How to improve the adhesion between battery electrode material and aluminum foil
Carbon coated aluminum foil is a composite slurry mainly composed of conductive carbon and high-purity electronic aluminum foil, made using a transfer coating process. Power type lithium batteries with fine particle active substances
The positive electrode is Iron(II) phosphate lithium
Ternary/lithium manganese oxide with fine particles as the positive electrode
Used for supercapacitors and lithium primary batteries (lithium sub, lithium manganese, lithium iron, button type, etc.) to replace etched aluminum foil to suppress battery polarization, reduce thermal effects, and improve rate performance;
Reduce the internal resistance of the battery and significantly reduce the dynamic internal resistance increase during the cycling process;
Improve consistency and increase battery cycle life;
Improve the adhesion between the active substance and the collector, and reduce the manufacturing cost of the electrode;
Protect the collector from electrolyte corrosion;
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. Storage requirements: In an environment with a temperature of 20 ± 5 ℃ and a humidity of no more than 50%, it is necessary to avoid the erosion of aluminum foil by air and water vapor during transportation;
This product is divided into two types: A and B, each with key features: A has a black appearance and a conventional coating thickness of 4-8 on both sides μ m. The conductivity is more prominent; The appearance of the B model is light gray, and the conventional coating thickness is 2-3 on both sides μ m. The coating area can be welded with fewer layers and the coating machine can identify skip gaps;
