Battery Separator Aluminum Oxide | How to Choose Aluminum Oxide Coating for Lithium-ion Battery Separators?
High-temperature resistance:
Alumina coatings exhibit excellent high-temperature resistance, maintaining their diaphragm shape above 180 degrees Celsius.
2. High Security:
Alumina coating can neutralize free HF in the electrolyte, enhancing battery acidity resistance and improving safety.
3. High-performance Ratio
Nano-alumina can form a solid solution in lithium batteries, enhancing rate performance and cycling stability. 4. Good wettability:
Nano-alumina powder exhibits excellent liquid absorption and retention capabilities.
5. Unique Self-Shutoff Feature:
Maintained the closed-cell characteristic of the polyolefin separator to prevent thermal runaway and potential safety hazards.
6. Low self-discharge rate:
Alumina coating enhances microporous tortuosity, resulting in self-discharge lower than that of conventional separators.
7. Long cycle life:
Battery Separator Alumina | Reduces mechanical microshorts during the cycle process, effectively enhancing cycle life.
