Custom Pouch-Cell Tab Lead Manufacturing
Custom development and contract production of tab leads (cell terminals) for laminate-type lithium-ion pouch cells, with in-house sealant film lamination technology ensuring electrolyte leakage prevention and long-term seal integrity.

Problem solved
Pouch cell tab leads must provide a hermetically sealed electrical feedthrough between the cell interior (organic electrolyte) and external circuit, while withstanding the cell assembly heat-seal process and long-term exposure to electrolyte. Improper tab lead design causes electrolyte leakage, cell degradation, and fire risk. Standard off-the-shelf tab leads do not accommodate the wide variety of cell capacities, form factors, and current ratings required by custom pouch cell projects.
Application contexts
- custom pouch cell prototype and production runs
- mid-to-small volume Li-ion battery manufacturing
- specialty pouch cells for medical, industrial, and consumer devices
- battery R&D labs requiring flexible tab lead sourcing
Technical principle
A flat-rolled metal conductor (aluminum for cathode, nickel-plated copper or nickel for anode) is partially laminated on both sides with a multi-layer polyolefin sealant film. The sealant film fuses with the aluminum laminate pouch film during the cell heat-seal process, creating an electrolyte-tight barrier. Key parameters: conductor cross-section for current rating, sealant film composition for electrolyte resistance, and seal width for mechanical integrity.
Typical use cases
- Prototype pouch cell tab leads for a university or startup battery developer needing 100-500 custom units
- Medical device pouch cell requiring biocompatible sealant materials and tight dimensional tolerances
- Industrial-grade large-format pouch cell requiring high-current nickel-plated copper tab leads
Partnership route
How global engineering teams typically engage this asset.
Helpful to include: Cell capacity and maximum continuous discharge current for conductor cross-section sizing · Pouch film material and thickness for seal compatibility · Desired tab lead length, width, and sealant area dimensions · Annual volume estimate (prototype, pre-production, or mass-production) · Any environmental or regulatory requirements (RoHS, REACH, medical-grade)
