    摘要: A method for carrying out solid state reactions under reducing conditions is provided. Solid state reactants include at least one inorganic metal compound and a source of reducing carbon. The reaction may be carried out in a reducing atmosphere in the presence of reducing carbon. Reducing carbon may be supplied by elemental carbon, by an organic material, or by mixtures. The organic material is one that can form decomposition products containing carbon in a form capable of acting as a reductant. The reaction proceeds without significant covalent incorporation of organic material into the reaction product. In a preferred embodiment, the solid state reactants also include an alkali metal compound. The products of the method find use in lithium ion batteries as cathode active materials. Preferred active materials include lithium-transition metal phosphates and lithium-transition metal oxides. In a preferred embodiment, the reaction product contains carbon particles intimately mixed among crystals of the active materials.

    摘要: A foldable hula hoop structure includes multiple arcuate connecting members combined with each other. Each of the arcuate connecting members includes two opposite flexible main bodies combined with each other. Each of the two opposite main bodies has a first end and a second end respectively provided with convex portions and mating concave portions, so that any two adjacent arcuate connecting members may be combined with each other by engagement of the convex portions with the mating concave portions. Each of the convex portions and the mating concave portions is formed with a through hole for passage of a first locking member which is locked with a second locking member, so that any two adjacent arcuate connecting members may be combined with each other by the first locking member and the second locking member.

    摘要: A sandal device has an outsole, an air cushion, and an insole. The air cushion has two periphery flanges, a periphery spacing, a plurality of hollow protrusions, and a plurality of hollow sockets. An elastic woven fabric and a shock-absorbing band are inserted in the periphery spacing of the air cushion. The shock-absorbing band has two periphery recesses for receiving the periphery flanges of the air cushion. Each of the hollow protrusions has a groove for receiving a magnetic block and a collar. A coiled spring has a lower portion inserted in the respective hollow socket and an upper portion inserted in the respective collar.
