13350 3.7V Lithium Capacitor Battery

3.7V Lithium Capacitor Battery Structure Overview

Engineers design the 3.7V lithium capacitor battery (13350 series) using a hybrid cylindrical architecture that combines lithium-ion electrode chemistry with capacitor-style internal regulation behavior. First, they arrange cathode and anode foils with a high-precision separator layer, and they wind the layered structure into a compact spiral core. Meanwhile, technicians insert the rolled element into a rigid cylindrical metal casing, and they stabilize internal alignment before electrolyte injection begins. After that, they secure the core structure to maintain uniform pressure distribution during subsequent sealing stages.

Material Composition and Electrochemical System

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 that supports ion migration while preventing direct electrode contact. Furthermore, they prepare a lithium salt electrolyte (commonly LiPF6 in organic carbonate solvents), and they strictly control moisture content to maintain chemical stability. Meanwhile, the cylindrical housing uses aluminum alloy or steel material to ensure mechanical rigidity and sealing integrity under internal pressure conditions.

Procédé d’enroulement et d’assemblage d’électrodes

Technicians cut electrode sheets into precise strips, and they feed them into automated winding equipment to form a uniform jelly-roll core. Then, they regulate winding tension carefully to avoid misalignment and internal stress accumulation. After that, they insert the rolled core into the cylindrical shell and connect the electrode tabs to terminal interfaces. Subsequently, they apply laser welding or resistance welding to secure electrical joints. Meanwhile, they verify dimensional consistency to ensure stable internal layering throughout the structure.

Formation Cycling and Industrial Standard Compliance

Engineers initiate formation cycling to activate electrochemical reactions and stabilize the solid electrolyte interphase layer inside the cell. Then, they conduct aging tests under controlled temperature conditions to evaluate voltage stability and impedance behavior. Finally, quality teams perform dimensional inspection, internal resistance measurement, and sealing verification. Throughout production, they comply with IEC 62133 and UN38.3 standards, ensuring structural integrity, electrical consistency, and transport safety compliance for 3.7V lithium capacitor battery manufacturing.
