Application:
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 for lithium polymer batteries:
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 steps for lithium polymer battery cell:
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
