Main Advantages of Lithium Polymer Batteries
  • Flexible shape customization
  • Lightweight & slim profile
  • High safety with soft pouch structure
  • Low self-discharge rate
  • Long cycle life
  • No memory effect
  • Stable discharge performance
  • Suitable for miniaturized smart devices
  • Easy to integrate with wires & connectors
  • Full certifications: IEC62133, UN38.3, CE, RoHS
Advantages vs 3.2V LiFePO4 Batteries
  • Higher Nominal Voltage: 3.7V lithium polymer provides higher working voltage than 3.2V LiFePO4, delivering stronger power output and better performance in small electronics.
  • Higher Energy Density in Same Size: Traditional 3.7V li-polymer offers higher capacity and energy density in the same dimensions, supporting longer runtime for compact devices.
  • Wider Application in Consumer Electronics: Matches the charging and discharging logic of most small smart devices, with better compatibility and simpler circuit design.
  • More Mature Mass Production: Stable supply chain, lower cost, and higher consistency for mass production compared to LiFePO4 polymer in small-capacity sizes.
  • Better Low-Temperature Performance: Performs more stably in cold environments than most 3.2V LiFePO4 batteries, making it suitable for outdoor and portable devices.
