304050 얇은 리튬 폴리머 배터리

Thin Lithium Polymer Battery Structural Overview

Engineers construct the 304050 thin lithium polymer battery using an ultra-flat pouch cell architecture. First, they arrange the electrode layers in a stacked structure, including cathode foil, separator film, and anode foil. Then, they laminate these layers into a tightly controlled sheet format to achieve a slim geometric profile. Meanwhile, technicians carefully align each layer to prevent edge offset and internal stress concentration during sealing. After stacking, the cell is transferred into a heat-sealing process to form a flexible pouch structure.

Electrode Material System and Internal Chemistry

Manufacturers build the cathode using lithium metal oxide coating on aluminum foil, while the anode is formed from graphite-based carbon material on copper foil. In addition, a microporous polymer separator is inserted between electrodes to allow lithium-ion movement while preventing direct electrical contact. Furthermore, the electrolyte consists of lithium salt dissolved in organic carbonate solvents, and moisture control is strictly maintained throughout mixing and injection stages. Meanwhile, the aluminum-plastic laminated film serves as the outer shell, providing both sealing and flexibility instead of rigid metal casing.

셀 제조 및 적층 공정

Technicians start by preparing electrode slurries through mixing active materials, conductive agents, and polymer binders into a uniform paste. Subsequently, they coat the slurry onto metal foils using precision coating equipment. After drying, calendaring rollers compress the electrodes to achieve consistent thickness and density. Next, the electrodes are slit into narrow strips and stacked in a layered sequence. Meanwhile, automated alignment systems ensure consistent stacking order to avoid internal misplacement.

Formation Testing and Safety Standards

Engineers conduct initial charge-discharge cycling to activate electrochemical interfaces and stabilize internal structure. Afterwards, aging tests are performed to evaluate voltage consistency and internal resistance stability over time. Finally, insulation testing, sealing verification, and dimensional inspection are completed. Throughout production, the thin lithium polymer battery complies with IEC 62133 and UN38.3 standards, ensuring structural reliability, electrical safety, and transport compliance.
