The cathode materials work as the host framework for both Li+ diffusion and electron transport in Li-ion batteries. property is always research focus, while less studied. Herein, we propose a unique strategy to elevate rate performance through promoting surface electric conductivity. Specifically, disordered rock-salt phase was coherently constructed at of LiCoO2 , conductivity by over one magnitude. It increased effective voltage (Veff ) imposed bulk, thus driving more extraction/insertion...
Abstract LiCoO 2 (LCO) is the most successful cathode material for commercial lithium‐ion batteries. Cycling LCO to high potentials up 4.5 V or even 4.6 can significantly elevate capacity but cause structural degradation due serious surface side reaction between highly oxidized Co 4+ and O − species with organic electrolytes. To tackle this concern, a new strategy, constructing cation anion dual gradients at of (DG‐LCO), proposed. Specifically, electrochemically inactive are selected...
Abstract As one of the most promising cathodes for Li‐ion batteries, Li‐rich layered oxides suffer from low Coulombic efficiency, severe capacity fading, and voltage decay, which are related to aggregated Li@Mn 6 superstructure units. Herein, a Co‐free oxide Li[Li 1/4 Mn 1/2 Ni 1/6 Al 1/12 ]O 2 through substitution Co in , is designed. Combining average structural refinement with detailed local structural/chemical analysis, it found that introduced ions occupy sites units, further induces...
Single-crystalline Ni-rich layered oxides are one of the most promising cathode materials for lithium-ion batteries due to their superior structural stability. However, sluggish diffusion kinetics and interfacial issues hinder practical applications. These intensify with increasing Ni content in ultrahigh-Ni regime (≥90%), significantly threatening viability single-crystalline strategy oxide cathodes. Herein, by developing a high-entropy coating strategy, we successfully constructed an...
Closed pores are widely accepted as the critical structure for hard carbon negative electrodes in sodium-ion batteries. However, lack of a clear definition and design principle closed leads to undesirable electrochemical performance electrodes. Herein, we reveal how evolution pore mouth sizes determines solvation thereby redefine pores. The precise uniform control is achieved by using molecular sieves model material. We show when inaccessible N2 but accessible CO2 probes, only portion...
Abstract Alkali metals have low potentials and high capacities, making them ideal anodes for next‐generation batteries, but they suffer major problems, including dendrite growth Coulombic efficiency (CE). Achieving uniform metal deposition having a reliable solid electrolyte interphase (SEI) are the basic requirements overcoming these problems. Here, general remedy is reported various alkali‐metal by supramolecularization of cations with crown ethers that follows size‐matching rule. The...
Constructing a stable cathode-electrolyte-interphase (CEI) on cathode surface constitutes the foundation of realizing high-voltage Li-ion batteries, yet its formation, highly heterogeneous process involving irreversible reactions between electrolyte components and materials, remains poorly understood. Herein, combining multiple in situ/operando interfacial characterization techniques, we establish correlation structure interphasial chemistry, reveal key role played by adsorptive behavior...
Polyvinylidene fluoride (PVDF), as the commercial cathode binder for lithium‐ion batteries, presents several practical challenges, including insufficient conductivity, weak adhesion to active materials, and use of toxic N‐methylpyrrolidone slurry preparation. However, while most water‐soluble binders can address aforementioned issues, they fail meet requirements high‐voltage cathodes. In this work, we innovatively employed a thermal pulse sintering strategy modify carboxymethyl cellulose...

Abstract Li‐rich Mn‐based layered (LMR) cathodes with anionic redox chemistry show great potential for next‐generation sustainable Li‐ion battery (LIB) applications due to the low cost and high energy density. However, asynchronous structural evolutions cycling in heterogeneous composite structure of LMR lead serious lattice strain thus fast electrochemical decay, which hinders commercialization cathodes. Here, an order–disorder coherent cathode is demonstrated that exhibits a higher average...
