, Photo source: KERI, All-solid-state batteries have become the next generation battery technology that has attracted much attention due to their extremely low risk of fire or explosion.
However, compared to traditional batteries based on liquid electrolytes, all-solid-state batteries require more advanced technology due to their solid-state characteristics, making their manufacturing more challenging.
It is well known that effective mixing and dispersion of cathode active materials with solid electrolytes, conductive additives and binders is one of the challenges in manufacturing composite electrodes.
Its manufacturing must meet strict conditions, such as creating channels (paths) that promote efficient transport of electrons and lithium ions, and ensuring low interface resistance at the cathode-electrolyte interface.
