13300 3.7V Capacitor-Shaped Lithium Battery

Capacitor-Shaped Lithium Battery Structure Overview

Engineers construct the capacitor-shaped lithium battery using a compact cylindrical architecture that resembles a hybrid form factor. First, they align electrode foils and separator layers into a tightly controlled spiral winding, and they roll the assembly into a dense core structure. Meanwhile, they insert the wound element into a rigid metal shell designed for sealed containment. After that, technicians stabilize internal geometry and prepare the unit for electrolyte infusion under controlled environmental conditions.

재료 조성 및 전기화학 시스템

Manufacturers coat lithium metal oxide compounds onto aluminum foil to form the cathode layer, and they apply graphite-based slurry onto copper foil to build the anode layer. In addition, they introduce a microporous PP/PE separator to maintain ionic pathways while preventing direct electrode contact. Furthermore, they prepare an organic carbonate electrolyte containing lithium salts such as LiPF6, and they control moisture levels to maintain chemical stability. Meanwhile, the outer casing uses aluminum alloy or steel material to provide structural rigidity and sealing reliability.

전극 권선 및 조립 공정

Technicians cut coated electrodes into precise strips, and they feed them into automated winding machines to form a uniform spiral core. Then, they regulate winding tension carefully to avoid deformation and internal stress accumulation. After that, they insert the rolled structure into the cylindrical housing and connect electrode tabs to terminal interfaces. Subsequently, they apply laser or resistance welding to secure electrical contact points. Meanwhile, they verify alignment accuracy to maintain consistent layer distribution.

편대 순환 및 표준 준수 시스템

Engineers initiate formation cycling to activate electrochemical reactions and stabilize the solid electrolyte interphase layer within the cell. Then, they conduct aging tests under regulated temperature environments to evaluate voltage stability and impedance behavior. Finally, quality teams perform dimensional inspection, internal resistance testing, and sealing verification. Throughout production, they comply with IEC 62133 and UN38.3 standards, ensuring structural integrity, electrical consistency, and transport safety compliance for capacitor-shaped lithium battery manufacturing.
