Abstract: The present disclosure relates to a cathode active material for a sodium ion secondary battery having high reversible capacity and excellent cycle characteristics, and a method for preparing the same. The cathode active material for a sodium ion secondary battery shows high reversible capacity and excellent cycle characteristics, when it is applied to a secondary battery. Therefore, when the cathode active material is used for manufacturing a cathode for a sodium ion secondary battery and the cathode is applied to a sodium ion secondary battery, the battery can substitute for the conventional expensive lithium ion secondary battery and can be applied to various industrial fields.

Abstract: An in-situ coin cell support device for transmission mode X-ray diffraction analysis capable of controlling temperature. The device includes a coin cell seating unit including a seating part for receiving an in-situ coin cell, a positive electrode tab coupled to the seating part and connected to a positive electrode of the in-situ coin cell, and a negative electrode tab coupled to the seating part and connected to a negative electrode of the in-situ coin cell, a housing having a heat-insulating function, which surrounds the coin cell seating unit such that the positive and negative electrode tabs extend outwards from the housing and which includes one side wall and an opposite side wall arranged opposite each other with the in-situ coin cell interposed therebetween, and a temperature control unit coupled to the exterior of the housing and including an inlet port, an outlet port, and a flow passage.
