Rechargeable Li-Polymer Battery 403048 3.7V 600mAh 2.22wh Lithium Cell For Wareable Device

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
