As modern energy storage needs become more demanding, the manufacturing of lithium-ion batteries (LIBs) represents a sizable area of growth of the technology. Specifically, wet processing of electrodes has matured such that it is a commonly employed industrial technique. 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. This review considers each of these issues and discusses which electrode slurry properties should be considered when optimizing wet slurry fabrication. Simultaneously, methods to replace traditional wet processing of electrodes are being extensively researched. Some of these novel electrode manufacturing techniques prioritize solvent minimization, while others emphasize boosting energy and power density by thickening the electrode and, subsequently, creating an organized pore structure to permit faster ion diffusion. This review contemplates the advantages and disadvantages of each of these approaches and provides a comprehensive outlook on the future of electrode manufacturing.
