Embodiment 1
[0039] 1. Synthesis of LSCF powders with different particle sizes
[0040] Take La(NO 3 ) 3 ·6H 2 O, Sr(NO 3 ) 2 , Co(NO 3 ) 3 and Fe(NO 3 ) 3 9H 2 O as a raw material, La was synthesized by a sol-gel method 0.6 Sr 0.4 co 0.2 Fe0.8 o 3 (LSCF) powder, the particle size of the powder obtained after full ball milling and dispersion is 0.1-0.3 μm; 2 o 3 , SrCO 3 , CoCO 3 and Fe 2 o 3 As raw material, (LSCF) powder was synthesized by gel injection molding process, and the particle size of the synthesized powder was 0.6-1 μm; La 2 o 3 , SrCO 3 , CoCO 3 and Fe 2 o 3 As a raw material, the particle size of LSCF powder is synthesized by a solid-state method with a particle size of 1-2 μm.
[0041] 2. Slurry Preparation
[0042] (1) Use LSCF powder with a particle size of 0.1-0.3 μm to form a mixed powder with pore-forming agent graphite in a mass ratio of 1:0.1, add organic solvent ethanol and dispersant, ball mill for 20 hours, and then add plasticizer, After...
Embodiment 2
[0058] Embodiment 2: As described in Embodiment 1, the difference is that the gradient cathode material is strontium manganate lanthanum La x Sr 1-x MnO 3-δ (LSM), the sintering temperature is 1100°C, and it is kept for 2 hours and naturally cooled.
