LFP 280Ah — prismatic LFP cell for energy storage systems
Country: China · Model: LFP 280Ah
A prismatic LFP cell of 280 Ah in an aluminium case of 173.9 × 71.7 × 207.2 mm, made in two versions, for 0.5P mode and for 1P mode. Modules and racks of stationary energy storage systems (BESS) are built from such cells, where the payback period of the whole installation depends on the cell life.

Description
The cell is built on LFP (lithium iron phosphate) chemistry in a flat aluminium case, so in a module it is placed tightly next to other cells. The 0.5P version is designed for a full charge or discharge in about two hours, while the 1P version works at twice the relative current and completes a cycle in about an hour. At 25 °C the 0.5P cell withstands 6000 cycles to 80 % SOH and 8000 cycles to 70 % SOH. For the 1P these thresholds come after 5000 and 7000 cycles, so the faster mode costs about a thousand cycles of life. SOH shows the share of initial capacity that the cell still retains, so the degradation threshold directly sets the design service life of the storage system. The life figures were obtained at room temperature, so a cabinet or container with such cells needs a temperature maintenance system. The cell has passed the UN38.3 transport tests.
How to choose
The choice between 0.5P and 1P determines how quickly the storage system must deliver its energy. For shifting solar plant generation to the evening hours, when the discharge lasts two hours or longer, the 0.5P with its longer life is enough. The 1P mode is needed for covering short peak loads and fast regulation, where power decides. In the same size, 306Ah / 285Ah cells are made, which give 8000 cycles to 80 % SOH in 0.5P mode and 7000 in 1P mode.

FAQ
How do the 0.5P and 1P versions of the LFP 280Ah cell differ?
The 0.5P version is charged and discharged at a current at which a cycle lasts about two hours, the 1P works twice as fast. The price of speed is life: 5000 cycles to 80 % SOH against 6000 for the 0.5P.
How many cycles does the 280 Ah LFP cell withstand to 70 % SOH?
At 25 °C the 0.5P version completes 8000 cycles, and the 1P version completes 7000 cycles to the 70 % SOH threshold.
What are the dimensions of the 280 Ah prismatic cell?
The case measures 173.9 × 71.7 × 207.2 mm. The 306 Ah and 285 Ah cells have the same size, so a larger capacity can also be selected for this case size.
Is the LFP 280Ah cell certified to UN38.3?
Yes, the cell has UN38.3 certification, without which lithium batteries are not transported by air, sea or road.
