The synergistic regulation of the electronic structures transition-metal oxide-based catalysts via oxygen vacancy defects and single-atom doping is efficient to boost their evolution reaction (OER) performance, which remains challenging due complex synthetic procedures. Herein, a facile defect-induced in situ deposition strategy developed anchor atomically dispersed Ru onto vacancy-rich cobalt oxides (Ru/Co3O4–x) based on spontaneous redox between Ru3+ ions nonstoichiometric Co3O4–x....
Abstract Potassium‐ion batteries (PIBs) have attracted increasing interest as promising alternatives to lithium‐ion (LIBs) in large‐scale electrical energy storage systems due the potential price advantages, abundant availability of potassium resources, and low standard redox potassium. However, pursuit suitable cathode materials that exhibit desirable characteristics such voltage platforms, high capacity, long cycling stability is utmost importance. Recently, layered transition‐metal oxides...
The direct recycling of cathode materials in lithium-ion batteries is important for environmental protection and resource conservation. key regeneration processes are composition replenishment atom rearrangement, both which depend on the migration diffusion atoms. However, degraded LiNi
Abstract Facing the resource and environmental pressures brought by retiring wave of lithium‐ion batteries (LIBs), direct recycling methods are considered to be next generation's solution. However, contradiction between limited battery life demand for rapidly iterating technology forces recovery paradigm shift toward “direct upcycling.” Herein, a closed‐loop upcycling strategy that converts waste current collector debris into dopants is proposed, highly inclusive eutectic molten salt system...

Abstract Platinum (Pt) remains the benchmark electrocatalyst for alkaline hydrogen evolution reaction (HER), but its industry‐scale production is severely hampered by lack of well‐designed durable Pt‐based materials that can operate at ampere‐level current densities. Herein, based on original oxide layer and parallel convex structure surface nickel foam (NF), a 3D quasi‐parallel architecture consisting dense Pt nanoparticles (NPs) immobilized oxygen vacancy‐rich NiO x heterojunctions (Pt/NiO...
Abstract Potassium‐ion batteries (PIBs) are a favorable alternative to lithium‐ion (LIBs) for the large‐scale electrochemical storage devices because of high natural abundance potassium resources. However, conventional PIB electrodes usually exhibit low actual capacities and poor cyclic stability due large radius ions (1.39 Å). In addition, reactivity metal raises serious safety concerns. These characteristics seriously inhibit practical use electrodes. Here, zinc phosphide composites...
Abstract Mn‐based layered oxide is extensively investigated as a promising cathode material for potassium‐ion batteries due to its high theoretical capacity and natural abundance of manganese. However, the Jahn–Teller distortion caused by high‐spin Mn 3+ (t 2g 3 e g 1 ) destabilizes host structure reduces cycling stability. Here, K 0.02 Na 0.55 0.70 Ni 0.25 Zn 0.05 O 2 (denoted KNMNO‐Z) reported inhibit effect reduce irreversible phase transition. Through implementation Zn‐doping strategy,...
Abstract Potassium batteries have received extensive attention as a promising grid‐level storage technology. However, the anodes in potassium using conventional carbonate‐based electrolyte systems always suffer from severe capacity deterioration, due to heterogeneous and highly swollen solid‐electrolyte interphase (SEI) layer. Herein, rigid‐flexible compact SEI consisting of rigid inner KF layer flexible crosslinked oligomeric K–B(OCH 2 CH ) n (modified KEO), is designed by tailoring...
Recycling the graphite anode is essential for both environmental protection and resource sustainability in lithium-ion batteries. Current recycling strategies emphasize closed-loop recovery but ignore potential value-added utilization. Herein, we present an upcycling strategy that converts spent into fast-charging graphite. By creating isotropic ion transport pathway on surface of utilizing fast migration channel inherent bulk's defect structure, a direct upgrade charging achieved. A...
Abstract As anodes for metal‐ion batteries, metal phosphides usually suffer from severe capacity degradation because of their huge volume expansion and unstable solid electrolyte interphase (SEI), especially potassium‐ion batteries (PIBs). To address these issues, this study proposes amorphous phosphates acting as buffer materials.
