Introduction to the Synthesis of LiFePO4 Lithium iron phosphate is a lithium-ion battery electrode material with the chemical formula LiFePO4 (LFP), which is mainly used in various lithium-ion batteries. It is characterized by large discharge capacity, low price, non-toxicity, and no environmental pollution, but low energy density, which affects the capacitance.   The synthetic method of lithium iron phosphate: 1. Solid-phase synthesis (1) High-temperature solid-phase reaction method: the most common and mature synthesis method at this stage. The nitrogen-protected push-plate furnace, mesh belt furnace, and rotary furnace are used for sintering. (2) Carbothermal reduction (CTR): The synthesis method is simple, easy to operate, and the price of raw materials is low. It is suitable for large-scale production. (3) Microwave synthesis method: the synthesis time is short, the energy consumption is low, and it is suitable for laboratory research. (4) Mechanical alloying method: 2. Liquid phase synthesis method: (1) Liquid phase co-precipitation method, (2) Sol-gel method, (3) Hydrothermal synthesis method 3. Other synthesis methods: spark plasma sintering technology, spray thermal decomposition technology and pulsed laser deposition technology are also used for the synthesis of lithium iron phosphate.   The performance of lithium-ion batteries mainly depends on the positive and negative electrode battery materials, and its safety performance and cycle life are unmatched by other materials, which are also the most important technical indicators of power batteries. 1C charge and discharge cycle life up to 2000 times. Single-cell battery overcharge voltage 30V will not burn, puncture will not explode. The lithium iron phosphate cathode material makes large-capacity lithium-ion batteries easier to use in series. In order to meet the needs of frequent charging and discharging of electric vehicles. It has the advantages of non-toxicity, non-polluting, good safety performance, wide source of raw materials, low price, long life, etc. It is an ideal cathode material for a new generation of lithium-ion batteries.

According to the inner layer AL/PP composite method, the Aluminum Laminated Film process can be divided into two types: thermal method and dry method. The advantages of the dry process are that the product has fewer appearance defects, good deep drawing performance, low equipment investment threshold, simple process and easy to master, but limited by PP glue, its interlayer peeling force and electrolyte resistance are relatively weak; The advantage of the method is that it has excellent electrolyte resistance and water resistance. The disadvantage is that the residual thermal stress and the extrusion stress between the rollers during the high-temperature and high-pressure molding process result in the relative deterioration of its appearance and deep-drawing performance. Mingguan Lithium  Film has made technological innovations in raw materials and manufacturing processes, creatively developed dry-heat composite process technology, and took into account the advantages of thermal method in terms of electrolyte resistance and water resistance, making aluminum-plastic film forming in deep drawing. , Appearance, electrolyte resistance and water resistance and other comprehensive performance has been improved. Aluminum Laminated Film  products have many performance advantages such as excellent deep drawing performance, good electrolyte resistance, good product appearance, good insulation, strong heat resistance, high heat seal strength, humidity and heat aging resistance, and high and low temperature resistance.

Carbon nanotubes are used as anode material for lithium-ion batteries and as an excellent conductive agent for lithium batteries. The effective dispersion of CNT (carbon nanotubes) in solvents plays a vital role in the conduction of lithium batteries. However, due to the extremely large aspect ratio of CNT, entanglement and agglomeration are very easy to occur, and it is difficult to disperse, which affects the performance of its electrical conductivity. The traditional CNT slurry production line is a plan with a sand mill as the core equipment, and uses multiple rough grinding and then multiple fine grinding to perform multiple grindings to cut off the entanglement between the carbon tubes and break up Reunion. However, due to the high viscosity of the CNT slurry, the grinding efficiency of the sand mill is severely reduced, resulting in long grinding time, high energy consumption, large floor space, and low overall efficiency. Therefore, Shangshui Intelligent pioneered the CNT pulping and dispersion system with a vertical media grinding and dispersing machine as the core equipment, which can carry more than 30 times the grinding flow rate of a traditional sand mill. On the one hand, it can form a complex flow field with drastic changes and greatly improve Grinding efficiency and temperature rise can be well controlled at the same time. On the other hand, the equipment can also use larger grinding beads to achieve a good dispersion effect, thereby effectively overcoming the impact of high slurry viscosity on the grinding efficiency, and preventing excessive pulverization of CNT from affecting its electrical conductivity. Compared with the traditional CNT production line, the new high-efficiency CNT pulping and dispersion system based on this core equipment has the comprehensive advantages of large grinding flow, high energy density, good product uniformity, high overall efficiency, and convenient disassembly and washing.

How does the specific energy of the LFP battery exceed 180wh/Kg? Will monomer specific energy exceeding 180Wh/kg become a new watershed in power battery product technology? Recently, the Ministry of Industry and Information Technology issued the "Lithium-ion Battery Industry Specification Conditions (2021 Edition)", Among them, the "Specification Conditions (2021)" mentioned that for the newly constructed power battery project, the energy density of the energy-type power battery project should be ≥180Wh/kg, and the energy density of the battery pack should be ≥120Wh/kg. In addition, the "Specification Conditions (2021)" also set requirements for the performance of expansion projects such as cathode materials, anode materials, electrolytes, and separators. At present, the energy density of mainstream ternary battery cells produced in the industry is generally above 210Wh/kg, while the energy density of mainstream LFP battery cells is generally below 180Wh/kg. This means that once the technical indicators are implemented, they will have a certain impact on the industrialization of LFP batteries. Industry insiders believe that, from a technical point of view, the energy density of LFP cells can be achieved beyond 180Wh/kg, but from the point of view of industrialization, it still has certain technical difficulties for power battery companies. For power battery companies, there are mainly the following paths to achieve the energy density of LFP batteries exceeding 180Wh/kg: One is to optimize the material system, such as upgrading the cathode material from lithium iron phosphate to lithium iron manganese phosphate, adopting silicon-doped lithium supplement technology, introducing new electrolytes and ultra-thin copper foil, etc., to increase the energy density of the cell. The second is to optimize the cell structure design, increase the size of the cell to increase the battery capacity, increase the capacity of a single cell to at least 180Ah, and use lightweight technology to reduce the weight of the cell.

Battery stacking process is mainly used for pouch cell and Aluminum case battery. The stacking process uses multi-pole pieces in parallel to make the internal resistance of the battery smaller and the charging efficiency higher; and the heat generated during the charge and discharge cycle is relatively small and more uniform, and the battery safety is higher. In addition, the lamination process makes the internal space of the battery more fully utilized, and the      battery energy density is relatively larger. Therefore, the lamination process is favored by the intelligent manufacturing of lithium batteries
