Uses of Lithium Iron Phosphate

It is mainly used as a cathode material in the manufacture of lithium-ion batteries for mobile phones, laptops and other portable electronic devices.

Lithium Ion Batteries as Cathode Materials: Advantages of Carbon Coated Aluminum Foil in Lithium Battery Applications

1. Remove battery bias, reduce thermal effects and improve performance;

p>< p>2. Reduce the internal resistance of the battery and significantly reduce the increase in dynamic internal resistance during cycling;

3. Improve consistency and increase battery life; >

4. Improving the adhesion between the active material and the current collector reduces the manufacturing cost of the pole piece;

5. Protects the current collector from electrolyte corrosion;

6. Improves the processing properties of iron phosphate andtitanate lithium materials.

Conductive Coating

The use of functional coatings to treat the surface of conductive battery substrates is a revolutionary technological innovation. Carbon coated aluminum foil/copper foil is to use dispersed nanoscale conductive graphite and carbon. The coated particles are evenly and thinly coated on aluminum foil/copper foil. It can provide excellent static conductive properties and collect micro-currents from active materials, thereby greatly reducing the contact resistance between the positive/negative electrode material and the current collector, improving the adhesion between the two and reducing the amount of material adhesion. The agent can significantly improve overall battery performance.

There are two types of coatings: water-based (aqueous system) and water-basedoil (organic solvent system).

The performance advantages of carbon-coated aluminum foil/copper foil can significantly improve the consistency of battery usage and significantly reduce battery costs. For example:

·Significantly reduce the increase in dynamic internal resistance of the battery; ·Improve the consistency of battery voltage difference; ·Extend battery life; ·Reduce considerably the cost of the battery.

2. Improve the adhesion between active materials and current collectors and reduce the manufacturing cost of pole pieces. Such as:

· Improving the adhesion of cathode materials and collectors using aqueous systems; · Improve the adhesion of cathode materials and collectors at the nanometer or submicron scale; · Improve the adhesion of lithium titanate or other highadhesions between the negative capacitance electrode material and collector; Improve the qualification rate of pole pieces and reduce the manufacturing cost of pole pieces.

After using coated aluminum foil of carbon, the adhesion of the pole piece increased from the original 10 gf to 60 gf (using 3M tape or hundred grid knife method), the adhesion is significantly improved.

3. Reduce bias, increase rate and gram capacity, and improve battery performance. For example:

· Partially reduce the proportion of binder in the active material and increase the gram capacity; · Improve the electrical contact between the active material and the current collector; · Reduce polarization and improve performancepower.

Among them, C-AL is carbon-coated aluminum sheet, E-AL is aluminum sheet etched and U-AL is bare aluminum. sheet

4. Protect the current collector and extend battery life. Such as:

· Prevent collector corrosionCorrosion and oxidation; Increases the surface tension of the current collector and improves the easy coating performance of the current collector; Can replace the more expensive engraved sheet or replace the original standard sheet with a thinner sheet.
