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.
