes. Higher porosity results in larger and more microchannels, allowing the ions to easily penetrate the electrolyte-infiltrated coating of the electrode.
It is one of the hot research topics to use the systematic simulation model of lithium-ion battery manufacturing process to guide industrial practice, reduce the cost of the current experiment exhaustive trial and error, and then optimize the electrode structure and process design of batteries in different systems.
