Description

technical field

[0001] The invention relates to a spectral pool suitable for electrochemical in-situ XRD characterization, belonging to the field of spectral pools. Background technique

[0002] The structural characteristics of electrode materials determine their electrochemical performance. Therefore, the study of the degradation mechanism of the electrochemical performance of electrode materials must be carried out from the aspect of material structure characterization. Electrochemical measurement techniques, including galvanostatic charge-discharge tests, etc., can only reflect the electrochemical performance of materials, but cannot directly reflect the essential problems that lead to the electrochemical performance of materials.

[0003] Powder X-ray Diffraction (XRD) technology has always been a very important structural characterization method in the study of the crystal structure of solid materials, in terms of phase transition, stress, and structural analysis of m...
