Photo-assisted low temperature crystallization of solution-derived LiCoO2 thin film

LiCoO2 is one of the most successfully commercialized cathode materials for battery applications, owing to its excellent capacity and cycle performance. LiCoO2 exhibits two main crystallographic structures depending on the calcination temperature: low-temperature cubic spinel (Fd3m) structure, often called LT-LiCoO2, and high-temperature hexagonal layered structure (R3¯m), referred to as HT-LiCoO2. HT-LiCoO2, which generally requires a high...
