Beschreibung
Zusammenfassung:	The invention provides a preparation method of a Sr/Mg co-doped LaAlO3 electrolyte material battery, which comprises the following steps: preparing an LSAM electrolyte material by using Al (NO3) 3.9 H2O, La (NO3) 3.6 H2O, Sr (NO3) 2 and Mg (NO3) 2 as raw materials and citric acid and EDTA (Ethylene Diamine Tetraacetic Acid) as complexing agents through a sol-gel method; the preparation method comprises the following steps: preparing a BaCe0. 7Zr0. 1Y0. 2O3 (BCZY) proton conductor from Ba (NO3) 2, Zr (NO3) 4. 5H2O, Ce (NO3) 3. 6H2O, YN3O9. 6H2O, citric acid and EDTA (Ethylene Diamine Tetraacetic Acid) by adopting a sol-gel method; preparing an electrode material, namely coating the foam Ni with the Ni < 0.8 > Co < 0.15 > Al < 0.05 > LiO < 2-delta > (NCAL) slurry, so as to prepare the electrode material of the solid oxide fuel cell; according to the method, Ni-NCAL is used as a symmetric electrode, La1-xSrxAl0. 95Mg0. 05O3-delta is used as an electrolyte, and a battery Ni-NCAL/LSAM/NCAL-Ni or a battery Ni-NCAL/
