- **Caution**: 

### Q: What materials are commonly used in cell housing assemblies for lithium-ion batteries?
**A**: Cell housing assemblies are typically manufactured from aluminum alloy, stainless steel, or nickel-plated steel to provide structural integrity, corrosion resistance, and electrical conductivity while protecting internal battery components.

### Q: What is the purpose of the safety vent (CID) in a battery cell housing?
**A**: The safety vent, or Current Interrupt Device (CID), is a critical safety feature that activates under excessive internal pressure or temperature, disconnecting the circuit to prevent thermal runaway and potential battery failure.

### Q: How does the cell housing assembly impact battery performance and safety?
**A**: The housing provides mechanical protection for electrodes and electrolytes, maintains structural stability during charge cycles, enables proper thermal management, and incorporates safety mechanisms like terminals and vents to ensure reliable operation in electronic devices.
