AI Technical Summary
The challenge is to develop methods for preparing slurries containing solid electrolyte materials that maintain desired rheological properties for coating and drying without degrading the electrolyte, which is crucial for the production of solid-state electrochemical cells.
The use of specific ester solvents with Hansen Solubility Parameters, such as 2-ethyl-hexyl acetate, octyl acetate, or amyl propionate, combined with a solid electrolyte material and optional additives like binders and conductive agents, to create a stable slurry that maintains the integrity of the electrolyte during the coating and drying processes.
This approach ensures the stability of the solid electrolyte material, preventing degradation and maintaining high ionic conductivity, even after extended periods, thereby enhancing the electrochemical performance of the cell layers.
