In-situ XRD battery test sealing box

The invention discloses an in-situ XRD battery test sealing box, and aims to solve the problem that in the prior art, dynamic change of properties such as structures of atoms or molecules inside component materials of a battery electrode material in the electrode reaction process cannot be observed or systematically analyzed. The in-situ XRD battery test sealing box is characterized in that a sealing ring (5) is fixed on the inner surface of a box cover (6); a box cover (6) is connected with a box body (2) through two connecting rods (4); a sample plate (1) is directly connected with the bottom side of the box body (2); a battery base (3) is arranged in the right center of the box body (2); an internal circuit is led out from an internal and external integrated inserting hole (7) formed in a box wall on one side of the box body (2). The in-situ XRD battery test sealing box has the advantages of reasonable structure, simple manufacturing, low cost, convenient operation and the like, the electrode material can be prevented from air, and in-situ XRD test in case of electricity charge and discharge can be achieved.
