COMMERCIAL GRADE PRODUCTION

Product Overview
The ATOMFAIR® 3.2V 50Ah wide-temperature prismatic cell is engineered to deliver reliable discharge at -50°C and stable charging at -30°C, addressing the most demanding extreme-environment applications. With a 3.2 V nominal voltage, 50.0 Ah rated capacity, and an energy density of ~120 Wh/kg, this platform demonstrates exceptional capacity retention and voltage stability across a broad temperature spectrum from -50°C to 60°C. Featuring 3.0C continuous discharge capability and 1.0C standard charging, along with pulse discharge performance at 12.0C for 30 seconds, this cell ensures robust high-power delivery under extreme cold conditions. Cycle life validation confirms ≥4,000 cycles at 25°C and ≥1,000 cycles at -10°C, guaranteeing long-term operational reliability. This commercial-grade solution is ideal for outdoor surveillance, communication base stations, photovoltaic energy storage, start-stop power supplies, industrial and commercial storage, polar scientific expeditions, AGV systems, and military border defense applications where wide-temperature performance is non-negotiable.

This cell requires strict environmental controls to maintain performance and safety. It must not be disassembled, short-circuited, or exposed to temperatures outside its rated range.

  • Operating Temperature Limits: Discharge operation is limited to -50°C to 60°C and charging to -30°C to 55°C; exceeding these ranges may cause permanent damage.
  • Storage Conditions: Store cells in a cool, dry environment to avoid accelerated degradation and capacity loss.
  • Mechanical and Electrical Safety: Never disassemble, deform, short-circuit, or incinerate the cell to prevent fire or explosion hazard.
  • Protection Circuitry Requirement: Integrate appropriate cell balancing and protection circuitry in battery pack assembly to ensure safe operation.
  • Thermal Runaway Prevention: Avoid exposure to temperatures above 60°C during operation to mitigate risk of thermal runaway.

Prepare the cell for use by verifying environmental conditions and connection integrity. Follow these steps to ensure safe operation and long cycle life.

Required Equipment: Battery Management System (BMS) with balancing and protection circuitry

  1. Store the cell
    Store the cell in a cool, dry environment to prevent degradation.
  2. Verify charging temperature
    Verify that the ambient temperature is within the charging range before connecting to a charger.
  3. Connect to BMS
    Connect the cell to a battery management system with appropriate balancing and protection circuitry.
  4. Prevent physical abuse
    Avoid disassembling, deforming, short-circuiting, or incinerating the cell.

How does the cycle life of the ATOMFAIR 3.2V 50Ah wide-temperature cell vary between room temperature and low-temperature operation?

The cell delivers ≥4,000 cycles at 25°C (1.0C/1.0C) but ≥1,000 cycles at -10°C (0.33C/1C). This substantial reduction reflects the increased electrolyte resistance and lithium plating risk at sub-zero temperatures, though the cell still meets commercial requirements for cold-climate applications.

What are the charging current constraints for the ATOMFAIR 50Ah cell at sub-zero temperatures?

Below 0°C, the standard charge current is limited to 7.5A (0.15C) between -20°C and 0°C, and charging is not recommended below -30°C. From 0°C to 55°C, the standard charge current is 50.0A (1.0C). The maximum continuous charge current of 150.0A (3.0C) is only allowed at 5°C to 55°C when SOC is below 50%.

What storage and handling precautions are required for the ATOMFAIR 3.2V 50Ah prismatic cell?

Cells should be stored in a cool, dry environment, avoiding prolonged temperatures above 60°C or below -50°C during operation. The manufacturer warns against disassembly, deformation, short-circuiting, or incineration, and recommends appropriate cell balancing and protection circuitry in battery pack assembly.

The ATOMFAIR 3.2V 50Ah prismatic cell provides reliable discharge down to -50°C and charging down to -30°C with 12.0C pulse capability, making it suitable for extreme-environment stationary storage and mobile systems. However, low-temperature charging requires reduced current (0.15C below 0°C) and the cell demands external balancing and protection circuitry in pack assembly, adding system-level engineering requirements.

Positive

  • Ultra-wide temperature operation: Delivers discharge from -50°C to 60°C and stable charging from -30°C to 55°C, enabling uninterrupted performance in extreme climatic conditions without specialized thermal management.
  • High rate and pulse capability: Supports 4.0C continuous discharge at low temperatures, 3.0C at ambient, and validated 12.0C pulse for 30 seconds, providing instant high-power output for demanding applications like start-stop power supplies and AGVs.

Trade-offs

  • Charging current derating at low temp: Standard charge current is reduced to 7.5A (0.15C) from -20°C to 0°C and charging is not supported below -30°C, limiting rapid recharge in extreme cold environments.
  • System-level integration requirements: Cells require appropriate balancing circuits, protection circuitry, and controlled storage conditions (cool, dry environment) to avoid thermal stress, which adds complexity and cost for battery pack assembly.
