400 Pieces of Self-Adhesive Solid/Hollow 18650 Battery Insulation Pads, 18650 Battery Insulation Rings, 18650 High-Density Paper, Insulation Pad Circles, Single-Sided Adhesive Batteries

Purpose and function

Highland barley paper is used as a gasket between the battery's positive (or negative) terminal and the metal casing to prevent short circuits caused by electrode-to-shell contact.It is especially suitable for cylindrical batteries such as 18650 and 21700, ensuring a precise fit with the battery structure.Fire and thermal runaway protection

2. prevents fire spread in the event of battery overcharging, overheating, or internal short circuits, buying you valuable time for safe evacuation.Mechanical buffering and shockproofing

3 in high-vibration scenarios such as electric tools and electric vehicles, the flexibility of highland barley paper can absorb mechanical impact, reduce friction between battery cells, and prevent internal short circuits caused by membrane wear.Auxiliary heat dissipation and aging resistance

4. the natural fiber structure has micro-breathability, which helps the battery to dissipate heat evenly; it is also resistant to grease and aging, and is not easily brittle after long-term use, extending the life of the battery pack.
