摘要： A method of joining dissimilar materials having different ductility, involves two principal steps: Decoration of the more ductile material's surface with particles of a less ductile material to produce a composite; and, sinter-bonding the composite produced to a joining member of a less ductile material. The joining method is suitable for joining dissimilar materials that are chemically inert towards each other (e.g., metal and ceramic), while resulting in a strong bond with a sharp interface between the two materials. The joining materials may differ greatly in form or particle size. The method is applicable to various types of materials including ceramic, metal, glass, glass-ceramic, polymer, cermet, semiconductor, etc., and the materials can be in various geometrical forms, such as powders, fibers, or bulk bodies (foil, wire, plate, etc.). Composites and devices with a decorated/sintered interface are also provided.

摘要： Layered structures and associated fabrication methods that serve as the foundation for preparing high-operating-temperature electrochemical cells have a porous ceramic layer and a porous metal support or current collector layer bonded by mechanical interlocking which is provided by interpenetration of the layers and/or roughness of the metal surface. The porous layers can be infiltrated with catalytic material to produce a functioning electrochemical electrode.

摘要： Several synthetic additives have been used to improve the carbon coatings on LiFePO4 electrode materials. Pyromellitic acid (PA) added prior to calcination decreases the D/G ratios of the carbon produced in situ, while the use of both iron nitrate and PA results in increased sp2 character. Thus, the carbon coatings are structured with a greater fraction of graphitic character. The production of structured carbon coatings results in higher pressed pellet conductivities of LiFePO4/C composites and improved electrochemical performance of cells containing these cathode materials, although the carbon content is not necessarily increased. The combination of both ferrocene and PA used during LiFePO4 synthesis causes more carbon to be retained, although the structural characteristics are similar to that produced from the same amount of PA alone.
摘要翻译： 已经使用几种合成添加剂来改善LiFePO 4电极材料上的碳涂层。 煅烧前添加的均苯四酸（PA）降低了原位产生的碳的D / G比，而使用硝酸铁和PA也增加了sp2特性。 因此，碳涂层被构造成具有较大分数的石墨性质。 结构化碳涂层的生产导致LiFePO 4 / C复合材料的较高的压片导电率和提高含有这些阴极材料的电池的电化学性能，尽管碳含量不一定增加。 在LiFePO 4合成中使用的二茂铁和PA的组合导致更多的碳被保留，尽管其结构特征类似于仅由相同量的PA产生的结构特征。
