| Abstract Scope |
All-solid-state batteries (ASSBs) have attracted a strong interest in electrifying vehicles due to their improved energy density and safety characteristics compared to those of existing liquid electrolyte-based lithium-ion batteries (LIBs). Co-sintering of ceramic electrolyte and electrode is one of main-stream ways to manufacture multilayered ASSB structures. However, the fundamental science behind the formation of void and interfacial phases between ceramic electrolytes and cathode remain elusive. A novel phase-field model will be presented to simulate the co-sintering process to understand the fundamental mechanisms. Some examples including a LLZO electrolyte and a series of typical cathode materials: LiCoO2, LiFePO4, and LiMn2O4 are used to demonstrate the model. |
