Unlike other Li-ion batteries, LFP batteries have better storage capacity and are cheaper to manufacture, given the rich natural deposits of iron phosphate. There are three main types of Li-ion batteries with various distinctive cell shapes and types. There are three main types of Li-ion batteries with various distinctive cell shapes and types. The most common categories employed in LFP batteries are cylindrical cells. Regardless of the dominant position the cylindrical cells take in the industry for now, prismatic LFP cells have also been taking over the industry share aggressively in recent years, and for some good reasons!

So, let us have a quick look at these amazing cells.

What Are Prismatic LFP Cells?

The prismatic LFP cells are named from the casings in which the cells are packed, which are rectangular. As the rectangular setting allows more space, a regular arrangement of LFP cells can be achieved. A very efficient packing of cells on top of each other allows the lifepo4 battery cell setting to be more efficient in terms of energy supply, durability, and cost.

How Did Prismatic LFP Cells Come into Being in the First Place?

Lithium iron phosphate is naturally available and is mined easily as per the abundance of the material. In 1996 LiFePO4 was identified as a cathode material. The stability, safety, duration and non-toxicity of the material were a no-brainer when deciding on utilizing it in Li-ion batteries. The thermal stability, electrochemical performance, and specific capacity made the prismatic LFP cell a specific option to use in place of other Li-ion cells.

How Long Do Prismatic LFP Cells Last

Prismatic cells are considerably larger in size and thus have a larger capacity than cylindrical cells. While lithium iron phosphate batteries are known for their long cycle life, the longevity of a battery is not solely determined by the type of battery cell. However, the lifespan of a battery depends on several factors, including battery chemistry, usage patterns, charging/discharging conditions, and environmental factors.

Prismatic cells can have a larger surface area and volume relative to their size compared to cylindrical cells, which can allow for a larger energy storage capacity. But it doesn’t mean the shape of the cell alone determines the energy density (energy stored per unit volume) and gravimetric energy density (energy stored per unit weight) of a battery cell, as the specific battery chemistry and cell design also contribute to its density.

LFP batteries have been tested at 25°C ± 2°C @ 0.5C/0.5C for over 6,000 cycles while retaining more than 80% of the original battery capacity, four times that of traditional Lead-acid battery [1].

What Are the Benefits of Prismatic LFP Cells

1.More capacity

The prismatic LFP cells are larger and hence can provide a remarkable battery capacity. The larger cells provide an adequate arrangement within the prismatic casing, saving space.

2.Higher Stability

Compared to other cell types and arrangements, prismatic cells require fewer cells to achieve their rated capacity. This results in a lower number of welded joints, which can improve reliability and reduce manufacturing complexity. Additionally, prismatic cells use lamination technology, which further reduces the number of cells required and improves energy management. This feature can help maintain a consistent energy utilization rate and improve overall battery performance.

3.Light weight

The shell of the LFP prismatic cell is usually made of aluminum or stainless steel, both of which are lightweight, proving to be a great asset for applications that require portability.

Why Are Prismatic LFP Cells Popular

As discussed above, the increasing demand for LFP prismatic cells includes larger capacity, efficient work, and lower risk. They are cost-effective, and safer to use with longer battery life.
