Potential applications of sodium-ion batteries in grid-scale energy storage, portable electronics and electric vehicles have revitalized research interest in these batteries. However, the performance of sodium-ion electrode materials has not been competitive with that of lithium-ion electrode materials. Here we present sodium manganese hexacyanomanganate (Na2MnII[MnII(CN)6]), an open-framework ...

A surface plasmon resonance (SPR) sodium ion sensor using an ion optode membrane film was experimentally and theoretically described based on an absorption-based SPR principle proposed in our previous article (Kurihara, K; Suzuki, K. AnaL Chem. 2002, 74, 696-701). The sodium ion concentrations from 10(-6) to 10(-1) have been successfully determined not only by the resonance angle diagnosis of t...

kashan aquifer is adjacent to salt lake. because of this adjacency, the saline water of the lake has moved to the aquifer. in this study groundwater quality of the aquifer was simulated using artificial neural network (ann) model. for this purpose, the dominant ion of water was first determined by piper diagram. results showed that the sodium chloride is the dominant ion of water and so it was ...

Bacterial flagella contain membrane-embedded stators, Mot complexes, that harness the energy of either transmembrane proton or sodium ion gradients to power motility. Use of sodium ion gradients is associated with elevated pH and sodium concentrations. The Mot complexes studied to date contain channels that use either protons or sodium ions, with some bacteria having only one type and others ha...

Sodium-Ion Batteries High-voltage P2-type cathodes suffer from sluggish reaction kinetics. In article number 2100123 by Peiyu Hou, Haitao Huang, and co-workers, hierarchically assembled nanoplates with highly exposed {010} facets are designed to achieve high power density sodium-ion batteries.

the interaction between sodium and calcium, magnesium and calcium and the combined effect of sodium, magnesium and calcium was observed on the growth and ion uptake of hippophae rhamnoides l. the results demonstrated that an addition of sodium with calcium, (set a, na 2.5 + ca 5 mm) showed prominent increase in fresh weight of roots and shoots. the dry weight (average) of roots decreased and th...

Sodium-Ion Batteries Cathode materials are decisive for the development of sodium-ion batteries (SIBs). In article number 2110108, Xing-Long Wu and co-workers present a high-entropy Na3V2(PO4)2F3-based cathode advanced SIBs. The effect endows this material with lowered Na+ migration barrier enhanced electronic conductivity, which jointly promote charge transport sodium-storage ability in phosph...

Quasi-Solid-State Sodium-Ion Capacitors In article number 2300068, Fangyuan Hu and co-workers develop a novel gel polymer electrolyte that containing 3-(1-vinyl-3-imidazolio) propanesulfonate zwitterion, which shows the dual effects of fast desolvation near interface rapid ion transport through to increase kinetics anions cations, enabling high energy density stable cycling performance for sodi...

Sodium-ion battery is a potential application system for large-scale energy storage due to the advantage of higher nature abundance and lower production cost sodium-based materials. However, there exist inevitably safety problems such as flammability use same type organic liquid electrolyte with lithium-ion battery. Gel polymer electrolytes are being considered an effective solution replace con...
