Web7 de set. de 2024 · The battery technology has been made great progress since LiCoO 2 was commercialized by Sony in 1990s [ 4 ]. Cathode materials as the most important component possess limited energy density. The traditional cathode materials such as LiCoO 2, Li 2 MnO 3, and LiNi 0.5 Mn 1.5 O 2 have a mature production process. Web14 de out. de 2016 · In this work, we studied thoroughly the cathode/electrolyte interface between LiCoO 2 and Li 7 La 3 Zr 2 O 12 (LLZO). It was found that the high-temperature process to fuse LiCoO 2 and LLZO induced cross-diffusion of elements and formation of the tetragonal LLZO phase at the interface.
