Embodiment 1
[0045] Add 0.01 mol of manganese acetate into 40 mL of deionized water, heat and stir at 80°C for 1 h. Then add 0.01 mol of sodium citrate dihydrate, stir at 80° C. for 2 h, and stir at a speed of 300 rpm. Afterwards, the temperature was raised to 100° C., the stirring speed was 500 rpm, and the solution was stirred until the solution became a gel. Then move into the oven and dry at 120°C. Grind the dried precursor evenly. Then use a muffle furnace for heat treatment, and use a segmented heating method to process the sample. First heat to 350°C and keep warm for 4 hours, then heat to 950°C and keep warm for 24h. Sodium manganate product is obtained.
[0046] by attaching figure 1 It can be seen from the scanning electron microscope (SEM, 10 μm) that the prepared sodium manganate is a single crystal crystal, and the grain size is 5-30 μm; figure 2 It can be seen from the scanning electron microscope image (SEM, 1 μm) that the prepared sodium manganate has a layered struc...
Embodiment 2
[0049] Add 0.1 mol of manganese acetate into 100 mL of deionized water, heat and stir at 80°C for 1 h. Then 0.12 mol of sodium citrate dihydrate was added, stirred at 80° C. for 2 h, and the stirring speed was 500 rpm. Afterwards, the temperature was raised to 100° C., the stirring speed was 500 rpm, and the solution was stirred until the solution became a gel. Then move into the oven and dry at 150°C. Grind the dried precursor evenly. Then use a muffle furnace for heat treatment, and use a segmented heating method to process the sample. First heat to 350°C and keep warm for 4 hours, then heat to 800°C and keep warm for 24h. Sodium manganate product is obtained. The SEM, XRD and electrical performance tests of the product prepared in Example 2 are all similar to the sample prepared in Example 1.
Embodiment 3
[0051] Add 0.1 mol of manganese sulfate to 100 mL of deionized water, heat and stir at 90°C for 1 h. Then add 0.12 mol of sodium citrate dihydrate, stir at 90° C. for 2 h, and stir at a speed of 500 rpm. Afterwards, the temperature was raised to 100° C., the stirring speed was 500 rpm, and the solution was stirred until the solution became a gel. Then move into the oven and dry at 120°C. Grind the dried precursor evenly. Then use an argon atmosphere for heat treatment, and use a segmented heating method to process the sample. First heat to 400°C and keep warm for 4 hours, then heat to 850°C and keep warm for 12h. Sodium manganate product is obtained.
[0052] The SEM, XRD and electrical performance tests of the product prepared in Example 3 are all similar to the sample prepared in Example 1.
