Key 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.

Comparison 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.
