The chemophysical properties of slurries, which are influenced by the interaction among active materials, conductive additives, and polymer binders in the slurry solvent, play a key role in determining the performance of lithium-ion secondary batteries , .
The onset of a parasitic side reaction referred to as lithium plating strongly depends on the micro-structure of the batteries’ anode. In this study, a methodology is introduced that allows to investigate the influence of the slurry preparation on electrode properties and the resulting fast charging performance of graphite anodes.
Our work might assist in the production of high-performance Li-ion batteries that are made using an electrode slurry. The development of new materials and the understanding of the microstructure formation of electrodes have become increasingly important for improving Li-ion battery performance.
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 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.
