Abstract With the growing global demand for renewable energy and increasing scarcity of lithium resources, sodium‐ion batteries have received extensive attention research as a potential alternative. Among many cathode materials batteries, polyanion are favored their high operating voltage, stable cycling performance, good safety. However, low electronic conductivity density polyanionic limit large‐scale commercial applications. To overcome this challenge, various strategies been explored to improve electrochemical performance. them, fluorine doping has proven be an effective means. In study, we systematically effects trace mass substitution on structure, dynamics, electrochemistry deeply analyzed reaction mechanisms. The analysis results show that can effectively material, thus enhancing its A large amount voltage plateau density. environmental safety challenges associated with introduction should also addressed. Overall, in further optimize structure realizing wide application high‐performance making them competitive battery technology.

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.

Sodium‐ion batteries have garnered significant attention as a cost‐effective alternative to lithium‐ion due the abundance and affordability of sodium precursors. However, lack suitable electrode materials with both high capacity excellent stability continues hinder their practical viability. Herein, we couple lattice strain sulfur deficiency effects in tin monosulfide/reduced graphene oxide composite enhance storage performance. Experimental results theoretical calculations reveal that synergistic vacancies monosulfide promote rapid (de)intercalation near surface/edge material, thereby enhancing its pseudocapacitive properties. Consequently, strained defective demonstrates reversible 511.82 mAh g −1 at 1 A an outstanding rate capability 450.60 3 . This study offers effective strategy for improving performance through defect engineering.

All-solid-state lithium–sulfur (Li–S) batteries have emerged as one of the most promising alternative energy storage solutions ascribed to their potentials high density, cost-effectiveness, and enhanced safety. Herein, elastomeric polymer-in-salt electrolytes (PISEs) been developed by incorporation highly dielectric curable cyclic carbonate pendent groups into polyether backbone fabricate sulfurized polyacrylonitrile (SPAN)/Li batteries. The PISEs with an intrinsic saturation coordination sites exhibit effective inhibitions dissolution lithium polysulfides growth dendrites show favorable compatibility both SPAN cathode metal anode. robust LiF-rich interphases formed between electrodes are capable effectively passivating accommodating volume expansion, enabling all-solid-sate SPAN/PISE/Li a specific capacity ∼1300 mAh gsulfur–1 long-term cycling stability (over 4 months) at ambient temperature. This work provides strategic framework for design high-performance polymer-based all-solid-state Li–S

Solid-state lithium metal batteries (SSLMBs) suffer from stress accumulation, poor interfacial stability, and dendrite growth. A potential solution to these issues is the design of a three-dimensional nanotubular mixed ionic-electronic conductor (MIEC) as host, which induces plating/stripping inside via Coble creep. Herein, we develop novel MIEC comprising mechanically robust electrochemically stable titanium nitride (TiN) nanotube array, with an ion-conductive solid electrolyte interphase (SEI) coating on inner surface TiN host. The highly lithiophilic provides consecutive ion/electron transport channels, promoting uniform deposition nanotubes thereby maintaining exceptional stability during cycling. Consequently, SSLMBs employing this rationally designed host demonstrate remarkable electrochemical performance. This work new insights for construction advanced MIECs high-performance SSLMBs.
