What is a ceramic diaphragm. A special ceramic coating diaphragm uses PP,PE or multi-layer composite as the matrix. The surface of the diaphragm is then coated with a nano-sized layer made from aluminum oxide. This is closely adhered to the substrate by special processes. The high temperature safety and reliability of lithium-ion cells can be significantly improved by using this coating. A ceramic-coated special diaphragm can be used for power batteries.
Diaphragms required for lithium-ion batteries
The diaphragm’s performance determines the interface structure and internal resistance of the battery. This determines its capacity, safety performance, charge density, cycle performance, and cycle efficiency.
These characteristics must be fulfilled:
Chemical stability is excellent: Resistance to organic solvents.
Excellent mechanical properties, high tensile strengths and puncture strength.
Excellent thermal stability. Low thermal shrinkage, high film breaking temperature.
The electrolyte’s wettability is good for compatibility and low liquid absorption.
aluminium oxide, a type of inorganic material, is good for ceramic coatings on battery diaphragms.
Ceramic diaphragm for Alumina:
1. Particle size is consistent, so they can be glued well to the diaphragm.
2. Alumina’s purity is high and it can be used without introducing impurities that could affect the internal environment of the batteries.
3. It is necessary for alumina crystal to be compatible with an electrolyte.
Benefits of coating aluminum diaphragm:
Resilience to extreme temperatures
It is resistant to extreme high temperatures, and retains its original shape above 180 degrees Celsius.
Secure:
An alumina-coated battery can reduce the free HF and increase safety and acid resistance.
High magnification
A solid solution of nano-alumina is possible in lithium battery. This can enhance the cycle efficiency and magnification.
Good wettability:
Nanometer-sized alumina powder is very liquid absorbent and retains liquid well.
Unique self-turn-off characteristics:
Polyolefin diaphragms have a closed-cell design to prevent thermal runaway.
Low self-discharge rate:
Because of its curvature, micropores are more curvy with alumina than the standard diaphragm. The self-discharge rate is also lower than the one caused by the common diaphragm.
Increase the lifespan of your cycles by increasing the number of cycle lives.
Aluminum oxide Price
Price is affected by many things, such as the demand and supply in the market and industry trends. Economic activity and market sentiment are also important.
