Store cells in a cool, dry environment within the manufacturer's recommended temperature range to prevent degradation. Always use a compatible Battery Management System (BMS) with over-discharge, over-current, and cell balancing protection.

  • Temperature Exposure: Avoid exposing cells to excessive temperatures for extended periods to prevent thermal runaway or capacity loss.
  • Moisture Protection: Keep cells in moisture-barrier vacuum-sealed packaging until use to prevent electrolyte degradation.
  • Charge Voltage Limits: Charge within the manufacturer's recommended voltage range to avoid overcharge damage.
  • Discharge Rate Limits: Do not exceed the rated peak discharge duration to prevent overheating and cell damage.
  • Disposal Compliance: Dispose of cells in accordance with local regulations for lithium-ion batteries.

Follow these steps to safely prepare and deploy the semi-solid battery cells for first use. Proper handling ensures optimal performance and minimizes safety risks.

Required Equipment: Compatible Battery Management System (BMS), Charger with adjustable voltage and current settings

  1. Inspect Packaging
    Inspect the moisture-barrier packaging for any punctures or tears before opening the cell.
  2. Pre-condition Cell
    Pre-condition new cells at a stable room temperature for at least two hours before first use.
  3. Connect BMS
    Connect the cell to a compatible Battery Management System with over-discharge and over-current protection.
  4. Set Charge Parameters
    Set the charger to the manufacturer's recommended voltage and current limits for the specific pack configuration.
  5. Monitor Initial Charge
    Monitor cell temperature during the initial charge cycle and ensure it remains within safe operating limits.
  6. Verify Balancing
    Verify that all cells are balanced after the first full charge using the BMS status indicators.
  7. Store Safely
    Store unused cells in a cool, dry location away from flammable materials and direct sunlight.

How does the semi-solid electrolyte in the ATOMFAIR 3.95V 26Ah series affect the rate capability versus ultra-high energy density?

The semi-solid electrolyte enables both ultra-high energy density (up to 300 Wh/kg on the 18S model) and high rate capability (5C continuous, 8C peak discharge) simultaneously, indicating no significant trade-off between energy density and power delivery for this commercial-grade cell design. All four configurations (6S, 8S, 12S, 18S) maintain identical 1C charge and 5C/8C discharge ratings.

Can the ATOMFAIR 3.95V semi-solid battery be directly integrated into existing drone or robotics power systems without modifying the battery management system?

No, the battery requires a compatible BMS with over-discharge, over-current, and cell balancing protection as explicitly stated in the product notice. Direct integration is not recommended unless the existing system's BMS supports these protections and the voltage range matches the pack voltage (23.7V to 71.1V depending on model).

What are the critical storage and preconditioning requirements for the ATOMFAIR semi-solid pouch cells to ensure safe operation and prevent capacity loss?

Cells must be stored in moisture-barrier vacuum-sealed aluminum foil bags and preconditioned at a suitable temperature before first use. The notice also requires charging within the manufacturer's recommended voltage range, avoiding prolonged exposure to excessive temperatures, and never exceeding the rated peak discharge duration. Always follow local regulations for disposal.

The ATOMFAIR 3.95V Semi-Solid Battery series offers up to 300 Wh/kg energy density with 5C continuous discharge capability, but requires careful thermal management and a dedicated BMS due to 1C charge limit and sensitivity to temperature extremes.

Positive

  • Ultra-High Energy Density (300 Wh/kg): Achieves up to 300 Wh/kg in the 18S configuration, enabling significant weight reduction for UAVs and portable devices while maintaining high capacity.
  • High Rate Capability with Semi-Solid Electrolyte: Supports 5C continuous discharge and 8C peak discharge with enhanced safety from semi-solid electrolyte, reducing leakage risk and improving thermal stability.

Trade-offs

  • Limited Charge Rate and BMS Requirement: Maximum charge rate is 1C, requiring longer charge times. A compatible BMS with over-discharge, over-current, and cell balancing protection is mandatory for safe operation.
  • Environmental Sensitivity and Pre-conditioning: Cells must be protected from excessive temperatures and pre-conditioned at suitable temperature before first use. Exceeding rated peak discharge duration or voltage ranges can compromise safety and performance.
