Prismatic cells

The super cell is the 280Ah LFP prismatic cell which is designed with unique structure of one-tab, that the taps stand out of the two ends of the cell.  Because the entire empty foil area is full of tabs, it can withstand larger current and the cell C-rate performance is very good. Besides,the temperature rise is obviously lower than common LFP primatic cells .

LFP Prismatic Cells are lithium iron phosphate battery cells designed with rigid aluminum or steel casing, offering exceptional safety, structural stability, and long-term reliability. LFP (LiFePO4) chemistry is widely recognized as one of the safest lithium battery technologies, making prismatic LFP cells the preferred choice for large-scale energy storage systems, electric vehicles, and industrial power applications.

As a professional LFP Prismatic Cells  supplier, we provide high-quality lithium battery cells that deliver stable performance, long service life, and excellent consistency for battery pack integration.

With the advantage of simple arrangement,convenient maintenance and the higher space utilization rate, it can be very flexibly suitable for various types  of customers and application scenarios.

Core product advantages:

Compared to cylindrical batteries and pouch batteries, our square batteries possess four core competitive advantages, creating practical value for your end products:

1. Robust structure, outstanding safety performance

The battery is encapsulated with a high-strength aluminum alloy shell, which has strong resistance to impact and vibration, effectively preventing external mechanical damage; it is also equipped with an explosion-proof valve design, which can automatically release pressure when the internal pressure of the battery is abnormal, preventing thermal runaway risks at the source. The product has passed multiple rigorous tests such as overcharge, compression, puncture, and fire, meeting automotive-grade (IATF16949), industrial-grade high safety standards, and is suitable for stable operation under complex conditions.

2. Standardized design, higher integration efficiency

The size of the battery cell and the height of the interface are standardized, allowing for direct combination of series and parallel to form a battery pack without the need for additional complex fixing brackets and buffering structures, significantly reducing the difficulty and cost of battery pack integration; at the same time, the consistency of standardized battery cells is easier to control, which can effectively improve the overall cycle life and charging and discharging efficiency of the battery pack, especially suitable for large-scale energy storage and new energy vehicle batch application scenarios.

3. Balanced energy density and rate performance

Our square batteries can achieve an energy density of 250-300Wh/kg, supporting high-rate discharging ranging from 5C to 10C, which can meet the high current requirements of acceleration and climbing in new energy vehicles, as well as the fast charging and discharging scenarios of energy storage systems; the internal resistance of the battery cell is as low as ≤30mΩ, with low heat generation during charging and discharging, and a cycle life of over 1500 times (remaining capacity ≥80%), balancing both range and durability.

4. Strong temperature adaptability, covering all scenarios

The working temperature range of the battery cell is wide, from -30℃ to 60℃. In low-temperature environments, the capacity retention rate is ≥70%, and in high-temperature environments, the cycle stability does not decline. It can meet the power supply requirements of energy storage stations in cold regions, high-temperature industrial equipment, and outdoor construction machinery and other special scenarios.

Our LFP prismatic cells are designed to meet demanding industrial requirements, ensuring safety, reliability, and long-term performance.

Battery Module Compression and Structural Design

Prismatic LFP cells may expand slightly during cycling because of changes inside the electrode structure. Battery module design should therefore include appropriate support and controlled compression.

Insufficient support may allow excessive cell movement or swelling. Excessive compression can also affect cell performance and mechanical safety. The correct compression force should follow the cell manufacturer’s module-design recommendations.

Important structural considerations include:

• End plates with sufficient mechanical strength

• Tie rods, frames or enclosure structures

• Uniform pressure across the cell surface

• Electrical insulation between cells

• Expansion allowance throughout service life

• Protection against vibration and shock

• Cell-spacing control

• Safe clearance around terminals and safety vents

For vehicle, construction machinery and mobile industrial applications, vibration and impact testing should be included in the validation process.

Busbar and Terminal Connection Design

Large-capacity prismatic cells can carry substantial current, making terminal and busbar design a critical part of battery pack performance.

The busbar system should be designed according to:

• Maximum continuous current

• Peak current and pulse duration

• Busbar material

• Cross-sectional area

• Contact resistance

• Terminal torque

• Surface treatment

• Heat dissipation

• Insulation distance

• Vibration conditions

Copper and aluminum busbars are commonly selected according to current, weight, corrosion and manufacturing requirements. Connection surfaces should remain clean and flat, and terminal torque should follow the recommended value.

Improper terminal assembly may result in:

• High contact resistance

• Localized heating

• Voltage imbalance

• Loose connections

• Terminal damage

• Reduced battery pack efficiency

Terminal temperature should be monitored during prototype current testing.

Thermal Management for Large LFP Prismatic Cells

Although LFP chemistry offers good thermal stability, thermal management remains essential for achieving long service life and consistent battery pack performance.

The thermal system should aim to minimize both the maximum cell temperature and the temperature difference between cells.

Air Cooling

Air cooling can be suitable for lower-current battery packs, backup power and moderate ambient conditions. The enclosure should provide a controlled airflow path rather than relying on random ventilation.

Liquid Cooling

Liquid cooling may be preferred for high-energy battery racks, high ambient temperatures, frequent cycling or compact battery enclosures. Cooling plates can be positioned at the bottom or sides of the cells depending on the module structure.

Conductive Cooling

Thermally conductive pads, plates and enclosure surfaces can transfer heat from the cell to the battery structure. Material thickness and compression should remain consistent across the module.

Heating for Cold Environments

At low temperatures, charging capability can be limited. Battery systems used in cold climates may require heating films, liquid heating or controlled preheating before charging.

Temperature sensors should be placed near likely hot spots rather than only at easily accessible positions.

BMS Matching Requirements

The battery management system should be selected according to the battery configuration, current demand and application safety requirements.

Core BMS functions should include:

• Individual cell-voltage monitoring

• Charge overvoltage protection

• Discharge undervoltage protection

• Overcurrent protection

• Short-circuit protection

• High- and low-temperature protection

• Cell balancing

• State-of-charge estimation

• State-of-health estimation

• Insulation monitoring for high-voltage systems

• Communication with inverters, chargers or vehicle controllers

• Fault recording and remote diagnostics

For 280Ah and other large-capacity cells, the BMS balancing strategy is particularly important. Small differences between cells can accumulate over repeated cycles, reducing usable pack capacity.

Passive balancing may be sufficient for well-matched cells and moderate applications. Active balancing may be considered for large systems requiring higher balancing efficiency or a wider operating state-of-charge range.
