Bateria LiPo 16400 3,7V em Formato de Capacitor

Capacitor-Shaped LiPo Battery Structural Configuration

Engineers develop the capacitor-shaped LiPo battery (16400, 3.7V specification) through a compact cylindrical design that integrates layered electrochemical films into a tightly packed roll core. First, they arrange cathode-coated aluminum foil, anode-coated copper foil, and polymer separator sheets into a continuous laminated strip. Next, they wind the multilayer structure into a controlled spiral form while actively regulating tension and alignment to avoid edge displacement. After forming the core, technicians place it into a rigid cylindrical metal enclosure and perform dimensional stabilization prior to electrolyte introduction.

Electrochemical Materials and Layer Engineering

Producers fabricate the cathode by depositing lithium transition-metal compounds onto aluminum current collectors, and they construct the anode using carbon-based graphite slurry coated on copper foil. Meanwhile, they integrate a microporous PP/PE separator to support ion migration while blocking electronic contact between electrodes. In parallel, they prepare a lithium salt electrolyte system using carbonate solvents, carefully managing impurity levels and moisture exposure during formulation. Additionally, the outer casing employs high-strength alloy materials to maintain enclosure stability under internal chemical activity.

Electrode Processing and Spiral Assembly

Technicians initiate electrode production by mixing active powders, conductive agents, and binders into a stable slurry mixture. Subsequently, they apply the slurry onto metal foils through precision coating lines and execute staged drying to remove volatile residues. After that, calendaring equipment compresses the coated layers to achieve controlled density and thickness uniformity. Then, they slit the electrodes into narrow strips and guide them into automated winding systems. During this stage, operators weld electrode tabs using ultrasonic or resistance methods while continuously monitoring alignment accuracy.

Formation Conditioning and Manufacturing Standards

Engineers execute controlled formation cycling to activate electrochemical interfaces and stabilize internal film layers. Subsequently, aging procedures are conducted under regulated temperature environments to observe voltage drift and impedance variation. Finally, quality control teams complete dimensional verification, insulation resistance testing, and structural sealing checks. Throughout production, compliance is maintained with IEC 62133 and UN38.3 requirements, ensuring standardized structural control, electrical consistency, and transport safety validation for capacitor-shaped LiPo battery manufacturing.
