Lithium iron phosphate
The manufacturing process of lithium iron phosphate powder includes the following steps:
1. Ingredients: Prepare raw materials such as phosphorus source, iron source, lithium source, carbon source, etc., such as iron phosphate, lithium carbonate, glucose, etc.
2. Grinding: Put the raw materials into the grinder in a certain order, add an appropriate amount of water for mixing and stirring, and grind into a mixed liquid.
3. Dispersion: transfer the ground mixture to the disperser, add an appropriate amount of pure water, adjust the stirring speed, fully stir and disperse for 1 2 hours, and wait for the pump to be pumped into the spray drying equipment.
4. Spray drying: The dispersed materials are dried through spray drying equipment to obtain lithium iron phosphate powder.
The following points need to be paid attention to during the production process:
1. When batching, it is necessary to strictly control the weight and proportion of materials to ensure the stability and purity of raw materials.
2. During the grinding process, it is necessary to control the grinding time and the speed of the grinding machine to ensure the uniformity and fineness of the mixed liquid.
3. In the process of dispersion, it is necessary to adjust the stirring speed and time to ensure that the material is fully dispersed and mixed evenly.
4. In the process of spray drying, it is necessary to control the drying temperature and time to ensure the dryness and particle size distribution of the powder.
In short, the manufacturing process of lithium iron phosphate powder needs to strictly control the parameters and operation details of each link to ensure the quality and stability of the product.
