Applications
- MP3/MP4 player: As a mainstream portable device battery, it provides long-term battery life support.
- GPS tracker: Used for outdoor positioning equipment, requiring stable power supply performance.
- Bluetooth headset/speaker: Adapt to wireless devices, emphasizing lightweight and long battery life.
Storage Precautions
- Temperature and humidity: The ideal storage temperature is 15-25℃. Avoid high temperature (＞35℃) or humid environment. High temperature will accelerate battery aging, and humidity may cause short circuit or corrosion.
- Power management: It is recommended to keep the power at 50% for long-term storage, and avoid full charge or over discharge. Regular charge and discharge cycles can maintain battery health.
- Isolation and protection: Keep away from fire and flammable materials. Use fireproof containers or fireproof bags when storing, and ensure good ventilation.
Production Process
Positive electrode material preparation: Using ternary materials (composite oxides of nickel, cobalt and manganese) as active materials, positive electrode plates are made through stirring, coating and other processes.
Negative electrode materials: Carbon materials such as graphite are usually used, and negative electrode plates are made through coating and rolling.
Electrolyte: It is a mixture of lithium salt (such as lithium hexafluorophosphate) and organic solvent, which directly affects the performance of the battery.
Key Production Steps
- Slurry preparation: The positive and negative active materials are mixed with the binder to form a uniform slurry, which is then coated on metal foil (such as copper foil or aluminum foil) after being stirred by a vacuum mixer without bubbles.
- Pole plate processing: The coated pole plates are dried, rolled (densified) and cut to form pole plates of specific sizes.
- Battery assembly: The positive and negative pole plates, separators, etc. are assembled into a battery cell and injected with electrolyte.
- Formation and testing: Activate battery performance through charge and discharge cycles and screen out unqualified products.
