Silicon-Assisted Direct Regeneration of Spent Lithium Iron Phosphate Cathodes via Coupled Lattice and Electronic Reactivation.

Direct regeneration can preserve the value of spent lithium iron phosphate (LFP) cathodes, but conventional relithiation and thermal repair remain limited by sluggish solid-state diffusion and incomplete reconstruction of the phosphate framework. A silicon-assisted strategy is introduced to couple olivine-lattice resto...
