Custom Industrial Lithium Polymer (LiPo Pouch Cell) Solutions (0.5mm Ultra-Thin to 100Ah Large Format)
GEB is a premier manufacturer of custom-engineered Lithium Polymer (LiPo / Pouch) battery cells and multi-cell assemblies. Utilizing flexible aluminum-plastic laminated packaging, our pouch batteries eliminate rigid metal cans to provide superior volumetric energy densities up to 580 Wh/L and gravimetric densities up to 280 Wh/kg. Ranging from ultra-thin smart card cells (as slim as 0.5 mm thickness) to high-capacity industrial pouch cells exceeding 53 Ah per single cell, GEB powers next-generation IoT hardware, medical devices, and industrial electronics.
With over 3,000 existing pouch cell tooling dimensions, low tooling fees for custom shapes (curved, round, polygonal), and rapid prototyping turnaround within 15–20 days, GEB solves geometric constraints for electronic design engineers worldwide.

Need a Custom Pouch Dimension or Special Tab Orientation?
The matrix above highlights our most active mass-production LiPo tooling dimensions. With over 3,000+ custom mold tools available at GEB, we can adjust thickness in 0.1mm increments, customize tab width/polar spacing, add built-in NTC thermistors, and integrate client-specified wire harnesses (JST, Molex, Hirose) with rapid 15–20 day prototype delivery.
Electrode Stacking Precision, Gas Expansion Control & Pouch Packaging
Unlike rigid cylindrical cells, pouch cells rely on external encapsulation barrier integrity. GEB eliminates swelling and gas generation risks through advanced chemical processing:
- Low-Moisture Cleanroom Stacking: Automated lamination executed under strict <1% relative humidity (dew point < -45°C), preventing electrolyte hydrolysis and HF acid generation.
- Secondary Vacuum Degassing SOP: After pre-formation cycles, gas bubbles are evacuated under high vacuum and hermetically heat-sealed along dedicated gas pockets.
- Four-Layer Composite Barrier Film: Aluminum foil coated with modified polypropylene (CPP) and nylon layers providing zero moisture permeability and high electrolyte solvent resistance.
- Precision PCM Protection Circuit: Micro-PCBs with dual MOSFET switches protecting against over-charge (4.28V cut-off), over-discharge (2.80V cut-off), and short circuits.
OEM / ODM Bespoke Pouch Cell Engineering
GEB offers industry-leading dimensional flexibility for custom hardware enclosures:
- Custom Dimensional Envelope: Thickness from 0.5mm to 16mm, width from 8mm to 180mm, and length from 15mm to 350mm.
- Shaped Cells: Curved batteries for smart wristbands, round cells for smartwatches, trapezoidal cells for VR head-mounted displays, and C-shaped cells.
- Terminal & Wiring Options: Bare solder tabs, nickel wire leads, flexible printed circuits (FPC), JST (SH, PH, ZH), Molex PicoBlade, and Hirose connectors.
- High-Temperature & Wide-Temp Chemistries: Specialized electrolyte packages operational from -40°C to +80°C for automotive tracking telematics.
