Compact Cylindrical Lithium Battery Structural Overview
Engineers construct the compact cylindrical lithium battery (13450 series, 3.7V class) using a tightly controlled micro roll-core architecture. First, they laminate cathode foil, anode foil, and separator film into a continuous layered strip, and they wind it into a compact spiral core under controlled tension. Meanwhile, they regulate alignment precision to keep electrode spacing uniform throughout the winding process. After that, technicians insert the finished core into a compact cylindrical metal casing and stabilize its internal geometry before electrolyte filling begins.
Material Composition and Electrochemical Layers
Manufacturers coat lithium transition-metal oxide onto aluminum foil to form the cathode layer, while they apply graphite-based slurry onto copper foil to build the anode layer. In addition, they introduce a PP/PE microporous separator to support lithium-ion transport and prevent internal short contact. Furthermore, they prepare an organic carbonate electrolyte containing lithium salts such as LiPF6, and they strictly control moisture levels to maintain chemical stability. Meanwhile, the cylindrical shell uses high-strength steel or aluminum alloy to ensure structural rigidity and sealing performance.
전극 제작 및 권선 공정
Technicians mix active materials, conductive carbon, and polymer binders into a uniform slurry system, and they coat it onto metal foils using precision coating equipment. Then, they dry the coated electrodes through staged thermal processing to remove residual solvents. Subsequently, they compress electrode surfaces through calendaring to regulate density and thickness consistency. After cutting the electrodes into narrow strips, they feed them into automated winding machines to form a uniform jelly-roll core. Meanwhile, they weld electrode tabs using ultrasonic or resistance methods to ensure stable electrical connections.
Formation Cycling and Standard Compliance System
Engineers initiate formation cycling to activate electrochemical reactions and stabilize internal interfacial layers. Then, they conduct aging tests under controlled temperature environments to evaluate voltage stability and impedance behavior. Finally, quality teams perform dimensional inspection, insulation resistance testing, and sealing verification. Throughout production, manufacturers comply with IEC 62133 and UN38.3 standards, ensuring structural integrity, electrical consistency, and transport safety compliance for compact cylindrical lithium battery manufacturing.
