Reasons for leakage of lithium-ion batteries. With the further expansion of the electric vehicle market and the continuous improvement of driving range requirements, automobile manufacturers have put forward higher requirements for power lithium batteries in terms of energy density, manufacturing costs, cycle life, and additional product attributes. Without significant breakthroughs in the field of raw materials, adding cylindrical lithium-ion batteries to obtain larger battery capacity has become a direction of exploration. Today, the small series of cylindrical lithium-ion battery technology and the reasons for the leakage.

Production process of cylindrical lithium-ion batteries

Objectively speaking, the production process of lithium-ion batteries is divided into three parts: the production of electrode plates, the production of battery cells, and the assembly of batteries. In the production process of lithium-ion batteries, the production of electrode plates is the foundation, and the production of batteries is the core. The assembly of batteries is related to the quality of lithium-ion battery products. The specific processes for the production of lithium-ion batteries include positive and negative pulping, positive and negative plates, steel shell assembly, liquid injection, testing, and packaging.

As is well known, the production process of lithium-ion batteries is very complex. After all, the safety performance of lithium-ion battery products is directly related to the life and health of consumers. In the production and manufacturing of natural lithium-ion batteries, there are high requirements for equipment performance, accuracy, stability, and automation.
