This battery series requires strict adherence to environmental and electrical safety limits to prevent thermal runaway or degradation. Cells must be stored in moisture-barrier packaging and operated only with a compatible BMS providing over-discharge, over-current, and cell balancing protection.

  • Storage Environment: Store cells in moisture-barrier vacuum-sealed aluminum foil bags within a dry, temperature-controlled environment to prevent electrolyte degradation.
  • BMS Requirement: Always use a compatible Battery Management System (BMS) with over-discharge, over-current, and cell balancing protection to maintain safe operation.
  • Charge Constraints: Charge the battery only within the manufacturer's recommended voltage range to avoid overvoltage conditions.
  • Thermal Exposure: Avoid exposing cells to excessive temperatures for extended periods to maintain thermal stability and reduce leakage risk.
  • Disposal Compliance: Dispose of end-of-life cells in accordance with local regulations for lithium-based batteries.

Follow these sequential steps to safely deploy and operate the semi-solid battery cells. Always use compatible charging and protection equipment to mitigate electrical hazards.

Required Equipment: Compatible Battery Management System (BMS) with over-discharge, over-current, and cell balancing protection, Compatible charger with adjustable voltage and current limits

  1. Inspect Packaging
    Inspect the moisture-barrier packaging for any breaches before opening to confirm cell integrity.
  2. Pre-condition Cells
    Pre-condition new cells at a suitable temperature as per manufacturer guidelines before first use.
  3. Connect BMS
    Connect the battery to a compatible BMS with over-discharge, over-current, and cell balancing protection.
  4. Charge Battery
    Charge the battery within the manufacturer's recommended voltage range using a compatible charger.
  5. Verify Discharge Limits
    Ensure the discharge current does not exceed the rated peak discharge duration and continuous discharge rate.
  6. Dispose Safely
    Dispose of end-of-life cells in accordance with local regulations for lithium-based batteries.

How does the energy density of the 6S configuration compare to the 18S configuration in the 3.95V semi-solid battery series?

The 6S configuration provides 250 Wh/kg, while the 18S configuration provides 260 Wh/kg. The 8S and 12S configurations each provide 255 Wh/kg. The 18S offers the highest energy density in the series.

What voltage and physical dimensions should I consider when selecting a configuration from the 28Ah semi-solid battery series?

The series offers nominal cell voltages of 23.7V (6S), 31.6V (8S), 47.4V (12S), and 71.1V (18S). Dimensions vary in length from 70.5mm to 206.5mm, with constant width 89mm and height 205mm. Weight ranges from 2650g to 7600g. Choose based on your system's voltage and space constraints.

What protective measures are required for operating the 3.95V semi-solid battery series at its peak discharge rate of 10C?

A compatible BMS with over-discharge, over-current, and cell balancing protection is mandatory. Do not exceed the rated peak discharge duration. Pre-condition new cells before first use and avoid extended exposure to excessive temperatures. Charge within the manufacturer's recommended voltage range.

The ATOMFAIR 3.95V 260Wh/kg Semi-Solid Battery Series (28Ah) offers high energy density with semi-solid electrolyte for enhanced safety, supports 2C charge and 5C continuous discharge, and is available in 6S to 18S configurations for flexible voltage integration in drones, robotics, and portable power systems.

Positive

  • High Energy Density 260Wh/kg: Enables longer runtime in lightweight designs such as UAVs and portable devices, reducing weight-to-energy ratio.
  • High Rate Capability up to 10C Peak: Supports 2C fast charging, 5C continuous discharge, and 10C peak discharge for power-demanding applications in robotics and electric equipment.

Trade-offs

  • Requires Compatible BMS: Must use a battery management system with over-discharge, over-current, and cell balancing protection to ensure safe operation and longevity.
  • Temperature and Pre-conditioning Sensitivity: Avoid prolonged exposure to excessive temperatures; pre-condition new cells at suitable temperature before first use to maintain performance.
