An all-solid-state battery using an oxide-based solid-state electrolyte that has non-flammability, good ionic conductivity, and excellent (electro)chemical stability is one of the most promising systems for next-generation batteries. However, their cell integration processing faces challenges due to high-temperature requirements that leads to chemical crosstalk across interfaces, especially between an oxide cathode and an oxide solid electrolyte.
In this presentation, we will demonstrate low-temperature integration of all-solid-state batteries to overcome the interface challenges. We employed a low-melting point ceramic material, lithium-rich oxychloride, and combine lithium lanthanum zirconate with lithium cobalt oxide. We found that infiltrating the molten ceramic binder greatly improves the solid-solid contact between particles in a cathode and the interfaces between the cathode and solid electrolyte, achieving 50 mAh/g at 90°C discharge. This research will provide a new direction for all-solid-state battery processing.
