3,7V 906090 LiPo-Batterie

A 3.7V 906090 LiPo battery uses a single lithium polymer pouch-cell structure. Engineers set its nominal voltage at 3.7V and limit the full charge to 4.2V. They maintain low internal resistance to ensure consistent electrical flow. Manufacturers stabilize capacity by precisely matching electrodes and controlling electrolyte composition. Consequently, the battery sustains predictable performance during repeated charge and discharge cycles.

Materials and Electrode Construction

Producers layer lithium cobalt oxide or blended cathode materials with graphite anodes to create the internal structure. Copper and aluminum foils act as current collectors, providing low-resistance pathways. In addition, a microporous polymer separator prevents electrode contact while allowing ions to pass through efficiently. The aluminum-plastic laminated pouch encloses the chemistry, maintaining flexibility and resisting mechanical stress. This approach also protects the battery from punctures or deformation during handling.

Assembly and Electrical Configuration

Technicians first sort cells by voltage and internal impedance to reduce inconsistencies. They use precision spot welding to attach nickel tabs, forming reliable electrical connections while minimizing heat impact. Next, they integrate a protection circuit module to monitor and control overcharge, over-discharge, and over-current events. Lead wires are carefully secured with strain relief to prevent loosening during vibration or movement. These steps ensure the battery operates safely and reliably.

Abdichtung und strukturelle Fertigstellung

Workers seal the pouch through controlled heat-lamination. This locks in the electrolyte and blocks moisture ingress. Then, they apply outer insulation layers to reinforce mechanical strength and maintain the battery’s dimensions. After sealing, technicians perform leak and insulation resistance tests to confirm structural integrity. These inspections guarantee consistent quality across production batches.

Standards and Charging Control

Manufacturers follow international safety and transport standards, including UN38.3, CE, and RoHS compliance. They apply a constant-current/constant-voltage (CC/CV) method to control charging and limit voltage to 4.2V per cell. Finally, engineers conduct cycle tests at controlled temperatures to verify stable discharge behavior. These tests ensure the battery maintains performance over repeated high-rate usage.
