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.
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).
With a cycle life of over 500, it is suitable for applications requiring frequent charging and discharging (such as Bluetooth headset charging stations).
Lithium-ion Batteries: The cycle life can vary depending on the specific chemistry and manufacturing process. Some types may experience a gradual decline in capacity over many cycles.
LiFePO4 Batteries: Known for their long cycle life and high durability. They maintain high capacity over many charge-discharge cycles, making them suitable for applications where long-term reliability is important.
The cost of both types varies depending on production scale, raw material prices, and demand. LiFePO4 batteries may have a higher initial cost but their longer cycle life and lower maintenance requirements can offset this over time.
Lithium-ion Batteries: Widely used in portable electronics, electric vehicles, and energy storage systems due to their high energy density.
LiFePO4 Batteries: Often used in applications where safety is a top priority, such as electric buses, marine applications, and energy storage systems for renewable energy.
