501040 Batterie 3,7V

501040 3.7V Battery Structural Overview

Engineers construct the 501040 3.7V lithium polymer battery using a compact pouch-cell geometry with a defined dimensional standard. First, they align the electrode stack in a flat layered format, ensuring consistent thickness across the cell body. Then, technicians position the cathode, separator, and anode in a controlled stacking sequence to maintain uniform internal spacing. Meanwhile, insulation films are inserted at boundary zones to reduce mechanical stress during sealing. After stacking, the structure moves into lamination and pouch forming processes. (Model specification reference: 501040 size approx. 5×10×40 mm cylindrical naming standard system)

Matériaux d’électrodes et chimie interne

Manufacturers build the cathode using lithium metal oxide coated on aluminum foil, while the anode uses graphite-based carbon material applied on copper foil. In addition, a microporous polymer separator is placed between electrodes to enable ion transport while preventing direct contact. Furthermore, the electrolyte consists of lithium salts dissolved in organic carbonate solvents, and moisture control is strictly maintained during preparation and filling. Meanwhile, the aluminum-plastic laminated film forms the external enclosure, replacing rigid metal housing with a flexible sealed structure.

Manufacturing Process and Cell Forming

Technicians begin by preparing electrode slurries using active materials, conductive additives, and polymer binders, mixing them into a uniform paste. Next, automated coating equipment applies the slurry onto metal foils with controlled thickness accuracy. After drying, calendaring rollers compress the electrodes to achieve stable density. Subsequently, the electrodes are cut into precise dimensions matching the 501040 form factor and stacked into layered assemblies. Meanwhile, alignment systems continuously verify positioning accuracy before sealing.

Normes d’essais de formation et de conformité

Engineers perform initial charge-discharge cycling to activate electrochemical stability and balance internal interfaces. Afterwards, aging tests evaluate voltage consistency and internal resistance drift over time. Finally, sealing inspection, electrical verification, and safety testing are completed. Throughout production, the 501040 3.7V battery follows IEC safety requirements and UN38.3 transport standards, ensuring structural reliability, electrical stability, and shipping compliance.
