Advantages for lithium polymer batteries:
Safety:
Solid or gel electrolytes are used instead of liquid electrolytes
to avoid leakage and combustion risks. Even if short-circuited or
overheated, it will only swell and deform instead of explode.
Equipped with multiple protection mechanisms (such as
overcharge/discharge protection, PTC components, etc.),
international certification (such as IEC 62133-2 standard) ensures
safe use.
Lightweight design:
The aluminum-plastic soft packaging structure reduces the weight of
the battery by 20%-40%, and the thickness can be less than 0.5mm,
which is suitable for ultra-thin devices (such as folding screen
mobile phones and wearable devices). Compared with traditional
liquid batteries, polymer batteries have a smaller volume while
maintaining the same capacity.
Performance optimization:
Some models support 2C rate fast charging (such as some polymer
lithium batteries), with an energy density, and a battery life
extended by 1.2 hours.
Common applications in smart devices include mobile phones, drones, and other scenarios with high requirements for form and efficiency
Typical applications Medical equipment: Breast pump, handheld terminal
Digital products: Mobile power, drones, smart locks
Industrial equipment: Monitoring equipment, instruments and meters
