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.
