Solar Lithium Polymer Battery Cell 602040 450mAh 3.7V Rechargeable Lipo Battery Pack

Main advantages:

High Safety:

The aluminum-plastic flexible packaging structure is safer than the metal casing of traditional liquid batteries and will not explode in the event of an abnormality.

Lightweight and Thin:

With a thickness of less than 1mm and a weight reduction of 40% compared to steel-cased batteries, it is suitable for space- and weight-sensitive devices (such as Bluetooth headsets and smart wearables).

Long Cycle Life:

With a cycle life of over 500, it is suitable for applications requiring frequent charging and discharging (such as Bluetooth headset charging stations).

Applications:

It is suitable for small electronic devices such as Bluetooth headsets, massagers, beauty devices, and sprayers, providing stable battery life.

Lipo battery's Advantages compared with Ni-Mh/Ni-CD batteries:

Energy Density:
The energy density of lithium-polymer batteries typically ranges from 150-250 Wh/kg, while that of nickel-metal hydride batteries is approximately 60-120 Wh/kg. With the same capacity, lithium-polymer batteries are smaller and lighter. ‌

Safety:
Ni-metal hydride batteries are more stable in short-circuit or high-temperature environments, with a melting point as high as 400°C, making them less prone to spontaneous combustion. Li-polymer batteries, due to their solid-state electrolyte, are theoretically more resistant to crushing and puncture, but may present a risk of thermal runaway in high-temperature environments. ‌

Cycle Life:
Ni-metal hydride batteries can achieve up to 300-500 charge cycles, while lithium-polymer batteries generally exceed 1,000 cycles, with some reaching several thousand. ‌

Cost:
Ni-metal hydride batteries have lower production costs and a significant price advantage. Li-polymer batteries, due to their complex materials and processes, have higher initial manufacturing costs, but their price gradually decreases with large-scale production.
