The conventional wet electrode manufacturing process consists of mixing, coating, drying, calendaring, post-drying, and cell assembly steps, as shown in Fig. 1 [2, 3]. The wet process follows the essential step of a slurry formation consisting of active materials, binders, conductive additives, and solvents.
The electrode manufacturing procedure is as follows: battery constituents, which include (but are not necessarily limited to) the active material, conductive additive, and binder, are homogenized in a solvent. These components contribute to the capacity and energy, electronic conductivity, and mechanical integrity of the electrode.
An electrode is where the electrochemical reactions throughout the charging and discharging process occur, which is a crucial part of a battery. As a vital part of a battery, an electrode is essential to the storage and discharge of the battery.
Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
Electrode final properties depend on processing steps including mixing, casting, spreading, and solvent evaporation conditions. The effect of these steps on the final properties of battery electrodes are presented. Recent developments in electrode preparation are summarized.
Despite its widespread acceptance, wet processing of electrodes faces a number of problems, including expensive and dangerous solvent recovery, cut-off waste, coating inconsistencies, and microstructural defects due to the solvent drying process.
