Battery for in-situ XRD (X-Ray Diffraction) test as well as preparation method and application of battery

The invention belongs to the technical field of battery in-situ testing, and particularly relates to a battery for in-situ XRD testing and a preparation method and application thereof. The battery comprises a positive electrode, a negative electrode, a diaphragm and electrolyte, the positive electrode and the negative electrode do not comprise current collectors; the positive electrode is coated on one side of the diaphragm; and the negative electrode is arranged on one side, far away from the positive electrode, of the diaphragm. The battery for the in-situ XRD test, provided by the invention, can realize a relatively good charge and discharge effect, is widely applicable to in-situ XRD test devices in the market, can achieve the purpose of eliminating current collector interference in the in-situ XRD test process, and can more accurately reflect the change of a material structure in the charge and discharge process. 本发明属于电池原位测试技术领域，具体涉及一种用于原位XRD测试的电池及其制备方法与应用。该电池包括正极、负极、隔膜和电解液；所述正极和负极均不包括集流体；所述正极涂覆于所述隔膜的一侧；
