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: Traditional 3.7V li-polymer offers higher capacity and energy density in the same dimensions, supporting longer runtime for compact devices.
  • Wider Application Compatibility: Matches the charging and discharging logic of most small smart devices, with better compatibility and simpler circuit design.
  • 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.
Applications
Bluetooth Devices: Speakers, headsets, remote controls
Beauty & Personal Care: Facial brushes, beauty devices, hydrating devices
Personal Care Appliances: Electric toothbrushes, shavers, hair clippers
