ABSTRACT Sodium‐layered oxides are a promising category of cathodes for sodium‐ion batteries with high energy densities. The solid‐state method is the typical approach to synthesizing these because its simple procedure and low cost. Although reaction conditions have usually been understated, effect reagents has often overlooked. Thus, fundamental insight into chemical required perform well. Here we report in situ structural electrochemical methods studying using different reagents. materials composite structure containing layered NaMnO 2 Li MnO 3 components, where oxygen anionic redox can be triggered at voltage by forming Na–O–Li configurations. samples synthesized via MnCO ‐based precursors form phase evaluated temperature better than those through precursors. This work demonstrates that also impact performance sodium‐layered oxides, which provides new developing high‐energy cathode material.

Recrystallization-Driven Quasi-Spherical Prussian Blue Analogs with High Tap Density and Crystallinity for Sodium-Ion Batteries

ACS Energy Letters, Journal Year: 2025, Volume and Issue: unknown, P. 1751 - 1761

Published: March 17, 2025

Prussian blue analogs (PBAs) are widely applicable as cathode materials due to their straightforward synthesis procedures, low cost, and considerable theoretical capacity. However, structural defects tap density pose substantial challenges commercial application. Herein, we propose a recrystallization-driven strategy synthesize monoclinic binary hexacyanoferrate (CFHCF) with high crystallinity remarkably of 0.992 g cm–3. Moreover, the detailed process quasi-spherical morphology evolution defect repair is systematically investigated during recrystallization. Furthermore, various in situ ex techniques employed reveal origin specific capacity mechanism. Additionally, designed CFHCF//HC pouch cell demonstrates satisfactory retention over 250 cycles successfully powers toy platform for flag raising lowering. Notably, this offers valuable insights into applications highly crystallized PBAs.

ABSTRACT Tin sulfide (SnS 2 ) is a promising anode material for sodium/potassium‐ion batteries (SIBs/PIBs) due to its large interlayer spacing and high theoretical capacity. However, application hindered by sluggish kinetics, volume expansion, low conductivity. In this work, synergistic engineering route proposed that combining environmentally friendly chlorella with sulfurized polyacrylonitrile (SPAN) achieve green doping dual‐mode confinement SnS ‐based anode. The SPAN matrix prevents agglomeration, enhances charge transfer, improves structural stability, while phosphorus (P) accelerates “solid‒solid” conversion kinetics. ‒P‒SPAN demonstrates outstanding sodium/potassium storage performance across wide temperature range (‒40°C 70°C), delivering reversible capacities, excellent rate capability, exceptional long‐term cycling stability. reliability of the as‐developed strategy in ‒P‒SPAN//NaNi 0.4 Fe 0.2 Mn O full cell also verified, which shows strong practical potential capacity long durability (241 mAh g −1 /800 cycles/0.5 A /25°C; 159 /400 /60°C; 105 /‒15°C). associated electrochemical mechanisms are elucidated through comprehensive tests, in/ex situ analyses. calculation unveil P‐doping helps enhance adsorption Na + discharge products. This work may pave way developing yet imperfect electrode materials field energy storage.
