201/301/304 Stainless Steel Strips – Sturdy Belt for Lithium Battery Pack Assembly
When assembling lithium battery packs—especially prismatic lithium battery modules for energy storage systems—sturdiness, corrosion resistance, and precise fit are non-negotiable. Our stainless steel strips (steel belts) solve the pain points of flimsy or rust-prone alternatives: available in 201, 301, and 304 grades, they deliver reliable structural support to keep battery modules tightly secured, while withstanding long-term use in indoor/outdoor energy storage environments. Whether you’re building small portable battery packs or large-scale energy storage modules, these steel strips are the durable, cost-effective choice for consistent assembly quality.
1. Core Advantages: Why Choose Our Stainless Steel Strips?
| Advantage |
Key Benefit for Battery Pack Manufacturers |
| Multi-Grade Material Options |
201 (cost-effective), 301 (high elasticity), 304 (superior corrosion resistance) – match different budget & environmental needs. |
| Sturdy Structural Support |
High tensile strength (≥500MPa for 304 grade) keeps prismatic lithium battery modules tightly fixed, preventing loosening during transport/use. |
| Corrosion & Rust Resistance |
304 grade offers excellent resistance to moisture, humidity, and mild chemicals – ideal for outdoor energy storage or high-humidity workshops. |
| Precise Customization |
Cut-to-size widths/thicknesses and optional surface treatments (polished/galvanized) ensure a perfect fit for your battery pack design. |
| Easy to Assemble |
Smooth edge processing avoids damaging battery casings; compatible with common assembly tools (e.g., spot welders, bolts) for efficient production. |
