17350 3.85V 원통형 LiPo 배터리 1200mAh

Cylindrical LiPo Battery 1200mAh Structural Overview

Engineers develop the cylindrical LiPo battery 17350 (3.7V, 1200mAh class) using a compact spiral-wound electrochemical architecture. First, they align cathode-coated aluminum foil, graphite-coated copper foil, and polymer separator layers into a continuous laminated strip. Then, they wind the multilayer structure into a dense cylindrical jelly-roll core under tightly controlled tension. Meanwhile, technicians continuously regulate winding speed and edge alignment to prevent internal layer offset and mechanical stress accumulation. After forming the core, they insert it into a precision metal casing and stabilize its internal geometry before electrolyte injection begins.

Electrochemical Material System

Manufacturers prepare the cathode by coating lithium transition-metal oxide slurry onto aluminum foil current collectors. In parallel, they construct the anode using graphite-based carbon slurry applied onto copper foil substrates. Additionally, they introduce a PP/PE microporous separator to ensure ionic transport while maintaining electrical isolation between electrodes. Furthermore, they formulate an organic carbonate electrolyte containing lithium hexafluorophosphate (LiPF6), and they strictly control moisture content to prevent degradation reactions. Meanwhile, the cylindrical housing uses high-strength steel or aluminum alloy materials to maintain structural integrity under sealed conditions.

Electrode Fabrication and Layer Processing

Technicians begin by dispersing active materials, conductive carbon, and polymer binders into a uniform slurry system. Subsequently, they apply the slurry onto metal foils using precision coating machines with controlled thickness parameters. After that, they dry the coated electrodes through staged thermal ovens to remove residual solvents. Next, calendaring rollers compress the electrode layers to achieve consistent density and surface smoothness. Then, they cut the processed foils into narrow strips and feed them into automated winding equipment to form a tightly packed spiral structure. At the same time, they weld electrode tabs using ultrasonic or resistance techniques to ensure stable current pathways.

형성 사이클링 및 품질 기준 관리

Engineers initiate formation cycling to activate electrochemical interfaces and stabilize the solid electrolyte interphase layer within the cell. Then, they conduct aging tests under controlled temperature conditions to evaluate voltage consistency and impedance behavior. Finally, quality teams perform dimensional inspection, internal resistance measurement, and sealing verification. Throughout manufacturing, compliance is maintained with IEC 62133 and UN38.3 standards, ensuring structural reliability, electrical stability, and transport safety conformity for cylindrical LiPo battery 1200mAh production.
