Analyzed the working principle, structure and application of lithium-ion batteries

Source: 2020 - 04 - 01 but clicks: time analysis of the working principle, structure and application of lithium-ion batteries analyzed working principle, structure and application of lithium batteries. Lithium battery is rechargeable batteries, mainly rely on lithium ion move between the positive and negative. Lithium-ion batteries with high energy density, cover an area of an area small, long cycle life, lead-acid battery has been widely used in our daily life. More and more important role in the modern lithium-ion batteries, this article can solve lithium battery manufacturer for us about the operating principle, structure and application of lithium batteries. The working principle of lithium-ion battery lithium battery is a rechargeable battery, rely mainly on lithium ion move between the positive and negative. , in the process of charging and discharging lithium ion reciprocating embedded between two electrodes and embedded off: batteries, lithium ion from the anode, embedded by the electrolyte embedded negative. Discharge, on the other hand. Electrode for lithium battery is the representative of the modern high-performance batteries. The working principle of lithium ion battery is a principle of the charge and discharge. Lithium battery discharging, lithium ion and lithium ion behavior happened at the same time. The direction is the same, but the path is different. Lithium ion lithium ion from the cathode 'leap into the electrolyte,' crawl 'through the gap in curved hole,' swim to the anode, where it has reached with the combination of electronic. Lithium ion in the lithium battery charge and discharge process, from the positive to the negative to the positive movement. If we put the lithium ion battery as a rocking chair, rocking chair at both ends of the is the arctic and Antarctic battery, lithium ion is like a good athlete, rocking chair before and after the ends of the roll. Therefore, the experts to lithium ion battery has a lovely name: rocking chair batteries. The structure of the lithium battery lithium batteries on the structure of the first five pieces: the anode, cathode, electrolyte and clearance, shell and electrode leads. Main component is the structure of the lithium battery winding type and cascading. Liquid lithium battery USES the winding structure, polymer lithium battery both. The anode material: active material, conductive agent, solvent, adhesive and matrix. In lithium-ion batteries, the market capacity data is biggest, higher value-added, about 30% of the cost of lithium-ion battery, 15% lower than the gross profit margin, high above 70%. Now this batch has been used in lithium batteries positive data, the first lithium cobalt acid lithium, lithium manganese acid, nickel acid, lithium cobalt nickel manganese acid and lithium iron phosphate. Negative material: active material ( Graphite, MCMB, CMS) , adhesives, solvents, matrix. Negative data in the proportion of lithium electricity cost is low, there are mainly carbon negative data and the carbon negative data. Diaphragm: puts the diaphragm between the north and south poles, as a kind of block electrode of the device, in order to prevent direct contact of active material for the north and south poles, lithium battery short circuit. But the gap is still needs to allow charged ions through the formation of channel. The lithium battery clearance data of main products are single PP, PE, PP, PE + + ceramic coatings ceramic coating, dual-motor PP/PE, PP/PP and PP/PE. The electrolyte: shell hardware ( Steel, aluminum shell, shell plate, pole ear, insulation, insulation tape) The electrolyte is superior to the LiPF6, but the price expensive; Other have LiAsF6, but there is a lot of toxic; LiClQ, strong oxidation; Organic solvents have DEC, DMC, DME, etc. Battery shell, divided into steel shell ( Rarely used in square) Iron shell, aluminum, nickel plating, Used for cylindrical battery) , aluminum-plastic film ( Flexible packaging) And so on, the battery cover were the positive and negative terminals of the battery. Lithium battery application of planning, from the point of the development of lithium battery application market in China, the lithium battery will be more better for nickel cadmium battery and nickel metal hydride batteries or dance with them. Rapid development in the IT field, notebook, mobile phone replacement rate of not less than 15%. Growth of digital products will lead to the increase of lithium battery shipments. In addition to these portable lithium batteries, power tools, standby power supply and car power supply also shows a good development prospects
