1, Purpose and advantages:
Conductive carbon coated copper foil can replace traditional aluminum foil as the negative electrode substrate, with better performance.
Better conductivity and lower internal resistance
Better mechanical strength and toughness, avoiding short circuits caused by dendritic growth
Better electrode material coating strength
Therefore, it will provide greater discharge capacity and longer service life for lithium-ion batteries
2. Conductive carbon coating:
Double side coating with a thickness of 1 micron on each side
Density: 0.54 g/square meter
Surface resistivity:<30 ohms/25um ^ 2
3. Copper substrate:
Purity>99.9%
Thickness: 9 microns
