Materials processing for lithium-ion batteries

▶ This paper briefly reviews materials-processing for lithium-ion batteries. ▶ Materials-processing is a major thrust area in lithium-ion battery. ▶ Advanced materials-processing can improve battery performance and energy density. ▶ It also can improve battery's calendar life and decrease cost. Extensive efforts have been undertaken to develop and optimize new materials for lithium-ion batteries to address power and energy demands of mobile electronics and electric vehicles. However, the introduction of large-format lithium-ion batteries is hampered by high cost, safety concerns, and deficiencies in energy density and calendar life. Advanced materials-processing techniques can contribute solutions to such issues. From that perspective, this work summarizes the materials-processing techniques used to fabricate the cathodes, anodes, and separators used in lithium-ion batteries.
