Component Specifications

Definition
A housing can or pouch is a critical component in cell housing assemblies, designed to contain and protect electrochemical cells (such as lithium-ion cells) from mechanical damage, moisture, and contaminants. It ensures proper alignment, thermal management, and electrical isolation while maintaining the structural integrity of the battery module. The housing can be rigid (metal or plastic) or flexible (pouch-type), depending on the application requirements, and includes features for venting, terminal connections, and mounting.
Working Principle
The housing can operates by enclosing the electrochemical cell stack, providing a sealed environment to prevent electrolyte leakage and external contamination. It maintains internal pressure, facilitates heat dissipation through conductive materials or thermal interfaces, and supports electrical connections via integrated terminals. In pouch designs, the flexible laminate allows for expansion during charge cycles while maintaining a hermetic seal.
Materials
Aluminum alloy (e.g., 3003 or 6061), stainless steel (e.g., 304 or 316), or multi-layer laminated polymer (for pouches, typically PET/AL/PP). Surface treatments may include anodizing, plating, or coating for corrosion resistance and insulation.
Technical Parameters
  • Dimensions Customizable per cell size (e.g., 18650, 21700, pouch dimensions)
  • Sealing Method Laser welding, crimping, or heat sealing
  • Wall Thickness 0.2-1.5 mm (metal) or 0.1-0.3 mm (pouch laminate)
  • Pressure Rating Up to 1.5 bar (for venting safety)
  • Electrical Insulation Dielectric strength > 1000 V
  • Operating Temperature -40°C to 85°C
Standards
ISO 12405-4, IEC 62660-2, UL 1642, DIN EN 62133

Frequently Asked Questions

What is the difference between a housing can and a pouch?

A housing can is a rigid metal or plastic enclosure offering high mechanical strength and thermal conductivity, while a pouch is a flexible laminated polymer bag that allows for lightweight, compact designs and accommodates cell expansion.

How do you ensure sealing integrity in housing cans?

Sealing integrity is achieved through precision welding (e.g., laser or resistance welding), gaskets, or crimping, followed by leak testing (e.g., helium mass spectrometry) to meet industry standards for hermeticity.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
