“…Among various aqueous, 249, 250 organic 251 and ionic liquid based choices [252][253][254] , organic electrolytes are more promising owing to their high ionic conductivity, wide electrochemical window and good electrochemical performance. 255 The most common electrolyte formulations for SIBs include NaClO4 or NaPF6 dissolved in carbonate ester solvents, particularly EC and/or PC. [256][257][258][259] Various organic electrolytes for SIBs with hardcarbon electrodes have been investigated.…”

Name., 2013, 00, 1-3 | 1 Electrolyte is a key component of electrochemical energy storage (EES) devices and its properties greatly affect the energy capacity, rate performance, cyclability and safety of all EES devices. This article offers a critical review of recent progresses and challenges in electrolyte research and development particularly for supercapacitors and supercapatteries, recharegable batteries (such as lithium-ion and sodium-ion batteries), and redox flow batteries (including fuel cells in a broad sense). The review will focus on liquid electrolytes, particularly aqueous and organic electrolytes, ionic liquids and molten salts. Influences of electrolyte properties on the performances of different EES devices are discussed in detail.

“…[5][6][7][8] Considerable efforts are presently in progress to improve appropriate electrolyte and electrode materials for practically feasible Na-batteries. 7,9,10 Among the various types of electrolyte materials, solid electrolyte materials have attracted signicant interest compared to those of the liquid electrolytes because of the protection from leakage, volatilization, or ammability. [10][11][12] However, to create the solid electrolyte batteries, a high ionic conductivity of electrolyte materials (s Na T 10 À4 S cm À1 ) at room temperature (RT) is required.…”

Structural elucidation of NASICON (Na₃Al₂P₃O₁₂) based glass electrolyte materials: effective influence of boron and gallium

Understanding the conductivity variations induced by compositional changes in sodium super ionic conducting (NASICON) glass materials is highly relevant for applications such as solid electrolytes for sodium (Na) ion batteries. In the research reported in this paper, NASICON-based NCAP glass (Na 2.8 Ca 0.1 Al 2 P 3 O 12 ) was selected as the parent glass. The present study demonstrates the changes in the Ga nuclei) were used. The Raman spectrum revealed that the NCAP glass structure is more analogous to the AlPO 4 mesoporous glass structure. The Ga MAS-NMR spectrum suggests that gallium cations in the NCAGP glass compete with the alumina cations and occupy four (GaO 4 ), five (GaO 5 ) and six (GaO 6 ) coordinated sites. The Raman spectrum of NCAGP glass indicates that sodium cations have also been substituted by gallium cations in the NCAP glass structure. From impedance analysis, the dc conductivity of the NCAP glass ($3.13 Â 10 À8 S cm À1) is slightly decreased with the substitution of gallium ($2.27 Â 10 À8 S cm À1) but considerably decreased with the substitution of boron ($1.46 Â 10 À8 S cm À1 ). The variation in the conductivity values are described based on the structural changes of NCAP glass with the substitution of gallium and boron.

“…While Na-ion batteries currently lag behind Li-ion systems in terms of volumetric energy and power density in applications where this is not a large concern, for instance grid scale power storage, this cell may offer a viable alternative in the near future for applications where cost and safety are the key drivers. This can be seen by the recent integration of a Na-ion cell into an e-bike and the significant increase in academic interest in recent times as highlighted by Vignarooban et al [28]. In conjunction with the research being conducted on improved materials, it is imperative to understand the failure processes which occur in Na-ion cells in order to expedite commercialization opportunities.…”

Thermal runaway is a phenomenon that occurs due to self-sustaining reactions within batteries at elevated temperatures resulting in catastrophic failure. Here, the thermal runaway process is studied for a Li-ion and Na-ion pouch cells of similar energy density (10.5 Wh, 12 Wh, respectively) using accelerating rate calorimetry (ARC). Both cells were constructed with a z-fold configuration, with a standard shutdown separator in the Li-ion and a low-cost polypropylene (PP) separator in the Na-ion. Even with the shutdown separator, it is shown that the self-heating rate and rate of thermal runaway in Na-ion cells is significantly slower than that observed in Li-ion systems. The thermal runaway event initiates at a higher temperature in Na-ion cells. The effect of thermal runaway on the architecture of the cells is examined using X-ray microcomputed tomography, and scanning electron microscopy (SEM) is used to examine the failed electrodes of both cells. Finally, from examination of the respective electrodes, likely due to the carbonate solvent containing electrolyte, it is suggested that thermal runaway in Naion batteries (NIBs) occurs via a similar mechanism to that reported for Li-ion cells.
