Aluminum Oxide Used for lithium battery Diaphragm

What is ceramic diaphragm?
Ceramic finishing unique diaphragm: With PP, PE or multi-layer composite diaphragm as the matrix, the surface area is coated with a layer of nano-sized aluminum oxide product, which is closely bound to the substratum after unique process therapy. It can considerably enhance the heat resistance and safety and security of lithium-ion batteries. Ceramic coated unique diaphragm is specifically ideal for power batteries.

Demands for diaphragms for lithium-ion batteries:
The efficiency of the diaphragm identifies the inner resistance and also user interface framework of the battery, and after that determines the battery capacity, safety efficiency, fee and also discharge density and cycle efficiency.

As a result, the complying with characteristics need to be met:
Excellent chemical security: resistance to natural solvents.
Excellent mechanical residential or commercial properties: high tensile stamina as well as high puncture toughness.
Great thermal stability: low thermal contraction as well as high film breaking temperature level.
Electrolyte wettability: good compatibility with electrolyte and also high fluid absorption price.

As a sort of inorganic material, light weight aluminum oxide has high thermal security and chemical inertia, so it is an excellent selection for battery diaphragm ceramic coating.

Performance requirements of ceramic diaphragm for alumina:
1. The fragment dimension is uniform, which can be well glued to the diaphragm without obstructing the diaphragm aperture.
2. Alumina has high purity and also can not introduce pollutants, which impacts the inner atmosphere of the battery.
3. The need of crystal framework of alumina ensures the compatibility as well as wettability of alumina to electrolyte.

Advantages of layer alumina diaphragm:
Heat resistance:
Alumina coating has outstanding heat resistance and also can preserve the undamaged form of the diaphragm over 180 degrees Celsius.

High security:
The alumina coating can reduce the effects of the cost-free HF in the electrolyte as well as boost the acid resistance as well as safety of the battery.

High magnifying:
Nano-alumina can create solid solution in lithium battery, which can enhance the magnification and cycle efficiency.

Good wettability:
Nanometer alumina powder has good fluid absorption and also liquid retention capacity.

Unique self-turn-off qualities:
The closed-cell characteristic of polyolefin diaphragm is maintained to prevent safety and security dangers caused by thermal runaway.

Reduced self-discharge price:
The alumina finishing enhances the curvature of micropores and the self-discharge is less than that of the usual diaphragm.

Long cycle life: minimize the mechanical micro-short circuit in the cycle process and effectively improve the cycle life.
