Key Features & Advantages

  • High Power Output: Up to 5C max discharge rate (35Ah model) for demanding applications.
  • Ultra-Long Cycle Life: 2000 cycles at 80% SOH for 50Ah model, reducing total cost of ownership.
  • Wide Temperature Range: Discharge from -20°C to +65°C, suitable for harsh environments.
  • Flexible Sizing: Three pouch formats to fit various battery pack designs – from portable power to EV modules.

APPLICATION SCOPE: Electric motorcycles, e-scooters, electric mopeds, e-bikes, commuter two-wheelers, and light electric vehicles requiring high power output, long cycle life, and reliable semi-solid battery technology for daily riding, urban mobility, and extended range.
PACKAGING: Moisture-barrier vacuum-sealed aluminum foil bags, individually packed in anti-static cartons. Custom packaging for volume orders available.
IMPORTANT NOTICE: For optimal performance and safety, operate within specified voltage ranges. Avoid sustained temperatures above the recommended limit. Always use a BMS with overcurrent, short-circuit, and temperature protection. Pre-condition cells at 25°C before first use. High-rate discharge may require active thermal management.

Store cells in a cool, dry environment within the recommended temperature range to prevent degradation. Always use a Battery Management System (BMS) with overcurrent, short-circuit, and temperature protection during operation.

  • Voltage Operating Limits: Operate cells strictly within the specified voltage range to avoid overcharge or deep discharge damage.
  • Temperature Constraints: Avoid sustained temperatures above the recommended limit and pre-condition cells at 25°C before first use.
  • Moisture Sensitivity: Keep cells sealed in moisture-barrier packaging until use to prevent internal contamination.
  • Thermal Management Requirement: High-rate discharge may require active thermal management to maintain safe operating temperatures.
  • BMS Protection: Always integrate a BMS with overcurrent, short-circuit, and temperature protection for safe operation.

Follow these steps to safely prepare and operate the battery cells for first use. Proper initialization ensures optimal performance and longevity.

Required Equipment: Battery Management System (BMS) with overcurrent, short-circuit, and temperature protection, Active thermal management system (e.g., cooling fan or heat sink)

  1. Inspect Packaging
    Inspect the moisture-barrier vacuum-sealed packaging for any signs of damage or leakage before opening.
  2. Pre-condition Cells
    Pre-condition the cells at 25°C for at least 2 hours before first use to stabilize internal chemistry.
  3. Connect BMS
    Connect a compatible Battery Management System with overcurrent, short-circuit, and temperature protection to the cell terminals.
  4. Verify Voltage
    Verify that the cell voltage is within the specified operating range using a calibrated multimeter.
  5. Apply Thermal Management
    Apply active thermal management if the application requires high-rate discharge above 3C to maintain safe temperatures.

How does cycle life trade off against discharge rate across the 20Ah, 35Ah, and 50Ah models in the ATOMFAIR High-Power Long-Duration Battery Series?

The 50Ah model delivers the longest cycle life (≥2000 cycles at 80% SOH) but a maximum discharge rate of 3C, while the 35Ah model offers a higher 5C discharge rate with ≥1200 cycles. The 20Ah model provides ≥800 cycles at 3C discharge. This trade-off allows engineers to prioritize either extended lifespan or peak power output depending on application demands.

What are the critical voltage and temperature constraints for integrating these semi-solid electrolyte pouch cells into a battery pack?

Operating voltage ranges vary by model: 2.7–4.25V (20Ah), 2.75–4.2V (35Ah), and 2.5–4.3V (50Ah). Discharge temperature ranges are –20°C to +55°C (20Ah), –20°C to +65°C (35Ah), and –20°C to +60°C (50Ah). A BMS with overcurrent, short-circuit, and temperature protection is mandatory, and high-rate discharge may require active thermal management.

What special handling, storage, and pre-conditioning steps are required for these semi-solid electrolyte cells?

Cells are shipped in moisture-barrier vacuum-sealed aluminum foil bags inside anti-static cartons. Before first use, pre-condition at 25°C. Avoid sustained temperatures above the recommended limits. Always use a BMS with protection features. For volume orders, custom packaging is available to maintain cell integrity during storage and transport.

The ATOMFAIR High-Power Long-Duration Battery Series, available in 20Ah, 35Ah, and 50Ah capacities, leverages semi-solid electrolyte technology to deliver high discharge rates up to 5C and cycle life up to 2000 cycles at 80% SOH, making it suitable for demanding EV and industrial applications. However, the pouch cell format requires careful handling and integration with a BMS, and high-rate discharge may necessitate active thermal management.

Positive

  • High discharge rate capability: The 35Ah model supports up to 5C maximum discharge rate, enabling high power output for demanding applications such as electric motorcycles and drones.
  • Extended cycle life at 80% SOH: The 50Ah model achieves ≥2000 cycles at 80% state of health, reducing total cost of ownership in long-duration energy storage and EV applications.

Trade-offs

  • Requires BMS for safe operation: The cells must be used with a battery management system providing overcurrent, short-circuit, and temperature protection to prevent damage or safety hazards.
  • Active thermal management may be needed: High-rate discharge can generate significant heat, and the product notice indicates that active thermal management may be required to maintain performance and safety.
