SPIDER Automation | 2-Hole Adhesive Battery Insulation Mat for 18650/18350 Cells | 10 Mats
The SPIDER Automation 2-Hole Adhesive Battery Insulation Mat is a terminal insulation accessory designed for two-cell arrangements using compatible 18650 and 18350 cylindrical battery cells. Its double-hole configuration provides insulation around the terminal regions of two cells during battery pack assembly.
The mat features a thin insulating paper construction with an adhesive backing for peel-and-stick application. It can be positioned on the intended cell surfaces to help separate conductive areas and reduce the possibility of unintended electrical contact. Each sheet contains 10 individual double-hole insulation mats for battery fabrication and maintenance work.
Technical Features & Functional Benefits
- Two-Cell Insulation Layout: The double-hole configuration is designed for battery assemblies involving two cylindrical cells.
- Adhesive Application: The peel-and-stick format supports convenient positioning on compatible battery surfaces.
- Terminal Area Coverage: The ring-shaped openings and surrounding insulating material provide coverage around the intended terminal regions.
- Short-Circuit Risk Reduction: Helps prevent accidental electrical contact between exposed conductive areas when correctly positioned.
- Thin Construction: The 0.25mm profile is suitable for compact battery pack assembly.
- Multi-Mat Sheet: Each sheet contains 10 individual mats for repeated assembly work.
Applications
This adhesive insulation mat is intended for terminal insulation in cylindrical-cell battery assemblies and related battery fabrication work.
- 18650 Battery Pack Assembly: For terminal insulation in suitable two-cell battery arrangements.
- 18350 Battery Pack Assembly: For insulation around terminal areas in compatible two-cell configurations.

Connection & Operating Recommendations
Correct positioning of terminal insulation is important when assembling cylindrical-cell battery packs. Align the two-hole layout with the physical cell arrangement and ensure that the insulating material covers the intended conductive areas without obstructing the required electrical connections.
- Cell Arrangement: Match the double-hole layout to the physical arrangement of the two battery cells before applying the mat.
- Terminal Alignment: Position the insulation openings accurately around the intended terminal areas so that required connection points remain accessible.
- Adhesive Application: Apply the mat to a clean, dry surface and press it evenly to maintain proper placement.
- Welding Compatibility: Keep the required nickel strip or nickel-plated steel connection areas accessible for the intended spot-welding arrangement.
- Additional Insulation: Use suitable cell rings, fish paper or other insulation components wherever the complete battery pack design requires further separation.
- Battery Assembly: Use an appropriate cell arrangement, welding method and protection circuitry for the complete battery pack.
