Produt overview
This specialized cylindrical lithium battery swelling tape is engineered to meet the critical demands of modern battery cell assembly. Designed for cylindrical battery configurations, this tape provides exceptional performance in securing cell windings while optimizing the fit between the cell and its casing. With its unique swelling properties, it ensures enhanced structural integrity and vibration resistance in final battery assemblies.
Key Features
1.High Swell Ratio: Formulated with a specially engineered adhesive layer that expands upon electrolyte contact, effectively filling micro-gaps between the battery cell and the metal casing for a tighter, more secure fit.
2.Excellent Solubility Resistance: Maintains structural integrity and adhesive strength even when exposed to aggressive electrolyte solutions, preventing delamination or failure during battery operation.
3.130℃ Long-Term Heat Resistance: Engineered to withstand continuous exposure to elevated temperatures up to 130℃ without degradation, ensuring reliable performance under demanding operating conditions.
4.Optimized for Cylindrical Cells: Specifically designed to conform to the curved surfaces of cylindrical batteries, providing uniform coverage and consistent holding power.
Primary Applications
1. Cylindrical Battery Cell Winding: Ideal for wrapping and securing the electrode windings (jelly roll) and other cylindrical cell formats.
2. Gap Filling & Cell Fixing: Swells to fill the annular space between the cell winding and the inner wall of the battery casing, eliminating movement and improving thermal transfer.
3. Vibration Dampening: Provides mechanical cushioning that protects internal cell components from shock and vibration damage in electric vehicle and power tool applications.
