Synthesis and Characterization of Phosphate Doped BaPr1-y(Y/Yb/Tm)yO3-δ

“…In addition to this oxyanion doping has been shown to enhance the CO2 stability of the doped Ba2(In/Sc)2O5 systems, which is attributed to the introduction of these acidic dopants reducing the basicity of the system [11][12][13][14]. These oxyanion dopants have also been shown to be able to be accommodated into a range of other perovskites, both electrolyte and electrode systems, showing that the perovskite structure is amenable to their incorporation [15][16][17][18][19][20][21][22][23].…”

Effects of sulfate modification of stoichiometric and lithium-rich LiNiO2 cathode materials

“…This methodology has attracted much interest in perovskite oxide electrodes for solid oxide fuel cells, where results illustrate that transition-metal octahedra TMO 6 can be replaced with tetrahedral MO 4 (M = Si, S, P) or trigonal planar MO 3 (C, B) to create materials with improved properties. [33][34][35][36][37][38][39][40][41] In this work, we examine the effect of sulfate modication in LiNiO 2 and Li-rich LiNiO 2 , and the corresponding effect on the structural and electrochemical properties using a combined experimental and modelling approach. The formation of Li-rich phases with Ni-rich compositions has been challenging so far, producing poorly ordered materials.…”
