About conductive agent?

The key material in the positive electrode of lithium battery-aluminum foil. Battery aluminum foil is used as a current collector for lithium-ion batteries. Typically, the lithium-ion battery industry uses rolled aluminum foil as the positive electrode current collector.

Advantages of carbon-coated aluminum foil in lithium battery applications:

Inhibit battery polarization, reduce thermal effects, and improve rate performance.

Reduce the internal resistance of the battery, and significantly reduce the increase in dynamic internal resistance during the cycle.

Improve the consistency and increase the cycle life of the battery.

Improve the adhesion between the active material and the current collector, and reduce the manufacturing cost of the pole piece.

Protect the current collector from being corroded by the electrolyte.

Improve the processing performance of lithium iron phosphate and lithium titanate materials.

Performance advantages of carbon-coated aluminum foil/copper foil:

Significantly improve the consistency of battery pack use and greatly reduce the cost of battery packs.

Improve the adhesive adhesion between the active material and the current collector, the material is soft, easy to process, and reduce the manufacturing cost of the pole piece.

Reduce polarization, increase rate and gram capacity, improve battery performance; protect current collector, prolong battery life.
