Li-IP, LFP (lithium ferro-phosphate), or LiFePO4 battery, is the abbreviations of lithium iron phosphate battery, a type of lithium-ion battery using lithium iron phosphate as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. On such a basis, the LiFePO4 prismatic battery can be manufactured in a design where an insulating sheet is laid down, then a thin layer of anode material is laid down, a separator layer is applied, and a cathode material is layered on top, resembling a Swiss roll, thus gaining its name Swiss roll or jelly roll. Such a design allows higher power density and better performance.

Batteries featuring LiFePO4 prismatic cells are in high demand these days thanks to some of the unique advantages these cells offer compared to cylindrical cells. When choosing LiFePO4 prismatic cells, some may need clarification when they find there is more than one quality level of these batteries. Grade A and Grade B LiFePO4 prismatic cells, for example, may lead to several questions: how do they differ? Is Grade B necessarily worse than Grade A? In what way? Does Grade A refer to flawless prismatic cells, and is grade B the synonym for cosmetic or performance defects?

LiFePO4batteries are among the popular types of rechargeable batteries in recent years thanks to their many advantages as a reliable energy storage solution. Made using lithium-ion technology, with the addition of phosphate and iron, these batteries feature durable and stable LiFePO4prismatic cells. LiFePO4 batteries are in high demand because of their safety features, long lifespan, and excellent performance. These qualities make them suitable for a wide variety of applications. They are playing an important role in the transition towards a more sustainable energy future.
