  • Patent number: 10829413
    Abstract: A process for producing a highly calcined and uniformly calcined product from a feedstock. The process comprising the steps of grinding the feedstock to powder, preheating the powder, and calcining the powder in a reactor plant that comprises a number of reactor segments in which a flash calciner is used in each progressive reactor segment to incrementally react the powder by raising the temperature in each segment. The last segment may be a high-temperature reactor that has a controlled residence time and temperature that may allow controlled finishing of the calcination process to achieve a desired degree of calcination and sintering of the product; and cooling of the product.

  • Publication number: 20150044621
    Abstract: In a substrate treatment process, substrates are moved by a transporting device in a transporting direction through a substrate treatment installation having a number of chambers. The substrates are moved by transporting sections of the transporting device driven independently of one another. The transporting sections are driven such that, if substrates dwell temporarily in the transporting section, they are moved back and forth. Stresses in a substrate brought about by differing inputs of heat as a result of both process-induced and malfunction-induced dwell times of the substrate in a chamber are reduced by compensating within the chamber for a structurally brought about input of heat into the substrate, varying periodically over the length of the chamber, during temporary dwelling of the substrate in the chamber by moving the substrate back and forth over at least one period of the heat input by a change of the transporting direction.

    Abstract: An electrode comprising a cast-film architecture wherein a silicon-based polymer precursor is cast on to a current collector directly from the liquid, and processed in-situ to create a high performance anode for lithium ion batteries. In this in-situ process the liquid polymer is cross-linked and pyrolyzed to create a cast-film-anode architecture. The cast-film architecture is distinctly different from the conventional powder-based ex-situ process whereby the polymer precursor is made into powders by a ex-situ process; with these powders being then combined with conducting agents and binders to create a paste which is screen printed on a current collector to produce electrode with a powder-anode architecture. The cast-film architecture obviates the need for conducting agents and binders, simplifying the production process for the anode, without a loss in performance. The energy capacity per unit volume of the anode material is two to ten times greater for the cast architecture.

  • Publication number: 20110195343
    Abstract: A solid oxide fuel cell (SOFC) or SOFC sub-component comprising a YSZ solid oxide electrolyte layer (10), a LSCF cathode layer (14) and a mixed phase layer (18) comprising at least zirconia and ceria between the electrolyte layer and the cathode layer, with the cathode layer in direct contact with the mixed phase layer, that is with no ceria, other than in the mixed phase layer, between the cathode layer and the electrolyte layer. One method of forming the SOFC or sub-component comprises applying a layer of ceria on the electrolyte layer (10), heating the electrolyte and ceria layers to form the mixed phase layer (18), and removing excess ceria from the surface of the mixed phase layer before applying the cathode layer (14).
