Product features:
1. High energy density
The weight of lithium polymer batteries is half that of nickel cadmium or nickel hydrogen batteries of the same capacity, and the volume is 40-50% that of nickel cadmium and 20-30% that of nickel hydrogen.
2. High voltage
The operating voltage of a single lithium polymer battery is 3.7V (average), which is equivalent to three nickel cadmium or nickel hydrogen batteries connected in series.
3. Good safety performance
The outer packaging is aluminum-plastic packaging, which is different from the metal shell of liquid lithium batteries. Due to the use of flexible packaging technology, internal quality hazards can be immediately displayed through deformation of the outer packaging. Once a safety hazard occurs, it will not explode but only swell.
4. Long cycle life
Under normal conditions, the charge and discharge cycle of lithium polymer batteries can exceed 500 times.
5. No pollution
Lithium polymer batteries do not contain harmful metal substances such as cadmium, lead, mercury, etc.
6. No memory effect
The memory effect refers to the phenomenon in which the capacity of nickel cadmium batteries decreases during the charging and discharging cycles. Lithium polymer batteries do not exhibit this effect.
7. Fast charging
Using a constant current and constant voltage charger with a rated voltage of 4.2V can fully charge lithium polymer batteries within one to two hours.
8. Complete range of models
Complete range of models, wide capacity and size range, can be designed according to customer needs, with a single thickness of 0.8-10mm and a capacity of 40mAh~20Ah.
Application:
Portable Devices:
Laptops and Notebooks: Li-poly batteries contribute to the sleek and lightweight design of modern laptops.
Portable Game Consoles: These devices rely on Li-poly batteries for extended gaming sessions without being tethered to a power outlet.
E-readers: Devices like Kindles use Li-poly batteries to ensure long reading times on a single charge.
Industrial and Commercial Applications:
Automated Guided Vehicles (AGVs): These vehicles use Li-poly batteries to navigate and perform tasks in warehouses and manufacturing environments.
Robotics: Li-poly batteries provide the power needed for robots to operate efficiently in various industrial and research settings.
Tools and Equipment: Cordless tools and other equipment often use Li-poly batteries for increased portability and runtime.
