Provided are a method for processing antiperovskite solid electrolytes, and solid electrolytes, batteries and vehicles. The method comprises: drying Li 3 OX powder; and carrying out a ballmilling treatment on the dried Li 3 OX powder.
After ballmilling in water, the calcined powder of composition A which has pure perovskite phase (Fig. 1) was changed to a combination of perovskite BaPbO3, BaCO3 and PbO2 as shown in Fig. 6(a). The decomposition of BaPbO3 results in the high resistivity of the corresponding sintered specimens. In addition, the resulting PbO2 phase Fig. 6.

The effect of cerium doping on perovskite structure and its gas sensing properties was then evaluated. Cedoped formulations showed a saturation point at 10 at.% in the perovskite structure. The optimum CO sensing temperature for doped formulation was found to be 100°C compared to 130°C for pure perovskite.
Perovskite nanocrystals are a class of semiconductor nanocrystals, which exhibit unique characteristics that separate them from traditional quantum dots. Perovskite nanocrystals have an ABX 3 composition where A = cesium, methylammonium (MA), or formamidinium (FA); B = lead or tin; and X = chloride, bromide, or iodide.. Their unique qualities largely involve their unusual bandstructure which ...
