Polymer batteries, recognized for their superior energy density, design flexibility, and safety performance, have become the core power solution for drones, consumer electronics, power tools, and beyond.
(1) High Energy Density: Balancing Endurance and Portability
With an energy density of 100–260Wh/kg, polymer batteries outperform traditional batteries, storing more power in the same volume. For example:
A 3.7V/5000mAh pouch cell at just 4.5mm thickness delivers 12+ hours of smartphone runtime, seamlessly merging slim designs with long endurance.
Critical for weight-sensitive applications (e.g., drones gain 20% payload capacity with lightweight polymer cells).
(2) Flexible Design: Adapting to Any Form Factor
Unlike rigid cylindrical batteries, polymer batteries use flexible aluminum-plastic film encapsulation, enabling:
Ultra-thin profiles (down to 2mm) for wearables (smartwatches, AR glasses).
Custom shapes (trapezoidal/curved) boosting 30% space utilization in drone battery compartments.
Modular configurations (3S/11.1V, 4S/14.8V) to meet diverse voltage needs.
(3) Low Self-Discharge: Reliable Long-Term Storage
With a <3% monthly self-discharge rate (vs. 15% for NiMH), polymer batteries excel as backup power:
Industrial backup systems retain 3+ months of charge, reducing maintenance.
Inventory management only requires quarterly top-ups, cutting costs.
(1) Capacity (Ah): Real-World Energy Supply
Rated capacity: Tested at 25°C/0.2C discharge (e.g., 20Ah = 2A for 10 hours).
Actual capacity:
-20°C: Capacity drops 40%, but low-temperature electrolyte additives recover 80%.
High-rate discharge (10C+): 10–15% loss; low-impedance cells (<10mΩ) mitigate drop.
(2) C-Rate: Power Delivery for Demanding Applications
Charging: 0.5C (20Ah @10A) for maintenance; 1C (20A) reaches 80% in 1 hour (requires balanced charger).
Discharging:
Consumer electronics: 2C (40A) handles CPU peaks.
Drones/tools: 10C+ (200A) ensures <5% voltage dip during motor startup.
(3) Operating Temperature: Full-Environment Adaptability
Range: -20°C to 60°C, covering most industrial/consumer uses.
Extreme conditions:
>60°C: Ceramic separators raise thermal runaway threshold to 300°C+.
<-20°C: Silicon-carbon anodes maintain 60% capacity at -40°C for Arctic operations.
(1) Consumer Electronics
Phones/tablets: 3.7V cells with 18W fast charging (30 min to 60%) and <8mΩ impedance reduce heat.
Wearables: ≤3mm cells extend runtime by 30% for earbuds/smartwatches.
(2) Drones & RC Models
25C discharge (e.g., 4000mAh @100A) ensures stable flight under peak loads.
20% lighter than cylindrical cells, adding 15+ minutes flight time.
(3) Power Tools
10C discharge prevents drill stalling; <5μs overcurrent protection safeguards motors.
(4) Industrial & Energy Storage
Backup systems: 8+ hours runtime during outages.
IoT devices: Deep discharge to 2.5V suits outdoor sensors.
(1) Triple Safety Protections
Overcharge cutoff at 4.2V±0.05V.
Short-circuit shutdown in 0.1s (<5A current).
Thermal cutoff at >65°C.
(2) Charging Best Practices
Balanced chargers keep cell voltage variance <50mV.
0.5C slow charging extends cycle life to 500+ cycles; limit 1C fast charging to <20% usage.
(3) Storage & Transport
Store at 40–60% SOC, 25°C±5°C, <60% humidity.
UN38.3 certified; <10kg/box for air/sea freight compliance.
