Cylindrical Lithium-ion Battery
Safety risks: air and moisture ingress may cause internal chemical reactions leading to swelling, leakage, short circuit, or even fire and explosion.
Performance degradation: micro leaks reduce battery capacity, increase internal resistance, and affect lifespan and charge/discharge performance.
Quality instability: poor sealing leads to lower yield rates, higher repair rates, and affects shipment stability.
Lithium Polymer Battery
Ensures safety: prevents electrolyte leakage and external moisture ingress, avoiding swelling, combustion, and other risks.
Improves quality: ensures stable battery capacity and longer lifespan, reducing after-sales issues.
Process control: verifies sealing processes such as heat sealing and welding to improve yield.
Meets high standards: complies with the strict sealing requirements of high-end applications like drones and medical devices.
Ternary Lithium Battery
Higher fire risk: ternary systems are highly sensitive to moisture and electrolyte; even minor leaks can cause thermal runaway or explosion.
Shortened lifespan: insufficient airtightness leads to electrolyte evaporation and internal corrosion, causing rapid capacity decay.
Process control issues: production fluctuations may cause poor welding and sealing of caps, requiring real-time airtightness monitoring.
