13400 3.7V Compact Cylindrical Lithium Battery

Compact Cylindrical Lithium Battery Internal Structure

Engineers manufacture the compact cylindrical lithium battery by integrating layered electrode materials into a sealed miniature cylindrical enclosure. Initially, they arrange cathode sheets, separator membranes, and anode layers into a continuous strip configuration, and they roll the structure into a dense cylindrical core. Meanwhile, technicians regulate winding alignment carefully to maintain balanced internal spacing. Afterwards, they position the completed core inside a metal casing and stabilize the structure before electrolyte processing and terminal assembly operations begin.

Raw Material System and Layer Configuration

Manufacturers produce the cathode layer by applying lithium transition-metal compounds onto aluminum current collectors, whereas they create the anode layer using carbon-based graphite slurry coated onto copper foil. In addition, they install a microporous polymer separator composed of polyethylene and polypropylene to maintain ionic movement while blocking electrical contact between electrodes. Furthermore, they formulate the electrolyte with lithium salt dissolved in carbonate solvents, and they monitor purity levels throughout preparation. Meanwhile, the cylindrical shell uses corrosion-resistant alloy materials to maintain enclosure strength and dimensional accuracy.

Electrode Processing and Mechanical Assembly

Technicians prepare electrode slurry through controlled mixing of active powders, conductive agents, and polymer binders. Then, they transfer the slurry onto foil substrates using precision coating equipment. Subsequently, they dry the coated materials in temperature-controlled chambers and compress the electrode surfaces through rolling calibration. After cutting the electrodes into narrow strips, they wind the layers into a spiral core and connect conductive tabs through ultrasonic welding technology. At the same time, operators verify alignment tolerances to avoid uneven pressure inside the cylindrical structure.

Formation Cycling and Manufacturing Standards

Engineers perform controlled formation charging and discharging cycles to stabilize electrochemical interface layers within the cell. Afterwards, they conduct thermal aging procedures under monitored environmental conditions to evaluate impedance and voltage consistency. Finally, quality control teams complete dimensional inspection, insulation resistance analysis, and sealing verification before product release. Throughout production, manufacturers comply with IEC 62133 and UN38.3 standards, ensuring the compact cylindrical lithium battery satisfies international structural, electrical, and transport safety requirements.
