Lithium Battery Carbon Coated Aluminum Foil

Carbon-coated aluminum foil is made of composite slurry mainly composed of conductive carbon and high-purity electronic aluminum foil by transfer coating process.
Application range
Power type lithium battery with fine particle active material
Positive electrode is lithium iron phosphate
Positive electrode is fine particle ternary/lithium manganate
Used in supercapacitors and lithium primary batteries (lithium iron, lithium manganese, lithium iron, button type, etc.) to replace etched aluminum foil
Function
Inhibit battery polarization, reduce thermal effect, and improve rate performance;
Reduce battery internal resistance, and significantly reduce the dynamic internal resistance increase during the cycle process;
Improve consistency and increase battery cycle life;
Improve the adhesion between active material and current collector, and reduce the manufacturing cost of pole piece;
Protect the current collector from being corroded by electrolyte;
Improve the high and low temperature performance of lithium iron phosphate battery, and improve the processing performance of lithium iron phosphate and lithium titanate materials.
Notes
Storage requirements are in an environment with a temperature of 20±5℃ and a humidity of no more than 50%. During transportation, the aluminum foil must be protected from corrosion by air and water vapor;
The D50 of the corresponding coated active material should not be greater than 4~5μm, the compaction density should not be greater than 2.25g/cm, and the specific surface area should be in the range of 13~18㎡/g.
The heat dissipation of the carbon layer is worse than that of the aluminum foil, so the belt speed and baking temperature need to be properly adjusted during coating;
Carbon-coated aluminum foil has a considerable improvement in the comprehensive performance of lithium batteries and capacitors, but it cannot be used as the main factor to change certain aspects of the battery performance, such as battery energy density, high and low temperature performance, high voltage, etc.
