A Thermally Robust Biopolymeric Separator Conveys K⁺ Transport and Interfacial Chemistry for Longevous Potassium Metal Batteries

ACS Nano, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 15, 2025

Potassium metal batteries (KMBs) hold promise for stationary energy storage with certain cost and resource merits. Nevertheless, their practicability is greatly handicapped by dendrite-related anodes, the target design of specialized separators to boost anode safety in its nascent stage. Here, we develop a thermally robust biopolymeric separator customized via solvent-exchange amino-siloxane decoration strategy render durable safe KMBs. Through experimental investigation theoretical computation, reveal that optimized porosity surface functionalization could manage ion transport interfacial chemistry, thereby enabling efficient K+ diffusion favorable solid electrolyte interphase achieve prolonged cycling stability (over 3000 h). The thus-assembled full cell retains 80% initial capacity after 400 cycles at 0.5 A g–1. heat-proof property designed further demonstrated. Our separator, affording multifunctional features, provides an appealing solution circumvent instability issues associated potassium batteries.

Sodium-Rich Prussian Blue Analogs Synthesized with Reducing Sodium Salt for Enhanced Rate and Cycling Stability Sodium-Ion Storage

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 23, 2025

Prussian blue analogs (PBAs) as cathode material for sodium-ion batteries have attracted widespread attention due to their affordability, simple synthesis, and high theoretical capacity. Nevertheless, the oxidation of Fe2+ sodium loss lead poor electrochemical properties which restrict practical use PBAs. Herein, a coprecipitation approach based on salt-reduction-assisted synthesis was proposed construct high-sodium The bisulfite (NaHSO3) not only effectively inhibits but also increases mole ratio Na+ in resulting products. optimized sample exhibits excellent specific capacity (131.1 mAh g-1 at 0.1C), rate performance (103.9 10C), good cyclic (94.8% retention after 200 cycles). Experimental results reveal that synthesized with possesses improved diffusion kinetics stable crystal structure. In this study, scalable method is introduced PBAs further applications.

Improving the Electrochemical Properties of SiO_x Anode for High-Performance Lithium-Ion Batteries by Magnesiothermic Reduction and Prelithiation

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 27, 2025

For lithium-ion batteries, silicon monoxide is a potential anode material, but its application limited by relatively large irreversible capacity loss, which leads to low initial Coulombic efficiency (ICE). In this study, we conduct two-step reaction for the formation of oxide-based materials, including magnesiothermic reduction SiOx with Mg, followed solid-state lithiation oxide Li2CO3. Our results demonstrate that Mg can reduce SiO2 Si and form MgSiO3, while Li2CO3 reacts Li2Si2O5. MgSiO3 Li2Si2O5 on surface effectively mitigate loss lithium ions, thus enhancing ICE SiOx. The resulting SiOx-Mg-Li2CO3-C nanostructure has an up 91.1% stable cycle performance. After 100 cycles at 0.5 C, still 894.5 mAh g-1, retention rate 87.9%. A full battery commercial LiNi0.8Mn0.1Co0.1O2 (NCM811) as cathode was assembled test practical applicability. cell exhibits discharge 91.4 g-1 after 1 79.9%.
