Enhanced Stability of Sodium‐Ion Batteries by Controlling the Synthesis Process of Binary Metal Sulfides

Small, Год журнала: 2025, Номер unknown

Опубликована: Март 27, 2025

Abstract Binary metal sulfides hold significant promise as anode materials for advanced sodium‐ion batteries (SIBs), but their application is often limited by rapid capacity degradation and slow reaction kinetics. While carbon composites are frequently used to address these issues, the influence of sequence carbonization sulfidation on performance has been largely overlooked. To bridge this gap, Co‐Sn synthesized through various processes examine impact synthesis methods material properties. Among these, one‐step CSS‐C1 exhibits enhanced kinetics excellent stability. It delivers a 220.4 mAh g −1 at an ultra‐high current density 20 A maintained 389 over 2300 cycles 10 . When assembled into full‐cell devices (CSS‐C1||Na 3 V 2 (PO 4 ) ), it demonstrates stable retention 900 cycles, establishing highly efficient SIBs.

Synthesis of mesoporous layered iron oxide/rGO composites for stable sodium- and lithium-ion batteries

Next Materials, Год журнала: 2024, Номер 3, С. 100150 - 100150

Iron oxides, such as FeOOH, Fe2O3, and Fe3O4, are promising materials for sodium-ion (NIBs) lithium-ion (LIBs) batteries. However, the preparation of stable iron oxides NIBs LIBs usually involves intricate routes. In this work, we develop simple approaches synthesis mesoporous layered oxide (FeOOH, or Fe3O4)/reduced graphene (rGO) composites LIBs. The first involve rod-like-FeOOH/graphene (GO) sheets via hydrolysis electrostatic attraction. Rod-like FeOOH flattens GO, which facilitates layered-assembly. Two reduction-induced self-assembly methods, i.e., hydrazine-assisted reduction heat treatment can then be employed to prepare FeOOH/rGO Fe2O3/rGO, respectively, from flat FeOOH/GO sheets. Further thermal enables formation Fe3O4/rGO. All these possess mesoporosity. mesopores provide preserved void spaces volume expansion during sodiation lithiation. rGO framework serves a conductive medium transport electrons. As result, exhibit cyclability both sodium lithium storage. Notably, composite exhibits an impressive ability withstand ∼1000 cycles without experiencing significant capacity decay

Facile Fabrication of an SnS_x‐SnO₂‐Decorated Cobalt Sulfide Film as an Effective Counter Electrode for Dye‐Sensitized Solar Cells

ChemistrySelect, Год журнала: 2024, Номер 9(12)

Опубликована: Март 22, 2024

Abstract Metal sulfide stands out as one of the novel and promising platinum‐free counter electrode (CE) materials for dye‐sensitized solar cells (DSSCs). In this work, SnS x ‐SnO 2 ‐decorated CoS films were designed synthesized by a low‐temperature fabrication process. The small clusters nanoparticles create large amount catalytic active sites, resulting in superior electrocatalytic activity triiodide reduction. DSSC with film has achieved an impressive power conversion efficiency 4.57 %, which is close to platinum CE (4.82 %). Furthermore, regarding attenuation photovoltaic performance film, negligible change was observed after prolonged storage under ambient condition five days. Therefore, it worthwhile expect explorations fabricate technique synthesizing cost‐effective metal long‐term stability DSSCs.
