Introduction to the production process of lithium battery

A lithium battery is a battery that is made of a lithium metal or a lithium alloy as a negative electrode material and acts on a nonaqueous electrolyte solution. The lithium battery that appeared very early was from the great inventor Edison, the following reaction after use: Li + MnO2 = LiMnO2 the reaction is a redox reaction, discharge. Due to the very active chemical properties of lithium metal, the environmental requirements for lithium metal processing, storage and use are very high. Therefore, lithium batteries have not been used for a long time. With the rapid development of modern science and technology, the current lithium battery has become the mainstream of the vast market. Let us briefly explain the manufacturing process of lithium batteries and the application range of lithium batteries.

Brief description of the production process of lithium battery:

With the development of the technology of the 20th century microelectronics, the miniaturized equipment is constantly increasing, and the power supply is put forward very high requirements. Then the lithium battery has begun to enter a large-scale practical stage.

Lithium primary batteries have been used early, mainly in cardiac pacemakers. Because the self-discharge rate of lithium-ion batteries is very low, the discharge voltage is very slow, making it possible for the pacemaker to be implanted in the human body for a long time.

Lithium-manganese batteries generally have a standard voltage of more than 3.0 volts, which is quite suitable for those integrated circuit power supplies, and is commonly used in computers, calculators, watches and the like.

Then a large number of lithium-ion batteries are used in mobile phones, notebook computers, power tools, electric vehicles, street lamp backup power supplies, navigation lights, household appliances, etc., which can explain that lithium batteries are the largest application group in the market.

Although lithium battery has gained the upper hand in the competition with alkaline battery, its process technology is complex and strict. Therefore, it is difficult for some small well-known enterprises and small manufacturers to make progress in this field, and it is also difficult for them to make breakthroughs in the production process, which requires the national investment in scientific research fund to further expand the scope of lithium chemistry research.
