Abstract The advancement of photo‐assisted rechargeable sodium‐metal batteries with high energy efficiency, lightweight structure, and simplified design is crucial for the growing demand in portable electronics. However, addressing intrinsic safety concerns liquid electrolytes sluggish reaction kinetics existing photoelectrochemical storage cathodes (PSCs) remains a significant challenge. In this work, functionalized light‐driven composite solid electrolyte (CSE) fillers are systematically screened, optimized PSC materials employed to construct advanced solid‐state battery (PSSMB). To further enhance mechanical properties poly(ethylene oxide) compatibility CSE, natural lignocellulose incorporated, enabling fabrication flexible PSSMBs. situ tests density functional theory calculations reveal that electric field facilitated sodium salt dissociation, reduced interfacial resistance, improved ionic conductivity (0.1 mS cm −1 ). Meanwhile, energy‐level matching maximized utilization photogenerated carriers, accelerating enhancing interface between cathode. resulting pouch‐type PSSMB demonstrates remarkable discharge capacity 117 mAh g outstanding long‐term cycling stability, retaining 89.1% its achieving an efficiency 96.8% after 300 cycles at 1 C. This study highlights versatile strategy advancing safe, high‐performance batteries.

Deciphering Interfacial Stability of Sulfide and Halide-Based Electrolytes via Operando X-ray Photoelectron Spectroscopy

Nano Letters, Год журнала: 2025, Номер unknown

Опубликована: Март 10, 2025

Combined solid electrolytes address cathode-anode compatibility in all-solid-state Li-ion batteries (ASSLBs), yet interface stability and ion transport mechanisms between different remain unclear. Herein, we investigate Li6PS5Cl (LPSC), Li3InCl6 (LIC), Li1.75ZrO0.5Cl4.75 (LZOC) composite through electrochemical analysis operando X-ray photoelectron spectroscopy. Our results reveal that the electrostatic potential difference LPSC LIC inhibits Li+ migration, leading to decomposition of into InCl3 LiCl, causing battery failure. In contrast, LZOC forms an oxygen-rich interphase with LiCoO2 (LCO), showing better interfacial stability. The promotes diffusion, maintaining even as decomposes, thereby preventing severe degradation LZOC. Therefore, LCO-LZOC cathode exhibits performance than LCO-LIC. This study elucidates basic mechanism reaction diffusion sulfide–halide emphasizes key role electrolyte ASSLBs failure pathways.

Опубликована: Апрель 25, 2025

Composite copper foil, a novel negative electrode current collector developed in recent years, can significantly enhance battery safety and energy density while also conserving metallic resources. It is found that after 9 months of long-term storage, the tensile strength composite foil decreases by 9.76%, elongation rate drops 26.32%. The internal texture shifts from highly oriented (111) plane to more random crystal orientation bonding improved. study reveals residual stress within layer provides driving force for changes microstructure; intermediate PET plays buffering absorbing role stress-release process. regulates redistribution stress, promoting alteration layer’s refinement grains.
