In addition, colloidal processing advancements have been made for Si/C composite anodes for achieving >600 mA h/g capacities. New results on cobalt-free LiNi 0.8Fe 0.1Al 0.1O 2 (NFA 811) are also included and discussed in an electrode processing advantage context. Aqeous electrode processing with more » a variety of active anode and cathode materials is now a standard procedure at the DOE Battery Manufacturing R&D Facility at ORNL (BMF), including the latest processes developed for Ni-rich cathodes. This paper primarily covers major materials chemistry advancements made over the last 10 years at Oak Ridge National Laboratory (ORNL) in the space of advanced manufacturing science for LIBs with the aim of simultaneously meeting the ultimate cost target, 500 Wh/kg gravimetric energy density, 10-15-min fast charge times, and 1000 deep discharge cycles. Department of Energy (DOE) cell cost target of $80/kWh. This review contemplates the advantages and disadvantages of each of these approaches and provides a comprehensive outlook on the future of electrode = ,Īs lithium-ion battery (LIB) active material and cell manufacturing costs continue to drop with wider adoption of electric vehicles, electrode and cell processing costs remain too high in terms of reaching the ultimate U.S. 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. Simultaneously, methods to replace traditional wet processing of electrodes are being extensively researched. This review considers each of these issues and discusses which electrode slurry properties should be considered when optimizing wet slurry fabrication. 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. Specifically, wet processing of electrodes has matured such that it is a commonly employed industrial technique. As modern energy storage needs become more demanding, the manufacturing of lithium-ion batteries (LIBs) represents a sizable area of growth of the technology.
