High-Energy Semi-Solid Pouch Cell 25.5-58Ah ATOMFAIR®

These cells require storage in moisture-barrier vacuum-sealed packaging to prevent internal degradation. Operation demands a compatible battery management system (BMS) with over-discharge, over-current, and cell balancing protection.

• Storage Packaging: Store cells in moisture-barrier vacuum-sealed aluminum foil bags within anti-static cartons to maintain electrolyte stability.
• Temperature Limits: Avoid exposing cells to temperatures above 60°C for extended periods; charge only within 0°C to 50°C and discharge within -20°C to 60°C depending on the model.
• BMS Requirement: Always use a compatible BMS with over-discharge, over-current, and cell balancing protection to prevent electrical hazards.
• Pre-conditioning: Pre-condition new cells at 25°C before first use to ensure proper initial performance.
• Cycle Life Conditions: Achieve up to 1500 cycles at 80% SOH when operating at 0.5C charge/3C discharge within specified voltage and temperature ranges.

These steps guide the safe preconditioning, connection, and cycling of the semi-solid electrolyte pouch cells. Always follow the manufacturer's voltage and temperature limits to prevent damage or hazard.

1. Inspect cell
   Inspect the cell for physical damage, swelling, or deformation before handling.
2. Pre-condition cell
   Pre-condition the new cell by charging it to its nominal voltage at 25°C ambient temperature before first use.
3. Connect BMS
   Connect the cell to a compatible BMS with over-discharge, over-current, and cell balancing protection.
4. Charge cell
   Charge the cell at 1C rate to the maximum voltage (4.25V or 4.35V) within the specified charge temperature range.
5. Discharge cell
   Discharge the cell at up to 3C rate, monitoring voltage to remain above the minimum (2.7V or 2.75V).

The ATOMFAIR Powerful High-Energy-Density Battery Series provides compact pouch cells in 25.5Ah and 58Ah capacities, utilizing semi-solid electrolyte for safety and stable 1C/3C charge/discharge rates. It operates from -20°C to 60°C discharge and achieves up to 1500 cycles at 80% SOH, but requires a dedicated BMS and exhibits cycle-life variation between models.

Positive

• High Energy Density in Compact Pouch: Up to 58Ah capacity in a slim pouch format (10.0 mm thick) enables space-constrained integration in robotics and portable systems.
• Wide Temperature Operation Range: Discharge from -20°C to +60°C allows use in diverse indoor/outdoor robotic applications without active thermal management.

Trade-offs

• BMS Required for Safe Operation: A compatible battery management system with over-discharge, over-current, and cell balancing is mandatory to prevent damage and ensure cycle life.
• Cycle Life Variation Across Capacity: The 25.5Ah variant achieves 800 cycles at 80% SOH, while the 58Ah variant reaches 1500 cycles, affecting replacement scheduling and total cost of ownership.
