Cycle Life: Supports over 1000 charge-discharge cycles, maintaining stable performance even with long-term use.
Compatibility: Compatible with a variety of management boards, suitable for mobile power banks, beauty devices, and other medical devices.
Applications:
Mobile Power Banks: Replace traditional battery cells, improving battery life and reducing device size.
Medical Devices: Handheld devices, such as beauty devices, require a balance between battery life and safety.
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.
