Thick LFP electrodes are unavoidable due to the intrinsically low capacity and density of LFP, yet conventional wet processes suffer from severe binder migration and compositional inhomogeneity. Through dry electrode processing, this study proposes design guidelines for optimized high-energy-density LiFePO₄ (LFP) cathodes for both single-crystal(SC) and polycrystalline(PC) materials by quantitatively analyzing each processing step.
