Abstract: An additive for a positive electrode material includes an internal component and an external component. The internal component contains a silane coupling agent modified inorganic lithium salt. The external component is formed on a surface of the internal component and contains a polymer with a low melting point.

Abstract: This disclosure provides automatic analyzers and reagent wheels thereof. The reagent wheel can have one or more rings of reagent bottle seats that may be used for placing a reagent container and distributed along a circumferential direction. An included angle may be formed between a symmetrical centerline of the reagent container placed on the reagent bottle seat and a radius of a circle where the reagent wheel is located, where the included angle is not equal to zero. Compared with the situation in which the symmetrical centerline of the reagent container overlaps with the radius of the circle where the reagent wheel is located, an improved balance can be achieved between the capacity and the diametric size of the reagent wheel, thus making an improvement in meeting application requirements of the analyzers.

Abstract: The present invention relates to a disposable reaction cuvette segment for use in full automatic chemistry analyzers, which is a curved cuvette segment (1) comprising at least three open-ended cuvettes (11). Connecting webs (12) are arranged on the top surface between every two adjacent cuvettes (11) and on the upper part of the front and back sides of the cuvettes. The lower part of the cuvette (11) is an optical surface (13). Two fixing protrusions (15) of the same height arranged at the same level are provided vertically down on the top of the inner side of the curved cuvette segment (1), and inside each of these protrusions there is set a vertically oriented mounting hole (16) having a round or tapered shape. As compared with the prior art, the present invention has such advantages as simpler structure, accurate positioning and convenience for installing and replacing.
