Aluminum Foil Current Collector for Li-ion/Li-S/Na-ion Button
Batteries – Cathode Current Collector for Lithium Battery
Product Overview
One-Stop Supplier of Experimental Consumables
We provide high-conductivity, high-temperature-resistant, and corrosion-resistant aluminum foil of premium quality. Our products feature finely polished surfaces—smooth with no burrs. We offer services including width slitting, retail by the meter, and precision cutting, ensuring minimal tolerance.
Product Description
- Packaging Material: Carton packaging
- Storage Conditions: Store at room temperature in a sealed condition
- Storage Period: 3 months from the production date
- Hazard Class: 4 Dangerous Goods Classification and Operational Specifications
- Packaging Category: III Packaging Category Classification
- Lithium-ion battery, cell, power battery, aluminum foil for lining.
- Aluminum foil weight tolerance: +/- 5%. When using specifically, it is recommended that teachers test the specific weight of the empty foil material at the same time to facilitate the accurate deduction of the weight of the foil material corresponding to the research pole piece of the coating.
