WebMay 15, 2024 · It is accepted that in the fully delithiated state, the diameter of the HF-depressed semicircle is mainly ascribed to the intrinsic electronic resistance and the contact resistance (materia–material and material–current collector) while the LF inclined line is attributed to the lithium ion diffusion within the electrode [35,36]. WebNov 3, 2024 · This superior electrochemical performance results from the effective surface modification with LiAlSiO 4, which not only stabilizes the surface structure in the deeply delithiated state as a physical protective layer, but also improves the stability of the bulk structure by forming a solid-solution phase LiAl x Co 1–x O 2.
