Abstract Direct recycling is increasingly recognized as a promising solution to alleviate the burgeoning contradiction between growing demand for lithium‐ion batteries (LIBs) and amidst resource shortages. A critical challenge in this process achieving efficient lithium compensation, which vital replenishing lost elements promoting reconstruction of degraded structures. Herein, inspired by concept “recycle waste with waste,” channel‐assisted regeneration strategy proposed that utilizes spinel materials reconstruct surface spent layered cathode, clearing blocked channels transforming them into 3D structure facilitates rapid transmission. This approach enhances replenishment exogenous salts particle lattice prevents intrinsic thermal decomposition during heat treatment due element deficiencies. The presence ion can also improve fast‐charging performance regenerated cathode material, capacity retention rate 87.9% after 500 cycles at 10 C. Additionally, its overall electrochemical significantly outperforms commercial materials. work addresses challenges direct solid‐phase offers valuable insights optimizing next‐generation LIB technologies.

Abstract The rising demand for lithium‐ion batteries (LIBs) has intensified the need efficient recycling methods to address both supply chain constraints and environmental impacts. Direct upcycling, distinguished by its ability achieve structural compositional integrity of cathode materials, gained prominence as a sustainable alternative conventional pyrometallurgical hydrometallurgical processes. However, current direct upcycling are typically limited incorporating Li and/or Ni, significantly constraining adaptability across diverse LiNi x Mn y Co z O 2 (NMCs). In this study, versatile molten salt approach is reported that expands scope enabling simultaneous incorporation Li, Mn. This methodology facilitates flexible conversion among NMC compositions, including non‐stoichiometric Co/Mn systems such degraded LiCoO (D‐LCO), 1/3 (D‐NMC111), 0.8 0.1 (D‐NMC811) surface enriched NMC111, 0.5 0.3 0.2 (NMC532), NMC811, respectively. gradient transition metal distribution in upcycled products, characterized Mn‐enriched outer layers Co/Ni‐enriched cores enhances interfacial stability cathodes, addressing critical challenges long‐term performance integrity. These results highlight potential flux advancing spent cathodes producing high‐performance materials next‐generation LIBs applications.

Abstract Recycling end‐of‐life lithium‐ion batteries (LIBs) to recover high‐value cathode materials such as LiNi x Mn y Co z O 2 (NMC) is driven by economical, geopolitical, and sustainability needs. There has been recent interest in direct recycling methods improve efficiency recovery of materials, including ionothermal, hydothermal, solid‐state, or redox mediator methods. In conjunction with process development, detailed structural characterization necessary order understand the mechanisms efficacy steps. Solid‐state nuclear magnetic resonance (NMR) spectroscopy a unique tool that can probe Li coordination, bulk surface environments, transition metal ordering recycled upcycled NMC cathodes. Here, 6,7 Li, 1 H, 19 F NMR compositional changes well impurities may form during each step utilized. During relithiation, reinsertion into lattice observed. upcycling, where goal increase Ni content NMC, incorporation Ni‐rich phases environment Surface formed processing were also identified. These studies provide valuable information for optimizing processes reach targeted composition structure enable electrochemical performance comparable better than pristine materials.
