Semi-Solid Pouch Battery 3.95V 8Ah 250Wh/kg ATOMFAIR®

Store cells in a moisture-barrier vacuum-sealed environment at temperatures between 10°C and 30°C to prevent degradation. Always operate with a compatible BMS that provides over-discharge, over-current, and cell balancing protection.

• Temperature Sensitivity: Avoid exposing the battery to temperatures above 60°C or below -20°C during storage or operation to prevent thermal runaway or capacity loss.
• Charge Voltage Limits: Charge within the manufacturer's recommended voltage range of 4.2V per cell maximum to avoid overvoltage damage.
• Discharge Rate Constraints: Do not exceed the rated peak discharge current of 15C for more than the specified short duration to prevent overheating and cell degradation.
• BMS Requirement: Integrate a BMS that monitors individual cell voltage, temperature, and current to ensure safe operation within specified limits.
• Disposal Compliance: Dispose of the battery in accordance with local regulations for lithium-ion or semi-solid electrolyte cells to avoid environmental contamination.

Follow these steps to safely deploy and use the semi-solid battery pack. Always use a compatible BMS and charger to prevent damage or injury.

Required Equipment: Compatible BMS (with over-discharge, over-current, and cell balancing), Manufacturer-recommended battery charger

1. Inspect Packaging
   Inspect the moisture-barrier vacuum-sealed aluminum foil bag for any punctures or damage before opening.
2. Connect BMS
   Connect the battery to a compatible BMS that provides over-discharge, over-current, and cell balancing protection.
3. Charge Battery
   Charge the battery using a manufacturer-recommended charger within the specified voltage range (4.2V per cell maximum) at a 1C rate.
4. Pre-condition Cells
   Pre-condition new cells at a suitable temperature (10°C to 30°C) for at least 24 hours before first use to stabilize the electrolyte.
5. Monitor Temperature
   Monitor battery temperature during operation and avoid extended exposure to ambient temperatures above 45°C or below 0°C.
6. Respect Discharge Limits
   Do not exceed the continuous discharge rate of 7C or the peak discharge rate of 15C for more than the rated short duration.

The ATOMFAIR 3.95V 250Wh/kg Semi-Solid Battery 8Ah Series (models AF3950806S through AF3950818S) offers ultra-high energy density (250-260 Wh/kg) in a pouch-cell format with semi-solid electrolyte, supporting 1C charge, 7C continuous discharge, and 15C peak discharge across four voltage configurations (23.7V to 71.1V).

Positive

• Ultra-high energy density 250 Wh/kg: Achieves 250 Wh/kg (260 Wh/kg for 18S model), enabling extreme lightweight design for UAVs, robotics, and portable power stations.
• High rate capability up to 15C peak: Supports 1C charge, 7C continuous discharge, and 15C peak discharge, suitable for high-demand applications requiring rapid power delivery.

Trade-offs

• Requires compatible BMS for protection: Mandatory use of a BMS with over-discharge, over-current, and cell balancing protection; adds system complexity and cost.
• Sensitive to temperature and handling: Cells must be preconditioned before first use, kept within specified temperature range, and peak discharge duration must not be exceeded to avoid degradation.
