Special Issue Information

Dear Colleagues,

All-solid-state battery has an advantage over the liquid or gel-type batteries because of better thermal stability, non-flammability, and higher electrochemical stability. Despite extensive research towards the elaboration of solid-state battery, we still do not have a competitive candidate. So the development of a better energy storage device is still a hot topic for researchers working in the fields of materials science, physics and chemistry.

The primary focus is on Li+-ion batteries. Possibly cheaper but at the same time more challenging are Na+, Mg2+, or Cu+ batteries. Materials with new crystalline structure or successful modifications of the existing structures leading to good ionic conductivity are very important. The improvement of ionic intercalation in battery anode and cathode materials is also needed. The match between newly found electrolytes and electrodes should be tested. The research may include, but should not be limited to: synthesis description, cell preparation, crystal structure investigation, capacity measurements and theoretical calculations, charge–discharge cycling rate measurements, ionic/electronic conductivity measurements, etc.

In this Special Issue, publications about the new synthesis, structure and characterization of electrolytes, electrodes, half-cell and full battery assembly performance will be collected. Original research papers dealing with crystalline materials for Li+-ion battery and also for alternative Na+, Cu+, Ag+, and Mg2+ batteries are welcome.

In the present work, we studied the effects of substitutional Sm3+ ions on the ionic conduction properties of Li5+2xLa3Nb2−xSmxO12 (LLN-Sm) ceramics with x = 0.0—0.6. The investigated final ceramics, prepared by solid state reaction, were [...] Read more.
In the present work, we studied the effects of substitutional Sm3+ ions on the ionic conduction properties of Li5+2xLa3Nb2−xSmxO12 (LLN-Sm) ceramics with x = 0.0—0.6. The investigated final ceramics, prepared by solid state reaction, were sintered at 1000 °C for 12 h. XRD investigations showed the formation of the cubic garnet phase for all of the studied samples. The ionic conductivity was found to increase with Sm3+ content, with the highest value of 7.04 × 10−5 S/cm for the Li5+2xLa3Nb2−xSmxO12 sample compared to 7.49 × 10−6 S/cm for the pure LLN sample, both at RT. Lithium ion mobilities of LLN-Sm garnets at different temperatures were estimated. Considerable enhancement of mobility, the main factor leading to ionic conductivity improvement, was obtained for samples with Sm3+ substitutions. Relaxation processes were studied by the electric modulus, and the corresponding activation energy was found to be very similar to the ionic conduction process. Full article

The beta-Al2O3 solid electrolyte doped with Chromium was synthesized via a citrate-nitrate combustion method, which started with NaNO3, LiNO3, Cr(NO3)3·9H2O, and Al(NO3)3·9H2O as the raw materials in this paper. The thermal behavior analysis, structure, and ionic conductivity of the beta-Al2O3 solid electrolyte were studied by the thermogravimetry/differential scanning calorimetry (TG/DSC), X-ray diffraction (XRD), scanning electron microscopy (SEM), and electrochemical impedance spectroscopy (EIS). Meanwhile, the relative density and bending strength of the samples were also measured. The results showed that with the appropriate Chromium doping, the calcining temperature of the precursor powders was only 1100 °C, the β″-Al2O3 phase content, bending strength, relative density, and ionic conductivity were all improved with a compact and uniform cross section micrograph. The optimized sample contained 94% of β″-Al2O3 phase and exhibited a relative density up to 98.13% of the theoretical density. In addition, it showed a good bending strength (215 MPa) and a satisficed ionic conductivity (0.110 S cm−1 at 350 °C). Full article

The ionic transport and the mechanical properties in solids are intimately related. However, few studies have been done to elucidate the background of that relation. With the objective to fill this gap and gain further understanding on the fundamental properties of ion conducting materials, we are studying systematically the mechanical properties of different materials. In the present study, after showing briefly our previous results obtained in crystalline materials, results regarding the relation between ionic conduction and mechanical properties in superionic glasses is presented. All these results indicate the intimate relation between the mechanical and ionic conduction. The results also indicate that the Grüneisen parameter and the Anderson–Grüneisen parameter of ionic conductors exhibit large temperature dependence and increase with temperature. Full article
