[0037] Example: Preparation of NiO / apatite-type lanthanum silicate submicron-nanoporous anode functional layer
[0038] In this embodiment, the preparation of the NiO / apatite type lanthanum silicate submicron-nanoporous anode functional layer includes the following steps:
[0039]The first step: prepare functional layer powder, weigh 80nm apatite type lanthanum silicate (La 10 Si 5.8 Mg 0.2 o 26.8 ) nanopowder, 30nm NiO nanopowder, where La 10 Si 5.8 Mg 0.2 o 26.8 The nano powder is prepared according to the Chinese invention patent CN201310357158.X; absolute ethanol is added into the ball mill tank, and the weighed apatite-type lanthanum silicate nano powder and NiO nano powder are put into the ball mill tank and mixed by ball milling to obtain Suspension; Specifically, the ball material in the ball mill jar is agate;
[0040] Step 2: Pour the suspension obtained after mixing the ball mill into a container, put it into a constant temperature drying oven, dry it at 55°...
