2. Physical & Safety Features‌‌

  • Prismatic Pouch Construction‌: Built in a slim, rectangular polymer pouch format with dimensions approximately ‌7.0 × 46 × 148 mm‌, enabling integration into space-constrained yet power-hungry devices such as ‌portable medical monitors, industrial handhelds, and advanced audio recorders‌.
  • Lightweight & Durable‌: Weighs around ‌~98g‌, balancing high energy density with portability, suitable for field-deployable and wearable systems.
  • Flame-Retardant Encapsulation‌: Utilizes ‌UL-94V0 rated casing material‌ to suppress thermal propagation and enhance fire resistance under fault conditions.
  • Integrated Protection Circuit Module (PCM)‌: Equipped with multi-layer safeguards against:
    • Overcharge (cut-off at ‌4.25V ±0.05V‌)
    • Over-discharge (protection triggered below ‌3.0V‌)
    • Short circuit (response time <1ms)
    • Overcurrent (limits continuous discharge to ‌1C‌, i.e., 5.3A)
    • Temperature anomalies (thermal cutoff at ‌60°C‌ during discharge, ‌45°C‌ during charge)
  • Single-Series Configuration (1S)‌: Operates at nominal ‌3.7V‌, making it compatible with standard Li-ion systems while delivering extended runtime through high-capacity design.
  • Mechanical Resilience‌: Designed to withstand moderate vibration and flex stress, though ‌puncturing, bending, or crushing must be strictly avoided‌ to prevent internal short circuits and potential thermal runaway.

3. Charging & Maintenance Guidelines

  • Recommended Charging Method‌: Use a ‌CC/CV (constant current/constant voltage)‌ charger set to ‌4.2V ±0.05V‌. Initial charge current should be ‌0.5C (2.65A)‌ for optimal cycle life; maximum allowable charge current is ‌1C (5.3A)‌ for fast charging scenarios.
  • Charging Environment‌: Conduct charging in ‌well-ventilated, dry areas‌ between ‌0°C and 45°C‌. Avoid charging in high-humidity environments or enclosed spaces to reduce corrosion and insulation risks.
  • Discharge Management‌: Do not discharge below ‌3.0V‌ to prevent irreversible capacity loss and increased internal resistance. Devices should include low-voltage cutoff logic.
  • Storage Protocol‌:
    • For short-term (<1 month): Maintain charge level between ‌40–80%‌.
    • For long-term (>1 month): Store at ‌~50% state of charge (SoC)‌ in a cool, dry environment (‌15–25°C‌).
    • Recharge every ‌3 months‌ if idle to avoid deep discharge-induced dormancy or failure.
  • Handling Precautions‌: Avoid exposure to water, metal contact, or mechanical impact. Never disassemble or modify the cell.
  • End-of-Life Disposal‌: Recycle at certified e-waste facilities. ‌Do not incinerate or dispose of in household waste‌ due to fire hazard.
