501740 3,7V литий-полимерный аккумулятор

501740 Li-Polymer Battery Structural Overview

Engineers construct the 501740 Li-Polymer battery using a compact pouch-cell architecture with tightly controlled dimensional parameters. First, they align the electrode stack according to the 1S lithium polymer configuration and ensure consistent spacing across the flat cell body. Then, technicians apply insulation layers at edge zones to prevent internal contact stress during sealing. Meanwhile, cell components are pre-matched by voltage and internal resistance to reduce imbalance during later electrical assembly. After alignment, the structure proceeds into lamination and pouch enclosure processing. (Typical 501740 format follows ~5×17×40 mm class LiPo pouch structure)

Материалы электродов и внутренний состав

Manufacturers build the cathode using lithium metal oxide coated on aluminum foil, while the anode is formed from graphite-based carbon material coated onto copper foil. In addition, a microporous polymer separator is inserted between electrode layers to allow lithium-ion movement while blocking direct electrical contact. Furthermore, the electrolyte consists of lithium salts dissolved in organic carbonate solvents, and strict moisture control is maintained throughout filling and sealing operations. Meanwhile, the aluminum-plastic composite film forms the external enclosure, replacing rigid metal housing with a flexible sealed pouch structure.

Manufacturing and Layer Processing

Technicians begin by preparing electrode slurry using active materials, conductive additives, and polymer binders, mixing them into a uniform suspension. Next, automated coating equipment applies the slurry onto metal foil substrates with controlled thickness accuracy. After drying, calendaring rollers compress the electrode layers to achieve stable density and uniform electrochemical behavior. Subsequently, the electrodes are cut into precision strips matching the 501740 format and stacked in a layered sequence. Meanwhile, alignment systems continuously verify stacking accuracy before the cell enters final assembly.

Стандарты тестирования формации и соответствия

Engineers conduct initial charge-discharge cycling to activate electrochemical interfaces and stabilize internal reactions. Afterwards, aging tests evaluate voltage consistency and internal resistance drift across time. Finally, sealing integrity tests, electrical verification, and safety inspections are completed. Throughout production, the 501740 Li-Polymer Battery complies with IEC 62133 and UN38.3 transport safety standards, ensuring structural reliability, electrical stability, and shipping compliance.
