Tetrahedral Lithium Stuffing in Disordered Rocksalt Cathodes for High-Power-Density and Energy-Density Batteries

Journal of the American Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 22, 2025

Li-rich cation-disordered rocksalt (DRX) materials introduce new paradigms in the design of high-capacity Li-ion battery cathode materials. However, DRX show strikingly sluggish kinetics due to random Li percolation with poor rate performance. Here, we demonstrate that stuffing into tetrahedral sites Mn-based skeleton injects a novel tetrahedron-octahedron-tetrahedron diffusion path, which acts as low-energy-barrier hub facilitate high-speed transport. Moreover, enhanced stability lattice oxygen and suppression transition metal migration preserve efficacy network during cycling. Overall, material exhibits high energy density (311 mAh g–1, 923 Wh kg–1) power (251 697 kg–1 at 1000 mA g–1). Our results highlight potential develop high-performance earth-abundant within extensive range compounds.

Direct recycling of cathode materials has attracted phenomenal attention due to its economic and eco-friendly advantages. However, existing direct technologies are difficult apply highly degraded layered as the accumulation thick rock-salt phases on their surfaces not only blocks lithiation channels but also is thermodynamically transform into phases. Here, a surface engineering-assisted upcycling strategy that reactivates lithium diffusion at using acid etching explored. Acid can selectively remove electrochemically inert while simultaneously dissociating polycrystalline structure single crystals, thereby reducing thermodynamic barrier relithiation process enhancing stability regenerated cathode. This restore capacity LiNi0.5Co0.2Mn0.3O2 from 59.7 165.4 mAh g-1, comparable commercialized ones. The exhibits excellent electrochemical with retention 80.1% 1 C after 500 cycles within 3.0-4.2 V (vs graphite) in pouch-type full cells. In addition, generality this been validated Ni-rich LiCoO2. work presents promising approach for materials.

Multifunctional Spinel Structure for Efficient Direct Recycling of Spent Layered Cathodes into Fast‐Charging Materials

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 8, 2025

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.
