The “four-in-one” upgraded regeneration strategy achieved the directional regeneration of waste low-nickel polycrystalline NCM111 to the molybdenum-gradient-doped nickel-rich single crystal NCM811.
The Ni–Co–Mn synergy synergistically modulates the charge distribution of the multimetallic matrix, thereby optimizing the adsorption energetics of reaction intermediates.
This review enhances a fundamental understanding of the degradation mechanisms of Ni-based layered cathodes under fast-charging conditions from atomic to electrode scales. Design strategies for enhancing fast-charging performance are also suggested.
A defect-state Fe1−xTiO3−x-NS catalyst with high-activity {012} facets enables efficient non-oxidative conversion of methane under light by lowering C–H activation energy, suppressing methyl over-dehydrogenation, and promoting C–C coupling.
Scalable upcycling of spent NCM111 into high-performance single-crystal Ni-rich cathodes using a multifunctional, low-cost nickel salt.
