The conventional way of making lithium-ion battery (LIB) electrodes relies on the slurry-based manufacturing process, for which the binder is dissolved in a solvent and mixed with the conductive agent and active material particles to form the final slurry composition.
A common material used for the positive electrode in Li-ion batteries is lithium metal oxide, such as LiCoO 2, LiMn 2 O 4 [41, 42], or LiFePO 4 , LiNi 0.08 Co 0.15 Al 0.05 O 2 . When charging a Li-ion battery, lithium ions are taken out of the positive electrode and travel through the electrolyte to the negative electrode.
These ions then traverse through the electrolyte and join with the carbon-based substance on the negative electrode, resulting in the formation of lithium compounds. Conversely, during the discharge process of lithium-ion batteries, the lithium ions move in the opposite direction, returning to the positive electrode.
The design of perfect protecting layers on Li metal anode is also a crucial subject for Li metal batteries (Liu et al., 2019a; Liu et al., 2019b; Yan, Zhang, Huang, Liu, & Zhang, 2019). Revealing the particle issues in these processes plays vital roles in improving electrode performance of next-generation batteries.
The results show that the Taguchi method is an effective approach for optimizing the exchange current density of lithium-ion batteries. This paper shows that the separator thickness followed by the positive electrode thickness play the major role in determining the lithium-ion batteries response.
Advanced electrode processing technology can enhance the cyclability of batteries, cut the costs (Wood, Li, & Daniel, 2015), and alleviate the hazards on environment during manufacturing LIBs at a large scale (Liu et al., 2020c; Wood et al., 2020a; Zhao, Li, Liu, Huang, & Zhang, 2019).
