“…The main feature of the temperature dependences of the self-diffusion coefficients is an increase in the self-diffusion activation energy with a decrease in moisture content in the entire temperature range. This effect is quite typical for the mobility of the hydrated H + cation and is due to an increase in the average strength of hydrogen bonds and steric effects [34]. It is noteworthy that there is a knee in the temperature dependence of the diffusion coefficients in the membrane held in water vapor at RH = 75% (curve 3, Fig.…”

“…As can be seen from Table 3 and Fig. 6, the conductivity and diffusion coefficient of H + ions are significantly higher than those for singly charged alkali metal cations, which is due to proton transfer according to the Grotthuss mechanism, which includes cooperative effects [34]. At maximum moisture contents, the diffusion coefficients of alkaline cations calculated from the conductivity increase in the order Li + < Na + < Cs + , which is consistent with the diffusion coefficients of cations and water molecules obtained from NMR.…”

The main patterns of the hydration of sulfo groups, the translational mobility of water molecules, alkali metal cations, and ionic conductivity in sulfocation-exchange membranes (MSC) based on polyethylene and sulfonated grafted polystyrene have been investigated using NMR and impedance spectroscopy techniques. It has been shown that at moisture contents λ < 4 (λ is the number of water molecules per sulfo group) the H + counterions in the membranes form diaquahydrogen ionsIn the temperature range below 0°C at λ < 12, water molecules retain high mobility and do not form the ice phase. Water molecules diffusion coefficients (for the H + form, the average diffusion coefficient of water molecules and acidic protons) and first for ion-exchange systems, and the diffusion coefficients of counterions Li + , Na + , and Cs + have been measured by pulsed field gradient 1 H, 7 Li, 23 Na, and 133 Cs NMR spectroscopy. In MSC membranes in contact with water, the self-diffusion coefficients of cations increase in the Li + < Na + < Cs + series. The cation conductivity values are in the same Li + < Na + < Cs + H + sequence. The cation conductivity values calculated from the self-diffusion coefficients based on the Nernst-Einstein equation are essentially higher than the experimental values.

“…The interest of researchers and manufacturers of membrane materials to the problems of creating new functional composites based on existing commercial membranes continues unabated. This is evidenced by a large number of scientific publications and patents devoted to the problem of membrane modification [1][2][3][4][5][6]. Polyaniline is one of the effective modifiers, since it possesses a set of unique electrochemical properties and is easy to synthesize [7][8][9].…”

The influence of electric field in the chemical synthesis of polyaniline on the surface of sulfonated cation-exchange membranes on their structure and properties has been investigated. By using standard contact porosimetry, it has been found that surface modification of heterogeneous membranes with polyaniline, both in static conditions and in an external electric field, does not significantly affect the distribution of water over the effective pore radii and binding energies. It has been shown that the structural heterogeneity of the ion-exchange membrane, rather than the aniline polymerization conditions, has a more significant effect on the morphology of the polyaniline layer on its surface and, hence, on the electrotransport properties. A decrease in the electrical conductivity of the composites obtained with an increase in the quantity of electricity passed during the synthesis of polyaniline on their surface has been revealed. Based on the analysis of the current-voltage characteristics of the samples and their electrical conductivity, the conditions for obtaining materials with the most pronounced asymmetry of the electrotransport properties have been determined.

“…27 This approach has led to enormous interest in the development of high shear modulus solid electrolytes. 10,13,14,16,19 Another route suggested is to increase stresses at the interface beyond the yield strength of lithium so the anode can plastically deform and planarize. 28 It may also be possible to trigger this deformation by applying an external pressure perpendicular to the cell stack greater than the yield strength of Li.…”

Solid state electrolyte systems boasting Li + conductivity of >10 mS cm −1 at room temperature have opened the potential for developing a solid state battery with power and energy densities that are competitive with conventional liquid electrolyte systems. The primary focus of this review is twofold. First, differences in Li penetration resistance in solid state systems are discussed, and kinetic limitations of the solid state interface are highlighted. Second, technological challenges associated with processing such systems in relevant form factors are elucidated, and architectures needed for cell level devices in the context of product development are reviewed. Specific research vectors that provide high value to advancing solid state batteries are outlined and discussed. Solid state battery systems are of great interest because of potential benefits in gravimetric and volumetric energy density, operable temperature range, and safety in comparison to traditional liquid electrolyte based systems. However, unresolved fundamental issues remain in the quest to fully understand the behavior of all-solid batteries, especially in the area of electrochemical interfaces.1 There are also a number of significant engineering challenges that require methodical effort to enable a tangible product. Some transitions from academic laboratories to entrepreneurial efforts attempting to overcome these challenges remain unsuccessful in efforts to bring a product to the market.2,3 Vital parameters that require robust understanding from a product development standpoint are material cost, cell lifetime and shelf life, cell energy density on a volumetric and gravimetric basis, operable capabilities for given temperature conditions, and safety. The advantage of energy density remains to be realized in solid state electrolytes (SSEs) since most studies to date utilize thick SSEs or cathodes with low active loading compared to liquid counterparts. 4,5 Furthermore, the desire to use SSEs in conjunction with Li metal anodes requires understanding and managing the morphology of Li metal plating, which can impact volumetric energy density. Operation at both higher and lower temperature compared to conventional technologies is a significant potential advantage of SSE systems. However, reports of solid state cells achieving parity with traditional systems at room temperature or any other temperature do not currently exist. The safety, specifically decreased flammability, of SSE systems is another potential advantage but requires ongoing validation and study.6 Unlike current liquid electrolyte systems, 7 the manufacturability and material component costs of SSEs have not been well characterized, and thus the value of these features will need to be weighed accordingly with any added cost. Operating lifetime of SSEs capturing intrinsic materials parameters such as voltage stability, 8 as well as catastrophic failure modes such as shorting, 9 have been briefly investigated, but in the absence of high energy density electrode formulations and appli...
