Single-atom catalysts have been paid more attention to improving sluggish reaction kinetics and anchoring polysulfide for lithium-sulfur (Li-S) batteries. It has demonstrated that d-block single-atom elements in the fourth period can chemically interact with local environment, leading effective adsorption catalytic activity toward lithium polysulfides. Enlightened by theoretical screening, first time, we design novel Nb improved sulfur immobilization catalyzation. Calculations reveal Nb-N4...
Single atom tailored metal nanoparticles represent a new type of catalysts. Herein, we demonstrate single atom-cavity coupling strategy to regulate performance nano-catalysts. Selective atomic layer deposition (ALD) was conducted deposit Ru atoms on the surface concavities PtNi (Ru-ca-PtNi). Ru-ca-PtNi exhibits record-high activity for methanol oxidation reaction (MOR) with 2.01 A mg-1Pt . Also, showcases significant durability only 16 % loss.

Owing to high ionic conductivity and mechanical strength, poly(vinylidene fluoride) (PVDF) electrolytes have attracted increasing attention for solid-state lithium batteries, but highly reactive residual solvents severely plague cycling stability. Herein, we report a free-solvent-capturing strategy triggered by reinforced ion-dipole interactions between Li+ solvent molecules. Lithium difluoro(oxalato)borate (LiDFOB) salt additive with electron-withdrawing capability serves as redistributor...
Polyethylene oxide (PEO) based electrolytes critically govern the security and energy density of solid-state batteries, but typically suffer from poor oxidation resistance at high voltages, which limits batteries. Here, we report a Lewis-acid coordinated strategy to significantly improve cyclic stability 4.8 V-class PEO-based battery. The introduced Mg
Abstract The interfacial stability between sulfide solid‐state electrolytes (SSEs) and high voltage Ni‐rich oxide cathodes is critical to the electrochemical performances of all‐solid‐state batteries (ASSBs), yet it challenging solve interface issues by surface coating modification.

Abstract The complicated interfacial problems of poly(ethylene oxide) (PEO)‐based solid polymer electrolytes (SPEs) at high voltages severely hinder its practical applications for high‐energy‐density all‐solid‐state lithium batteries (ASSLBs). Herein, the failure mechanisms ASSLBs with LiNi 0.6 Co 0.2 Mn O 2 (NCM)‐PEO are studied. It is found that after charge generates a sharp drop 0.62 V cut‐off voltage 4.30 V, and induce resistance due to forming an uneven thick cathode electrolyte...
All-solid-state batteries (ASSBs) have attracted considerable attention due to their theoretically high energy density and safety. However, maintaining intimate interfacial contact at low external pressures remains a challenge, limiting large-scale practical applications. Here, bottom-up design of all-solid-state electrodes is proposed by minimizing internal stress variation maintain transport pressures. Theoretical calculations synchrotron X-ray techniques reveal that the surface-to-bulk...
Solid-state Li-O 2 batteries (SSLOBs) have attracted considerable attention because of their high energy density and superior safety. However, sluggish kinetics severely impeded practical application. Despite efforts to design highly efficient catalysts, oxygen reaction evolution at gas-solid interfaces fast transport pathways in solid-state electrodes remain challenging. Here, we develop a dual electronic-ionic microenvironment substantially enhance electrolysis batteries. By designing...
Superparamagnetic iron oxide nanoparticles (SPION) are potential drug carriers and a magnetic resonance imaging (MRI) contrast agent for cancer therapy diagnosis.
