Key Advantages
  • High Energy Density: Ternary materials provide superior energy density for longer runtime in compact spaces
  • Lightweight & Flexible Form Factor: Polymer electrolytes enable thin, flexible, and custom-shaped battery designs
  • High Discharge Platform & Fast Charging: Average operating voltage exceeding 3.7V with low internal resistance for high-rate performance
  • Cycle Life & Safety: Polymer design with protection circuits ensures structural stability; requires BMS for thermal management
Product Measurements

Protection Circuit Module (PCM) Functions
  • Overcharge Protection: Cuts off charging circuit when voltage reaches 4.2V-4.25V to prevent cell bulging, fire, or explosion
  • Over-Discharge Protection: Disconnects discharge circuit at 2.5V-2.3V to prevent copper foil dissolution and permanent capacity decay
  • Overcurrent Protection: Detects and shuts down MOS switch when current exceeds safe threshold (e.g., 3A) to prevent overheating
  • Short Circuit Protection: Cuts off circuit within milliseconds during short circuit conditions to prevent fire or explosion
  • Temperature Protection: NTC thermistors limit charging/discharging in extreme temperatures (>60℃) for improved safety
  • Battery Balancing: Active or passive balancing in multi-cell packs ensures consistent voltage across all cells
Applications
Bluetooth Earphones - Compact size fits charging cases for extended listening time
Dash Cam - Stable operation in high-temperature environments for continuous recording
Portable Speakers & Walkie-Talkies - Provides all-day power with reliable performance
Power Banks & Locators - Lightweight design with high charging efficiency
Smart Bracelets & Beauty Devices - Flexible packaging fits irregular spaces with high safety
DIY Electronics Projects - Ideal for upgrading old equipment and extending device lifespan
