18650-1P2S 7.4V 2600mAh 탈착식 배터리

2600mAh Battery Pack Lithium Ion Structural Overview

Engineers assemble the 2600mAh Removable Batteries (18650-based 1P2S configuration) using a controlled series-connected architecture. First, they select two matched 18650 cylindrical cells with aligned capacity, voltage curve, and internal resistance characteristics. Then, they arrange the cells into a fixed 1P2S electrical structure, ensuring consistent polarity orientation and mechanical spacing. Meanwhile, technicians place the cells into an insulating holder that stabilizes geometry and limits vibration-induced displacement during assembly. After positioning, they prepare the module for interconnection and protective circuit integration.

Cell Chemistry and Internal Material Composition

Manufacturers construct each lithium-ion cell using a layered electrochemical system composed of a lithium metal oxide cathode and a graphite-based anode. In addition, they insert a microporous polymer separator between electrode layers to maintain ionic transport while preventing internal short circuits. Furthermore, they fill the cell with organic carbonate electrolyte containing lithium salts, and they strictly control moisture levels during processing to avoid chemical degradation. Meanwhile, each 18650 cylindrical shell uses nickel-plated steel casing to maintain structural sealing and pressure stability throughout operation.

Electrode Processing and Cell Fabrication Flow

Technicians begin electrode production by mixing active materials, conductive carbon, and polymer binders into a uniform slurry. Subsequently, they coat the slurry onto aluminum and copper foil collectors using precision coating systems. After coating, they dry the electrodes under controlled temperature conditions to remove solvents. Next, calendaring rollers compress the electrode layers to achieve consistent density and thickness. Then, they slit the processed sheets into strips and wind them into spiral jelly-roll structures inside automated winding equipment. Meanwhile, operators weld electrode tabs using ultrasonic or resistance welding to ensure stable current conduction paths.

편대 순환 및 표준 준수 통제

Operators perform controlled formation cycling to activate electrochemical interfaces and stabilize internal SEI layers. Next, they conduct aging tests under regulated temperature environments to evaluate voltage consistency and impedance stability. Finally, quality inspection teams complete electrical verification, insulation resistance testing, and structural checks. Throughout manufacturing, the 2600mAh lithium ion battery pack is validated under IEC 62133 and UN38.3 requirements, ensuring compliance with transport safety and electrical reliability standards.
