Coating slurries for making anodes and cathodes of lithium batteries contain a large percentage of solid particles of different chemicals, sizes and shapes in highly viscous media. A thorough mixing of these slurries poses a major challenge in the battery manufacturing process. Several types of mixing devices and mixing methods were examined.
Typically, slurries for lithium-ion electrodes consist of a solvent, the anode or cathode active material, carbon black to ensure the electrical conductivity and a binder for the cohesion between the particles and the adhesion of the electrode layer to the current collector respectively.
4. Conclusions In this study, we introduce a novel slurry concept based on capillary suspensions for the fabrication of lithium-ion electrodes. Addition of a secondary fluid, immiscible with the main fluid of the suspension, can create a sample-spanning network controlled by capillary forces.
The manufacturing process strongly affects the electrochemical properties and performance of lithium-ion batteries. In particular, the flow of electrode slurry during the coating process is key to the final electrode properties and hence the characteristics of lithium-ion cells, however it is given little consideration.
The effect of formulation on the slurry properties, and subsequent performance in electrode manufacturing, is investigated for a lithium-ion graphite anode system.
The characteristics and performance of lithium-ion batteries typically rely on the precise combination of materials in their component electrodes. Understanding the impact of this formulation and the interdependencies between each component is critical in optimising cell performance.
