Introduction to the production process of lithium batteries
Let us briefly explain the manufacturing process of the lithium battery and the application range of the lithium battery.
Lithium battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and acts on a non-aqueous electrolyte solution. The lithium battery that appeared very early came from the great inventor Edison, and the following reaction after use: Li+MnO2=LiMnO2 This reaction is a redox reaction, discharge. Due to the very active chemical properties of lithium metal, the environmental requirements for processing, storage and use of lithium metal are very high. Therefore, lithium batteries have not been used for a long time. With the rapid development of modern science and technology, lithium batteries have now become the mainstream of the vast market. Let us briefly explain the manufacturing process of the lithium battery and the application range of the lithium battery. Brief description of the production process of lithium batteries: (1) ingredients, (2) coating, (3) filming (front stage), (4) filming (back stage), (5) cap, (6) winding, ( Seven) Welding, (8) Liquid injection, (9) Testing, (10) Packaging Following the development of microelectronics technology in the 20th century, the number of miniaturized equipment has been increasing, and the power supply has gradually increased. Requirements, and then lithium batteries have also begun to enter a large-scale practical phase. Lithium sub-primary batteries were used early and are mainly used in pacemakers. Since the self-discharge rate of lithium sub-batteries is very low, the discharge voltage is very slow, making it possible for the pacemaker to be implanted in the human body for long-term use. Lithium manganese batteries generally have a standard nominal voltage greater than 3.0 volts, which is quite suitable for those integrated circuit power supplies, commonly used in computers, calculators, watches and other places. Then a large number of lithium-ion batteries are used in mobile phones, notebook computers, power tools, electric vehicles, street light backup power supplies, navigation lights, household appliances and other places, which can indicate that lithium batteries are the largest application group in the market. The chemical properties of lithium are active. Although lithium batteries are now at the top of the competition with alkaline batteries, their process technology is complicated and the process requirements are strict. Therefore, it is difficult for some small well-known enterprises and small manufacturers to obtain in this field. With development, it is difficult to make breakthroughs in the production process. This requires the state to invest in scientific research funds to further increase the scope of lithium chemistry research.
