Abstract: A positive electrode active material including a first lithium composite oxide particle including a secondary particle formed by aggregation of one or more primary particles, and a coating oxide occupying at least a part of at least one of surfaces of the secondary particle, grain boundaries between the primary particles, or surfaces of the primary particles, the positive electrode active material satisfying an equation of 1.3?a/b?3.0, wherein a represents a max peak intensity at 2theta=44.75° to 44.80° and b represents a max peak intensity at 2theta=45.3° to 45.6° in X-ray diffraction (XRD) analysis using Cu K? radiation.

Abstract: The present disclosure relates to a frame packaging box for packaging frames. The frame packaging box includes a box comprising an accommodating space for accommodating frames, a plurality of supporters stacked up and down in the accommodating space to support portions of the frames, and a guide rail disposed on an inner surface of the box to guide the up-down movement of the plurality of supporters.

Abstract: A humid air forming device, which cools an object to be measured to a predetermined temperature, and which sprays humid air having a predetermined temperature to the cooled object to be measured, thereby forming moisture particles on the surface of the object to be measured, and a measurement system including the same. The humid air forming device includes a cooling unit that cools the object to be measured to a first temperature or lower; and a humid air supply unit that forms humid air having a second temperature, which is higher than the first temperature, and spraying the humid air toward the surface of the cooled object to be measured, thereby forming moisture particles on the surface of the cooled object to be measured.
