Cathode for Thin-Film Lithium-Ion Batteries
Thin-film lithium-ion batteries (LIBs) have attracted considerable attention for energy storage device application owing to their high specific energy compared to conventional LIBs. However, the significant breakthroughs of electrochemical performance for electrode materials, electrolyte, and electrode/electrolyte interface are still highly desirable. This chapter firstly gives an overview of cathode materials including lithium-containing cathode (e.g., LiCoO2, LiMn2O4, LiFePO4, LiNi1−x−yMnxCoyO2, LiNi0.5Mn1.5O4) and lithium-free cathode (e.g., vanadium oxides) for LIBs in terms of specific capacity, energy density, working voltage, cycling life, and safety. In the meanwhile, the existing drawbacks and limitations of various battery chemistries are also analyzed. Furthermore, some modification strategies for these cathode materials have also been discussed for improving electrochemical performance. Finally, the thin-film Li-ion battery applications of these cathode materials are summed up toward next-generation flexible and high-energy devices.
