Lithium ion batteries have achieved extensive applications in portable electronics and recently in electronic vehicles since its commercialization in 1990s. The vast applications of lithium ion batteries are not only derived from the innovation in electrochemistry based on emerging energy materials and chemical engineering science, but also the tec. ••The basic principles of materials processing for lithium ion batteries••The roles of slurry mixing and coating, electrode drying, and calendering••Advancing powder technologies and related advanced energy materialsLithium ion batteriesComposite electrode processingPowder technologySlurry coating and dryingThe rechargeable batteries have achieved practical applications in mobile electrical devices, electric vehicles, as well as grid-scale stationary storage (Jiang, Cheng, Peng, Huang, & Zhang, 2019; Wang et al., 2020b). Among various kinds of batteries, lithium ion batteries (LIBs) with simultaneously large energy/power density, high energy efficiency, and effective energy retention rate after long-term cycles are considered as the best-performing energy storage systems, especially for the recently emerging electric vehicles (Cai et al., 2020; Tian et al., 2019; Wang et al., 2019a).Since Sony Corporation manufactured the first-generation commercial LIBs in 1990s, extensive efforts have been devoted to boost the battery cycling performance mainly on the innovation in materials electrochemistry and processing technology (Armand & Tarascon, 2008; Liang et al., 2019; Liu et al., 2020a). Great progress has been achieved in materials innovations from LiFePO4, LiCoO2, to LiNi1−x−yCoxMnyO2 (x = 1/3, y = 1/3: NCM111; x = 0.3, y = 0.2: NCM532; x = 0.2, y = 0.2: NCM622; x = 0.1, y = 0.1: NCM811) for the cathode, graphite to silicon/graphite hybrid for the anode, liquid non-aqueous electrolyte to the solid-state electrolyte (Hao, Yang, Luo, Tian, & Shan, 2018; Lu et al., 2020; Ou, Zou, Jin, Wu, & Wang, 2020). The mixing state and microstructures of cathode, anode, binder, and conductive particles are highly. Liquid slurry is the most frequently used platform to fabricate the electrode materials mainly owing to its low cost and high processibility (Väyrynen & Salminen, 2012). The formulation and properties of electrode slurries determine the quality of the resulted electrode film. A uniform electrode film can be achieved only when the electrode slurry i.
