"A well-designed battery pack is like a precision puzzle – every component must fit perfectly." – Energy Storage Engineer, Tesla Alumni

Case Study: Thermal Runaway Prevention

After implementing advanced packaging techniques, a Shenzhen-based manufacturer reduced thermal incidents by 73% in their 21700-cell power banks.

5 Proven Packaging Strategies

1. Material Selection Matrix

Choose materials based on application requirements:

Application	Recommended Material	Thermal Conductivity
EV Batteries	Aluminum Alloy	120-180 W/m·K
Solar Storage	Fire-retardant PC	0.2-0.3 W/m·K

2. Thermal Management Design

• Implement honeycomb cooling structures
• Use phase-change materials (PCMs) between cells
• Maintain 2-3mm spacing for air circulation

3. Vibration Resistance

Automotive battery packs require:

• Shock-absorbing silicone pads
• Triple-layer compression brackets
• ISO 16750-3 compliance testing
