Li-ion prismatic cells are made up of massive sheets of anodes separators and cathodes that are rolled, sandwiched, and then pressed into the housing of a hard-plastic or metallic one in cubic shape. The electrodes are also constructed by layer stacking instead of jelly rolling.
The electrodes and separator sheets in the custom prismatic lithium cell which are near to the corners of the container may encounter more pressure. This could cause damage to the electrode and result in a dispersion of electrolytes.

When combining prismatic lithium cells in packs, the box-like shape allows for optimal utilization of the space available. However, this ideal space is at the cost of difficult thermal management. This is due to the fact that there are no spaces between cells, as there are in a cluster with cylindrical cells.
The Prismatic cell is manufactured with capacities that range from a few amp-hours for mobile phones and laptops to hundreds of amp-hours specifically designed for use in EV applications.
The prismatic cell is more costly to produce. In addition, they increase in size with usage.
Although they experience less excess swelling than pouch cells do.
These are the usage and benefits of prismatic lithium ion batteries and these batteries are currently utilized in a variety of electronic devices.
