Publication number: 20140287341Abstract: A novel modified anode/electrolyte structure for a solid oxide electrochemical cell is an assembly comprising (a) an anode consisting of a backbone of electronically conductive perovskite oxides selected from the group of doped strontium titanates and mixtures thereof, (b) a scandia and yttria-stabilised zirconium oxide electrolyte and (c) a metallic and/or a ceramic electrocatalyst in the shape of interlayers incorporated in the interface between the anode and the electrolyte. This assembly is first sintered at a given temperature and then at a lower temperature in reducing gas mixtures. These heat treatments resulted in a distribution of the metallic and/or ceramic interlayers in the electrolyte/anode backbone junction taking place.Type: ApplicationFiled: October 23, 2012Publication date: September 25, 2014Applicant: Technical University of DenmarkInventors: Mohammed Hussain Abdul Jabbar, Jens Høgh, Eugen Stamate

Publication number: 20140255603Abstract: A surface coating method and a method for reducing irreversible capacity loss of a lithium rich transitional oxide electrode are disclosed herein. In an example of the surface coating method, a dispersion of a lithium rich transitional oxide powder and an oxide precursor or a phosphate precursor in a liquid is formed. The liquid is evaporated. The forming and evaporating steps are carried out in the absence of air to prevent precipitation of the oxide precursor or the phosphate precursor. Hydrolyzation of the oxide precursor or the phosphate precursor is controlled under predetermined conditions, and an intermediate product is formed. The intermediate product is annealed to form an oxide coated lithium rich transitional oxide powder or the phosphate coated lithium rich transitional oxide powder.Type: ApplicationFiled: March 5, 2013Publication date: September 11, 2014Applicant: GM Global Technology Operations LLCInventors: Qiangfeng Xiao, Mei Cai
