Manufacturing method of lithium battery

  Since lithium-ion rechargeable batteries were officially put into practical use in the early 1990s, in less than 20 years, the capacity has increased rapidly and the market has grown rapidly. Now it is expanding from the use of portable products to the fields of electric vehicles and environmentally friendly power storage. The various technical aspects of the battery still need to be improved, and the development of the battery management system is still a weak link. With the use of batteries in electric vehicles and other fields, people have higher and higher requirements for battery capacity. The larger the battery capacity, the greater the energy that can be released intensively, so the risk is higher. Therefore, the greater the energy density, the more important safety measures are. Standards must also be met in terms of safety, an important and indispensable element. When increasing energy capacity, the development of corresponding safety measures is crucial.

 When a lithium-ion battery is used as a power battery, for example, when it is used as a driving battery of an electric bicycle, it is often necessary to connect 7-13 lithium-ion batteries in series to achieve the voltage required by the motor. As the performance indicators of each cell of the lithium ion battery cannot be completely consistent, due to the differences in the capacity and self-discharge between the cells during use, it accumulates day by day. After a period of use, the charge retention capacity of the battery pack is obvious The reduction affects the promotion and application of lithium-ion batteries in a wider range. Therefore, when multiple batteries are used in series, the performance depends not only on the quality of the battery cells, but more importantly, on the overall quality.

  To solve the above problems, Mikrouna provides an automated production line for lithium-ion batteries. Equipment high precision, high efficiency, serialization and high automation production lines will become the general direction of the industry's development. Fully automated and intelligent lithium battery production equipment will ensure the production process of lithium batteries, so that the produced lithium batteries have better consistency, high reliable safety performance and straight-through yield, thereby reducing production costs.
