13200 3,7V wiederaufladbare Li-Ionen-Batterie

Rechargeable Li-ion Battery Cell Structure Overview

Engineers design the rechargeable Li-ion battery described in the 13200 3.7V lithium capacitor-style format by integrating a compact electrode stack into a sealed cylindrical enclosure. First, they arrange cathode and anode foils with a microporous separator in between, and they wind the layered structure into a tightly controlled spiral core. Meanwhile, they insert the rolled assembly into a rigid metal housing, and they stabilize internal alignment before electrolyte processing begins. After that, technicians secure the internal structure to prevent displacement during subsequent sealing operations.

Materialsystem und elektrochemische Komponenten

Manufacturers coat lithium metal oxide compounds onto aluminum foil to form the cathode layer, and they apply graphite-based slurry onto copper foil to construct the anode layer. In addition, they introduce a PE/PP multilayer separator to maintain ionic conduction while preventing direct electrode contact. Furthermore, they prepare an organic carbonate electrolyte containing lithium salts such as LiPF6, and they regulate moisture content to maintain chemical stability. Meanwhile, the cylindrical shell uses aluminum alloy or steel material to provide mechanical rigidity and pressure resistance.

Electrode Assembly and Winding Process

Technicians cut coated electrodes into precise strips, and they feed them into automated winding machines to form a uniform jelly-roll structure. Then, they control winding tension carefully to avoid deformation and internal stress accumulation. After that, they insert the rolled core into the cylindrical casing and connect electrode tabs to the terminal structure. Subsequently, they perform laser or resistance welding to secure electrical connections. Meanwhile, they verify positional accuracy to ensure uniform layering throughout the cell.

Formationscyclus und Kontrolle von Industrienormen

Engineers initiate formation cycling to activate electrochemical reactions and stabilize the solid electrolyte interphase layer within the cell. Then, they conduct aging tests under controlled temperature environments 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, and they validate mechanical integrity, electrical consistency, and transport safety requirements for rechargeable Li-ion battery manufacturing.
