TL;DR: In this paper , a low-temperature (low-T) SIB based on 0.5 M NaPF6 diglyme electrolyte was proposed to accelerate diffusivity of Na+ and reduce charge transfer energy (from 461.9 to 158.6 meV).

TL;DR: Li et al. as discussed by the authors investigated the over-discharged mechanism of LiCoO2/graphite pouch cells, especially spatially resolving the morphological, surface phase, and local electronic structure of LiCO2 electrode with synchrotron-based X-ray techniques and Raman mapping, together with spectroscopy simulations, demonstrating that over-lithiation reaction is a surface effect accompanied by Co reduction and surface structure transformation to Li2CoO 2/Co3O4/CoO/Li2O-like phases.

TL;DR: In this paper , a strategy is initiated to directly address Mn dissolution and unstable interface structure, where a beneficial solid phase reaction occurs at the LNMO interface, transforming the spinel phase into two functional phases, the layered phase that provides electrochemical activity and supports charge transport, and the rock-salt like phase induced by Li/Mn exchange that can inhibit the dissolution of Mn and provide inert protection.

TL;DR: In this article , the authors investigated the interphase that forms between a high-voltage Na3V2(PO4)2F3 cathode and the electrolytes consisting of 3.0, 1.0 and 0.3 M NaClO4 in an organic carbonate solvent (47.5:47).
