How to Connect Pouch Cells in Series / Parallel
The tabs of pouch cells serve as conductive output terminals. The mainstream connection processes are as follows:
Laser Welding: Mainly applied in fully automatic production lines with fast welding speed and excellent consistency. (Recommendation)
Ultrasonic Welding: Weld tabs with nickel strips, copper busbars or PCBs. This is the widely adopted industrial solution featuring low contact impedance and reliable connections. (Recommendation)
Bolt/Screw Connection: Suitable for large-size thick tabs. It allows easy disassembly and maintenance yet requires more assembly space. (If must）
2. Why NMC Pouch Cell?
Ultra-High Energy Density & Lightweight Design
Replacing bulky metal casings with lightweight aluminum-laminated packages, NMC pouch cells deliver a high gravimetric energy densityand excellent volumetric energy density. This ultra-light, high-energy structure effectively extends EV driving range and optimizes the portability of portable electronic devices.
Excellent Thermal Performance & High-Rate Fast Charging
The thin stacked structure enables full-surface heat dissipation, effectively eliminating cell hot spots when cooperating with liquid cooling systems. It stabilizes NMC cathode structure during high-current charging, supporting high C-rate fast charging while maintaining reliable safety and long cycle life.
Flexible Form Factor & High Space Utilization
Featuring highly customizable shapes and sizes, pouch cells adapt to diverse installation spaces and perfectly match EV skateboard chassis designs. They achieve over 90% pack volumetric utilization, vastly outperforming 60–70% efficiency of conventional cylindrical cells for superior space utilization.
Low DCIR & Lifelong Stable Power Output
Multi-tab and full-tab designs lower DC internal resistance and electrochemical polarization, providing a flat and stable discharge voltage plateau. Reduced Joule heat inhibits cathode degradation and metal dissolution, sustaining stable power output and structural stability throughout the full cell lifecycle.

4. Customer FAQ
Q: How to extend the cycle life of NMC pouch cells?
A: Limit charging to 90% SOC (around 4.05V) instead of full 4.2V charge to boost cycle life by 40%. Operate within 20%–80% SOC and avoid deep discharge or full charge frequently. 25℃ is the optimal operating temperature; long-term temperature above 35℃ accelerates side reactions and cuts lifespan by nearly 40%. For battery packs, match cells with capacity difference within 1% and adopt active balancing BMS to stabilize voltage consistency.
Q: What chemistries of lithium cells do you supply?
A: We supply NCM ternary lithium cells and LFP lithium iron phosphate cells in multiple shapes (prismatic/Pouch/cylindrical etc) for different application scenarios. And Strict grouping on voltage, internal resistance & capacity ensures low difference for parallel/series assembled battery packs before dellivery.
Q: What certificates do you provide for export ？
A: Nogibattery can offer full transport documents including MSDS, UN38.3, transport safety report etc.We also provide global certifications like IEC, RoHS, REACH, UL and regional certificates as required. Supporting files for EU Battery Regulation are available on request.
Q: Can you ship to our port/warehouse directly?
A: Yes. We offer flexible shipping terms of FOB, CIF, DAP and DDP for global lithium battery delivery. DDP door-to-door tax-inclusive shipping is widely favored by our overseas buyers.
