“…41 Wei et al prepared the LiFePO 4 /C cathode with sulfonated polyether ether ketone with pendant lithiated uorinated sulfonic groups (SPEEK-FSA-Li) as binder to reduce the Li + concentration polarization and electrolyte depletion during rapid charge-discharge processes. 45 Since poly(vinylideneuoride-hexauoro propylene) (P(VDF-HFP)) polymer has higher amorphousity and lower glass transition temperature (T g ), Hu et al reported that the LiFePO 4 cathode using P(VDF-HFP) as binder showed better electrochemical performance including cycling stability and rate capability compared to the LiFePO 4 cathode using PVDF as binder. 46 However, P(VDF-HFP) polymer still does not have intrinsic ionic functionality, so that it is difficult to improve rate performance of LIBs.…”

“…In both slurry types, a high temperature oven is needed to dry out the electrodes, further increasing manufacturing costs due to the time and energy needed to fully dry. Drying time can take up to 24 h with the temperature ranging from 80–120 °C depending on the slurry type . Higher solids loading can be a way of reducing drying time but this can lead to difficulties in coating the current collector due to higher viscosities…”

Lithium‐ion battery electrodes are manufactured using a new additive manufacturing process based on dry powders. By using dry powder‐based processing, the solvent and its associated drying processes in conventional battery process can be removed, allowing for large‐scale Li‐ion battery production to be more economically viable in markets such as automotive energy storage systems. Uniform mixing distribution of the additive materials throughout the active material is the driving factor for manufacturing dry powder‐based Li‐ion batteries. Therefore, this article focuses on developing a physical model based on interfacial energies to understand the mixing characteristics of the dry mixed particulate materials. The mixing studies show that functional electrodes can be manufactured using dry processing with binder and conductive additive materials as low as 1 wt% due to the uniformly distributed particles. Electrochemical performance of the dry manufactured electrodes with reduced conductive and binder additive is promising as the cells retained 77% capacity after 100 cycles. While not representative of the best possible electrochemical performance of Li‐ion batteries, the achieved electrochemical performance of the reduced conductive and binder additive electrodes with LiCoO2 as the active material confirms the well distributed nature of the additive particles throughout the electrode matrix.

“…Once mixed, the slurry is cast onto the current collector and must be dried to create a dry porous electrode for further battery fabrication. The drying process can take a significant amount of time and energy (up to 24 h at 80-120 C), which increases the manufacturing cost of the battery electrodes [4,5]. In commercial applications, an expensive NMP recovery system is used to recover evaporated NMP due to the environmentally hazardous properties of NMP [6][7][8][9][10].…”

A new dry spraying additive manufacturing method for Li-ion batteries has been developed to replace the conventional slurry-casting technique for manufacturing Li-ion battery electrodes. A dry spray manufacturing process can allow for the elimination of the time- and energy-intensive slurry drying process needed due to the use solvents to make the electrodes. Previous studies into the new manufacturing method have shown successful fabrication of electrodes which have strong electrochemical and mechanical performance. Li-ion battery electrodes typically consist of three basic materials: active material (AM), binder particle additives (BPA), and conductive particle additives (CPA). In this paper, a discrete element method (DEM) simulation was developed and used to study the mixing characteristics of dry electrode powder materials. Due to the size of the particles being in the submicron to micron size range, the mixing characteristics are heavily dependent on van der Waals adhesive forces between the particles. Therefore, the effect the Li-ion battery electrode material surface energy has on the mixing characteristics was studied. Contour plots based on the DEM simulation results where the surface energy components of selected material types are changed were used to predict the mixing characteristics of different particle systems. For the cases studied, it is found that experimental mixing results are representative of the results of the DEM simulations.
