Product Introduction: 

HPA For Lithium-Ion Battery Electrodes Separator is a white crystalline powder. High purity alumina refers to ultra-micro powder material with a purity of 99.99% or more and uniform particle size, which is porous, highly dispersible, insulating and heat resistant.

The application of HPA For Lithium-Ion Battery Electrodes Separator in the surface coating of materials such as lithium cobaltate, lithium manganate, lithium titanate and lithium iron phosphate can also significantly reduce the interfacial impedance and provide additional electron transport channels, thus effectively preventing the electrolyte from corroding the electrolyte. In addition, it can accommodate changes in particle volume during Li + de-embedding to prevent damage to the electrode structure.

Performance requirements of HPA For Lithium-Ion Battery Electrodes Separator:

1) Uniform particle size, which bonds well to the diaphragm without blocking the diaphragm aperture.

2) High purity, which cannot introduce impurities that could affect the internal environment of the battery.

3) The requirements of the alumina crystal structure to ensure the compatibility and wettability of the alumina to the electrolyte.

Advantages of Lithium-Ion Battery Electrodes Separator with HPA:

1) High temperature resistance

The alumina coating has excellent resistance to high temperatures, maintaining the diaphragm intact above 180 degrees Celsius.

2) High safety 

The alumina coating can neutralise free HF in the electrolyte, enhancing the acid resistance of the battery and improving safety.

3) High multiplicity

Nano alumina can form solid solution in lithium batteries, improving multiplicity and cycle performance.

4) Good wettability

Nano alumina powder has good liquid absorption and retention ability.

5) Unique self-closing characteristics

The closed pore characteristics of the polyolefin diaphragm are maintained to avoid safety hazards caused by thermal runaway.

6)Low self-discharge rate

The alumina coating increases the curvature of the micro-pores, resulting in lower self-discharge than ordinary diaphragms.

7) Long cycle life

Reduced mechanical micro-short circuits during cycling, effectively enhancing cycle life.
