Synchrotron radiation X-ray absorption spectrum and mass spectrum combined battery device and test method

The invention discloses a synchrotron radiation X-ray absorption spectrum and mass spectrum combined battery device and a test method. A main substrate is used as a test cavity and is provided with anion battery, an air inlet pipeline and an air outlet pipeline, the air outlet pipeline is communicated with a mass spectrometer through an air outlet pipe, and a stainless steel spring and a rear test window sheet are clamped between the ion battery and a stainless steel pipe seat. The upper cover is provided with a front test window sheet for X-rays to penetrate through the anode material, and the lower cover is connected with the main substrate and clamps the stainless steel tube seat through a sealing tooth socket; due to the fact that the opposite penetrating windows are adopted to penetrate through the anode material through X-rays to conduct in-situ XAS, the holes are formed in the two sides of the main substrate to be communicated with the mass spectrometer, and the ion battery inthe closed space is charge
