Prismatic Cell

Introduced in the early 1990s, the modern prismatic cell satisfies the demand for thinner sizes. Wrapped in elegant packages resembling a box of chewing gum or a small chocolate bar, prismatic cells make optimal use of space by using the layered approach. Other designs are wound and flattened into a pseudo-prismatic jelly roll. These cells are predominantly found in mobile phones, tablets and low-profile laptops ranging from 800mAh to 4,000mAh. No universal format exists and each manufacturer designs its own.

Prismatic cells are also available in large formats. Packaged in welded aluminum housings, the cells deliver capacities of 2050Ah and are primarily used for electric powertrains in hybrid and electric vehicles. Figure 5 shows the prismatic cell.

The prismatic cell improves space utilization and allows flexible design but it can be more expensive to manufacture, less efficient in thermal management and have a shorter cycle life than the cylindrical design. Allow for some swelling.

The prismatic cell requires a firm enclosure to achieve compression. Some swelling due to gas buildup is normal, and growth allowance must be made; a 5mm (0.2) cell can grow to 8mm (0.3) after 500 cycles. Discontinue using the battery if the distortion presses against the battery compartment. Bulging batteries can damage equipment and compromise safety.

From battery university looks like this is what it is, I was confused because I have seen many on here refer to the pouch cells as prismatic:Introduced in the early 1990s, the modern prismatic cell satisfies the demand for thinner sizes.

We will now talk about one of the most important battery cells used in

producing Lithium-ion batteries – the prismatic cells.

The history of prismatic battery cells can be dated back to the early 1990s.

Today, th

ack a punch, in terms of the solutions they offer. For

example, they are used to meet the demands for lowered manufacturing

costs and reducing the size or footprints of batteries.

The presentation or structure of these cells are one of the unique

attributes. They are typically enclosed or encased in a casing that is either

made of 

 aluminum

 or steel.

The electrochemical materials are often stacked, sealed or sandwiched

into layers before they are encased in a rigid, aluminum alloy or steel

casing.

Here are some additional pieces of information to know about the

structure of prismatic battery cells:
