Abstract：This study collects in-situ X-ray diffraction(XRD)data during the charging and discharging cycles of lithium-ion batteries with different cathode and anode materials.Through the analysis of the obtained series spectra,the lithium ion intercalation and deintercalation behavior,lattice expansion and contraction,valence state transitions of various metal elements,phase transition processes and the coexistence of multiphase in the reaction process of the internal materials of the battery are studied,so as to obtain the evolution law of the microstructure and lattice parameters of the material.This analytical method is helpful to determine the key characteristics of lithium-ion batteries in different stages of the reaction process.
