Unveiling multifunctional synthetic boundaries for enhanced mechanical and electrochemical performance in densified thick composite electrodes.

ABSTRACT: High energy density lithium-ion batteries are essential for sustainable energy solutions, as they reduce reliance on fossil fuels and lower greenhouse gas emissions. Increasing electrode thickness is an effective strategy to raise energy density at the device level, but it poses inherent scientific challenges. Thick electrodes typically require a highly porous structure (over 40% porosity) to maintain sufficient charge transport. Such porosity sharply lowers volumetric energy density, limiting use in space-constrained applications. Conversely, direct densification of thick electrodes intensifies charge diffusion limitations and exacerbates mechanochemical degradation. To overcome these trade-offs, we explore a geology-inspired, transient liquid-assisted densification process that produces
