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.
Difference for lithium battery and LiFePO4 battery:
Lithium-ion Batteries: The cycle life of lithium-ion batteries can vary depending on the specific chemistry and manufacturing process. Some types may experience a gradual decline in capacity over many cycles.
LiFePO4 Batteries: LiFePO4 batteries are known for their long cycle life and high durability. They can maintain a high capacity over many charge-discharge cycles, making them suitable for applications where long-term reliability is important.
The cost of both types of batteries can vary depending on factors such as production scale, raw material prices, and demand. In general, LiFePO4 batteries may have a higher initial cost compared to some lithium-ion batteries, but their longer cycle life and lower maintenance requirements can offset this cost over time in certain applications.
Lithium-ion Batteries: Due to their high energy density, lithium-ion batteries are widely used in portable electronics, electric vehicles, and energy storage systems.
LiFePO4 Batteries: LiFePO4 batteries are often used in applications where safety is a top priority, such as electric buses, marine applications, and energy storage systems for renewable energy. They are also popular in industrial and commercial settings, such as UPS systems and emergency lighting.
Application areas:
Bluetooth earphones, smart wearables, GPS navigation devices, POS machines, power banks, learning devices, tablets, car navigation, MP3,MP4,MP5, Card insertion speaker, wireless mouse, Xiaomi display screen PSP built-in battery, Apple peripheral power supply, tablet computer, mobile DVD, laptop battery, wireless monitoring device, medical equipment, various instruments and meters, LED lamps, traffic signs, portable small appliances, various DIY instruments and meters, metal detectors, and other digital battery products.
