LEAD Smart Integrated Manufacturing Solutions for Cylindrical Battery

Aging Process in Cylindrical Lithium-Ion Battery Production
Aging process is a crucial phase in the production of cylindrical lithium-ion batteries, where newly assembled battery cells undergo controlled storage under specific temperature, voltage, and time conditions to stabilize their electrochemical performance before final use. This process ensures the formation of a stable Solid Electrolyte Interphase (SEI) layer, which is essential for preventing electrolyte decomposition and enhancing cycle life. Additionally, aging helps identify defective cells by detecting abnormalities like self-discharge, voltage decay, or internal short circuits, thereby improving overall product reliability. The process typically involves multiple stages, including high-temperature aging to accelerate SEI formation and room-temperature aging to monitor long-term stability. By optimizing aging parameters, manufacturers can enhance the performance, safety, and longevity of cylindrical lithium-ion battery cells, ensuring they meet industry standards for applications in electric vehicles, energy storage, and consumer electronics.
