Lithium iron phosphate dryer

Overview of lithium iron phosphate dryer engineering

  Lithium iron phosphate is a new type of electrode material for lithium-ion batteries. Its characteristics are large discharge capacity, low price, non-toxic, and does not cause environmental pollution.

  The performance of lithium-ion batteries mainly depends on the positive and negative electrode materials. As the positive electrode material of lithium-ion batteries, lithium iron phosphate has incomparable safety performance and cycle life compared to other materials, which are also important technical indicators for power batteries. Lithium iron phosphate cathode material makes it easier to use in series for large capacity lithium-ion batteries. To meet the needs of frequent charging and discharging of electric vehicles. It has the advantages of non-toxic, good safety performance, wide source of raw materials, low price, and long service life, making it an ideal positive electrode material for the new generation of lithium-ion batteries.

  On the basis of years of accumulated experience in the design and manufacturing of spray dryers, our company has set foot in the research of this product from the production of new energy materials of lithium iron phosphate. Through the actual combat of a large number of customer projects, we have constantly summarized, improved and optimized. spray drying of lithium iron phosphate has become a mature experience in design, manufacturing, construction and control operations.

Working principle of lithium iron phosphate dryer

  The spray dryer is a drying process that disperses the raw liquid into droplets with an atomizer, and obtains powdered products by directly contacting the droplets with hot air (or other gases). The feed liquid can be solution, emulsion or suspension, or molten liquid or paste. Dry products can be made into powder, granular, hollow balls, or agglomerates as needed.

  The high-speed centrifugal spray dryer for battery materials is applied to the drying production of water-soluble liquid materials of lithium iron phosphate cathode materials for lithium batteries. The high-speed centrifugal spray atomization technology is used to obtain spherical particles with uniform particle size, compact structure and good fluidity while realizing continuous drying production. To a large extent, the high-speed centrifugal atomization technology can effectively improve or increase the stacking density of lithium iron phosphate cathode materials, To meet the quality requirements of 3-5 μ m monomer particles and 0.5% moisture content in the finished product, magnetic filtration technology is applied to effectively avoid the doping of iron ion impurities in the production process, achieve material purity, and maintain the conductivity of the positive electrode material. The recycling of waste heat gas can also achieve the production goal of energy conservation and emission reduction, in line with the transformation of energy-saving, emission reduction, and low-carbon production methods advocated by the country. To maintain production safety, this machine adopts pulse dust removal cooling protection technology, and achieves cooling protection safety interlock under intelligent control operation. The comprehensive application of innovative technologies provides basic equipment and technical support for the industrial production of positive electrode materials for new energy lithium batteries in China, making it an ideal new material drying equipment.
