Applications
Consumer Electronics
- Smartphones and Tablets: Primary power source enabling long battery life and compact designs
- Wearable Devices: Smartwatches and fitness trackers with extended use without significant weight
- Cameras: Digital cameras supporting high-energy operations like video recording
Renewable Energy Systems
Energy Storage Systems: Store excess energy generated by renewable sources like solar and wind
Ternary Lithium Polymer Technology
Utilizes nickel-cobalt-manganese (NCM) or nickel-cobalt-aluminum (NCA) cathode materials, making them a mainstream choice for both power and consumer battery applications.
Medical Device Compatibility
Long Cycle Life & Low Maintenance
Typical cycle life of 1000-2000 cycles (2-4 times lithium cobalt oxide), reducing battery replacement frequency for long-term medical devices like ECG monitors and diagnostic equipment.
Temperature Performance
Maintains over 70% discharge efficiency from -20℃ to 60℃, suitable for outdoor emergency defibrillators and cold chain transported diagnostic equipment.
High-Power Capability
Supports high-current charging and discharging for emergency equipment such as defibrillators with high-voltage instantaneous discharge and ventilators with peak starting power.
Enhanced Safety
Superior thermal stability with higher thermal runaway threshold during overcharging, short circuits, and punctures, making them ideal for wearable ECG monitors and portable ultrasound devices.
