Key Features
Tight Thickness Control
±0.2mm dimensional control ensures stable fitting in molded enclosures and reduces assembly variation.
Cobalt Based Cell Chemistry
Cobalt based cathode system maintains stable discharge curve and retains over 80% capacity after 500 cycles.
Low Resistance Welding
Ultrasonic tab welding reduces contact resistance and limits heat generation during continuous operation.
Swelling Control Structure
Aluminum plastic pouch with controlled sealing process reduces gas accumulation during normal charge cycles.

FAQ
Q: Does the battery include protection circuitry?
A: Optional PCM/PCB integration is available to protect against electrical abuse. We can customize the protection parameters based on your device's load.
Q: What quality inspections are performed?
A: Every cell undergoes 100% OCV (Open Circuit Voltage), internal resistance testing, capacity grading, and a 24-hour aging test before shipment.
Q: Can we request samples for prototyping?
A: Yes. Performance samples are available for dimensional verification and compatibility testing prior to mass production.
Q: What are the shipping logistics for hazardous materials?
A: We use certified DG (Dangerous Goods) channels for air and sea freight, ensuring all lithium battery transport regulations are strictly met.
