13300 3.85V 원통형 리튬 폴리머 배터리

Cylindrical Lithium Polymer Battery Structure Overview

Engineers construct the cylindrical lithium polymer battery (13300, 3.7V class) using a tightly controlled rolled electrode architecture. First, they align cathode, anode, and separator sheets into a continuous laminate stack, and they wind the structure into a compact spiral core. Meanwhile, they insert the wound element into a precision metal casing and stabilize its internal geometry before sealing preparation begins. After that, technicians secure electrode positioning to maintain uniform layer pressure throughout the cell.

Material System and Electrochemical Components

Manufacturers coat lithium metal oxide active materials onto aluminum foil to form the cathode layer, and they apply graphite-based slurry onto copper foil to build the anode structure. In addition, they introduce a PP/PE multilayer separator to maintain ionic transport while preventing internal contact between electrodes. Furthermore, they prepare an organic carbonate electrolyte containing lithium hexafluorophosphate, and they strictly control moisture content to avoid chemical instability. Meanwhile, the cylindrical shell uses high-strength steel or aluminum alloy to ensure structural rigidity during processing.

전극 권선 및 조립 공정

Technicians cut electrode sheets into precise strips and feed them into automated winding equipment. Then, they control winding tension and alignment carefully to prevent deformation and uneven layering. After that, they insert the rolled core into the cylindrical housing and connect the bottom terminal through conductive bonding. Subsequently, they install the top cap assembly and apply laser or resistance welding to complete the electrical interface. Meanwhile, they verify dimensional consistency to ensure stable internal compression.

Formation Cycling and Standard Compliance Control

Engineers initiate formation cycling to activate electrochemical reactions and stabilize the solid electrolyte interphase layer inside the cell. Then, they conduct aging tests under regulated temperature conditions 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, ensuring structural integrity, electrical consistency, and transport safety compliance for cylindrical lithium polymer battery manufacturing.
