Embodiment 1
[0022] Take appropriate amount of chemically pure FeC 2 o 4 ?2H 2 O. Li 2 CO 3 , NH 4 h 2 PO 4 and WO 3 As a raw material, according to Li 0.99 FeW 0.01 PO 4 The atomic ratio ingredients are taken out, and 5g of the prepared raw material mixture is taken out and poured into a ball mill jar, and 2g of sucrose and 100g of steel balls are added, and then poured into the acetone solution, after the ball mill jar is immersed, the lid of the jar is tightly closed, and The planetary ball mill is used for ball milling, and the ball milling speed is set at 200r / min. After ball milling for 5 hours, take out the ball mill jar, take out the alloy powder, put it in a flat container to dry, then put the dried powder into a quartz glass tube, and Carry out vacuum sealing, put the sealed glass tube into water, if there is no air bubble, it means that the sealing is good, then put the glass tube into a high temperature furnace at 500°C for calcination, after calcination for 15 hours,...
Embodiment 2
[0024] Take appropriate amount of chemically pure FeC 2 o 4 ?2H 2 O. Li 2 CO 3 , NH 4 h 2 PO 4 and WO 3 As a raw material, according to Li 0.95 FeW 0.05 PO 4 The atomic proportion of ingredients, 10g of the prepared raw material mixture is poured into a ball mill jar, and 4g of sucrose and 200g of steel balls are added, then poured into the acetone solution, after the ball mill jar is immersed, the lid of the jar is tightly closed, and the The planetary ball mill is used for ball milling, and the ball milling speed is set at 300r / min. After ball milling for 2 hours, take out the ball mill jar, take out the alloy powder, put it in a flat container to dry, then put the dried powder into a quartz glass tube, and Carry out vacuum sealing, put the sealed glass tube into water, if there is no air bubble, it means that the sealing is good, then put the glass tube into a high-temperature furnace at 800°C for calcination, after calcination for 10 hours, take it out and cool i...
Embodiment 3
[0026] Take appropriate amount of chemically pure FeC 2 o 4 ?2H 2 O. Li 2 CO 3 , NH 4 h 2 PO 4 and WO 3 As a raw material, according to Li 0.9 FeW 0.1 PO 4 20g of the prepared raw material mixture is poured into a ball mill jar, and 5g of sucrose and 400g of steel balls are added, then poured into the acetone solution, after the ball mill jar is immersed, the lid of the jar is tightly closed, and the The planetary ball mill is used for ball milling, and the ball milling speed is set at 300r / min. After ball milling for 5 hours, take out the ball mill jar, take out the alloy powder, put it in a flat container to dry, then put the dried powder into a quartz glass tube, and Carry out vacuum sealing, put the sealed glass tube into water, if there is no air bubble, it means that the sealing is good, then put the glass tube into a high temperature furnace at 800°C for calcination, after calcination for 15 hours, take it out and cool it to get a composite lithium ion batter...
