Lithium iron phosphate (LFP) cathodes are promising materials for energy storage device applications due to their thermal stability, chemical robustness, cost‐effectiveness, and long lifespan. However, low electronic ionic conductivity, as well challenges in achieving high packing density thick electrodes, limit practical implementation. In this study, a gradient porosity LFP electrode with areal capacity of 6.3 mAh cm − 2 an 2.5 g cc −1 is proposed. electrodes porosity, binder migration mitigated, ensuring uniform distribution that enhances Li‐ion kinetics adhesion strength between the aluminum current collector. Furthermore, by employing particle short charge carrier pathways bottom layer tap top layer, facile electron transfer easier processing can be achieved. The resulting −2 exhibits excellent cycle stability over 100 cycles full‐cell operation. These findings provide valuable insight into scalable strategies high‐energy‐density, cost‐effective LFP‐based batteries.
