Abstract Scope |
A promising method for improving capacities of lithium-ion batteries (LIBs) for higher power applications is to combine a high-voltage cathode material with a solid electrolyte to produce an all-solid-state battery. With this aim in mind, we prepared thin films of high-voltage spinel-type cathode Li(Ni,Mn)2O4 with A-site deficient perovskite electrolytes (La,Li)TiO3 and (La,Li)NbO3 utilizing a chemical solution deposition method with metal alkoxide precursors. After optimizing the processing conditions, the film quality, interfacial structure and orientation relationship between cathode and electrolyte were characterized using a variety of scanning transmission electron microscopy techniques up to atomic resolution. The results show that dense films with well-defined epitaxial relationships were formed which are expected to support high charge/discharge rates and high capacities. |
