Why Nickel Sheet Thickness Matters in Lithium Battery Packs

When designing lithium battery packs, the nickel sheet thickness plays a pivotal role in balancing conductivity, thermal management, and structural integrity. Think of it as the "goldilocks zone" – too thin, and it risks overheating; too thick, and it adds unnecessary weight. Most manufacturers use nickel strips ranging from 0.1mm to 0.3mm, but the optimal choice depends on application-specific requirements.

Key Factors Influencing Thickness Selection

• Current Load: High-drain EV batteries often use 0.2mm+ sheets
• Thermal Resistance: Thicker sheets (0.25mm) better handle >80°C environments
• Cost Efficiency: 0.15mm sheets reduce material costs by ~18% in consumer electronics

Industry Trends Shaping Nickel Sheet Specifications

The push for higher energy density (now averaging 280-300 Wh/kg in premium EVs) demands precision in material selection. Emerging technologies like solid-state batteries and module-less CTP designs are driving innovations in nickel sheet engineering.

Case Study: Thermal Runway Prevention

A recent project for grid-scale storage systems demonstrated that increasing nickel sheet thickness from 0.15mm to 0.18mm reduced hotspot temperatures by 12°C during 2C continuous discharge cycles.
