Application:
Smart devices:
Suitable for devices with moderate battery life requirements such as fingerprint locks, cervical massagers, microphones, etc. The battery has a standard voltage of 3.7V and supports working in an environment of -10~60℃. The cycle life is up to 500 cycles, which can meet daily use needs.
Consumer electronics:
Can be expanded to small household appliances such as aromatherapy machines and beauty devices. Its lightweight design (10×20×40mm) and low-temperature working characteristics (-10℃ start-up) are suitable for outdoor scenes in winter.
Industrial scene:
Outstanding performance in medical equipment (such as detectors, scanning pens). The battery has high consistency and low self-discharge characteristics (monthly self-discharge rate ≤5%), and can maintain stable performance after long-term storage.
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
