The production process of lithium iron phosphate is:Lithium iron phosphate batteryThe assembly production process is divided into three main sections , one is pole piece production and the other is electric core manufacturing and the third is battery assembly. In the assembly and production process of lithium iron phosphate batteries, the production of pole pieces is the basis and the production of battery cells is the core. Battery assembly is related to the quality of the finished lithium battery. Select the appropriate battery cell. Battery cell type, voltage and internal resistance must match. Please balance the battery cells before assembly. Cut the electrodes and drill holes.
Lithium iron phosphateMain battery materials
It existsThere are four important raw materials for the production of lithium iron phosphate batteries, namely positive electrode materials, negative electrode materials, electrolytes and separators. Among cathode materials, the most commonly used materials are lithium cobalt oxide, lithium manganate, lithium iron phosphate and ternary materials. The cathode material occupies an important part, because the performance of the cathode material directly affects the performance of the lithium-ion battery, and its cost also directly determines the cost of the battery.
Among the negative electrode materials, the current negative electrode materials are mainly natural graphite and artificial graphite. As one of the four main components of lithium iron phosphate batteries, negative electrode materials play an important role in improving the capacity and performance.battery cycle challenges, and are at the heart of the midstream lithium-ion battery industry.
Market-oriented membrane materials are mainly polyolefin membranes based on polyethylene and polypropylene. In the structure of lithium-ion batteries, the separator is one of the key internal components. The performance of the separator determines the interface structure, internal resistance, etc. of the battery and directly affect the capacity, cycle and safety performance of the lithium-ion battery. Excellent separators play an important role in improving the overall performance of. battery.
The electrolyte is generally prepared from high purity organic solvents, lithium salts of electrolyte, necessary additives and other raw materials under certain conditions and in certain proportions. The electrolyte serves to conduct ions between the positive and n electrodesnegative impacts of lithium ion batteries, ensuring that lithium iron phosphate batteries obtain the advantages of high voltage and high specific energy.
