Embodiment 1
[0021] Chemically pure FeC 2 o 4 ・2H 2 O , Li 2 CO 3 , NH 4 h 2 PO 4 , metal Mn powder and metal Ce powder as raw materials, according to Li 0.97 Ce 0.03 Fe 0.85 mn 0.15 PO 4 The atomic proportion of ingredients is 5g of the mixture. After preliminary mixing of the prepared mixture raw materials, pour them into the ball mill jar together, then add an appropriate amount of grinding steel balls into the ball mill jar, then cover the ball mill jar lid and tighten the screws, and then use the pump The air machine is used for vacuuming operation, and the operation is stopped after the air pressure in the tank is lower than 0.1 atmosphere, and then an appropriate amount of argon is filled into the ball milling tank as a protective gas, and then it is put into a planetary ball mill for ball milling. The speed is set to 200 rev / min. After ball milling for 12 hours, take off the ball mill pot and let it stand for a period of time. After the gas in the ball mill pot is releas...
Embodiment 2
[0023] Chemically pure FeC 2 o 4 ・2H 2 O , Li 2 CO 3 , NH 4 h 2 PO 4 , metal Mn powder and metal Ce powder as raw materials, according to Li 0.99 Ce 0.01 Fe 0.9 mn 0.1 PO 4 20g of the mixture with the atomic ratio of ingredients, mix the prepared mixture raw materials and pour them into the ball mill jar together, then add an appropriate amount of grinding steel balls into the ball mill jar, then cover the ball mill jar lid and tighten the screws, and then use the pump The air machine is used for vacuuming operation, and the operation is stopped after the air pressure in the tank is lower than 0.1 atmosphere, and then an appropriate amount of argon is filled into the ball milling tank as a protective gas, and then it is put into a planetary ball mill for ball milling. The speed is set to 250 rev / min. After ball milling for 11 hours, take off the ball mill pot and let it stand for a period of time. After the gas in the ball mill pot is released and decompressed, open...
Embodiment 3
[0025] Chemically pure FeC 2 o 4 ・2H 2 O , Li 2 CO 3 , NH 4 h 2 PO 4 , metal Mn powder and metal Ce powder as raw materials, according to Li 0.9 Ce 0.1 Fe 0.7 mn 0.3 PO 4 50g of the mixture with the atomic ratio of ingredients, mix the raw materials of the prepared mixture initially and pour them into the ball mill jar together, then add an appropriate amount of grinding steel balls into the ball mill jar, then cover the ball mill jar lid and tighten the screws, and then use the pump The air machine is used for vacuuming operation, and the operation is stopped after the air pressure in the tank is lower than 0.1 atmosphere, and then an appropriate amount of argon is filled into the ball milling tank as a protective gas, and then it is put into a planetary ball mill for ball milling. Set the speed at 300 rpm. After 10 hours of ball milling, remove the ball mill tank and let it stand for a period of time. After the gas in the ball mill tank is released and the pressur...
