Main Advantages:
Advantages of the 502540 Lithium Polymer Battery
The extremely thin and flexible design utilizes an aluminum-plastic film soft-package package, boasting a thickness of only 5mm. It can be bent 90° or conform to curved surfaces, making it suitable for space-sensitive devices such as smartwatches (such as the Apple Watch Ultra) and wireless earbuds (such as the AirPods Pro).
High-rate discharge performance with low internal resistance (<100mΩ) supports 2C continuous discharge (1A) and instantaneous discharge up to 5C (2.5A), making it suitable for applications requiring high instantaneous currents such as drones and remote-controlled cars.
Highly safe solid-state/gel electrolytes are non-leakage-resistant, resulting in only swelling and no explosion during thermal runaway, and pass needle penetration testing.
Lightweight, making it suitable for weight-sensitive wearables and portable electronics.
Advantages of the 14500 Lithium-ion Battery:
The long-cycle lithium iron phosphate version boasts a cycle life
of over 2,000 cycles, four times that of lithium polymer batteries,
making it suitable for power tools and energy storage devices that
require frequent charging and discharging.
Better low-temperature performance: At -20°C, the capacity retention rate is about 80%, while lithium polymer batteries need improved electrolyte to achieve a capacity retention rate of 60% at -30°C. This makes it more reliable in northern winters or industrial low-temperature environments.
