Synergistically Boosted Na Migration and Deep Desodiation Stability of NASICON Cathode via High Entropy Regulation.

Mn-containing sodium superionic conductor (NASICON) compounds have shown considerable potential as cathode for sodium-ion batteries (SIBs) owing to higher working voltage (V/V: 3.9 V), lower cost, and lower toxicity compared to full vanadium-based NASICON NaV(PO). Taking NaVMn(PO) (NVMP) as an example, its practical application is still restricted by poor electronic conductivity, sluggish intrinsic Na diffusion, and poor high-voltage stability.

Contributions of Both the Eastman Entropy of Transfer and Electric Double Layer to the Electromotive Force of Ionic Thermoelectric Supercapacitors.

Recently, ionic thermoelectric supercapacitors have gained attention because of their high open circuit voltages, even for ions that are redox inactive. As a source of open circuit voltage (electromotive force), an asymmetry in electric double layers developed by the adsorption of ions at the electrode surfaces kept at different temperatures has previously been proposed. As another source, the Eastman entropy of transfer, which is related to the Soret coefficient, has been considered.

Intermolecular interaction mechanism for ionic liquids based on quaternary phosphonium cations with different symmetries using dielectric and spectroscopic analyses.

This study focuses on two types of phosphonium cation-based ionic liquids (P-ILs) with different alkyl chains: triethylalkylphosphonium (P222R) and tributylalkylphosphonium (P444R) cations. Broadband dielectric spectroscopy showed that the translational motion of the ions accelerated with an increasing number of alkyl chains by coupling with their rotational motion in both P-ILs. Raman spectroscopy revealed that P222R cations, despite dielectric similarities to P444R cations, can form all-trans conformations and cation-rich nanodomains because they have a relatively polar, short alkyl chain moiety with a central P atom and less-polar alkyl chains than those of P444R cations.
