“…If further development of Na‐ion conductive sulfide SEs is to be carried out and higher ionic conductivity is to be achieved, a new era of all‐solid‐state Na batteries could begin 73. The exploration of Mg‐conducting sulfide materials, such as MgS ⋅ P 2 S 5 ⋅ MgI 2 glass,74 is also in line with the aforementioned research trends for new generation batteries 73,75…”

For all‐solution‐processed (ASP) devices, transparent conducting oxide (TCO) nanocrystal (NC) inks are anticipated as the next‐generation electrodes to replace both those synthesized by sputtering techniques and those consisting of rare metals, but a universal and one‐pot method to prepare these inks is still lacking. A universal one‐pot strategy is now described; through simply heating a mixture of metal–organic precursors a wide range of TCO NC inks, which can be assembled into high‐performance electrodes for use in ASP optoelectronics, were synthesized. This method can be used for various oxide NC inks with yields as high as 10 g. The formed NCs are of high crystallinity, uniform morphology, monodispersity, and high ink stability and feature effective doping. Therefore, the inks can be readily assembled into films with a surface roughness of 1.6 nm. Typically, a sheet resistance of 110 Ω sq−1 can be achieved with a transmittance of 88 %, which is the best performance for TCO NC ink‐based electrodes described to date. These electrodes can thus drive a polymer light‐emitting diode (PLED) with a luminance of 2200 cd m−2 at 100 mA cm−2.

“…This can address the leakage and combustion of liquid electrolytes, which is a grave limitation of lithium-ion batteries. For decades, the development of solid electrolytes with Mg-ion conductivity based on ceramics and glass has been the subject of extensive research (Ikeda et al, 1987;Imanaka et al, 2000;Imanaka et al, 2001;Kawamura et al, 2001;Higashi et al, 2014;Yamanaka et al, 2014;Adamu and Kale 2016). It has been reported that the Mg-ions in these inorganic solid electrolytes diffuse through the conduction paths in these materials.…”

Molecular crystals have attracted increasing attention as a candidate for innovative solid electrolytes with solid-state Mg-ion conductivity. In this work, we synthesized a novel Mg-ion-conducting molecular crystal, Mg{N(SO2CF3)2}2(CH3OC5H9)2 (Mg(TFSA)2(CPME)2), composed of Mg bis(trifluoromethanesulfonyl)amide (Mg(TFSA)2) and cyclopentyl methyl ether (CPME) and elucidated its crystal structure. We found that the obtained Mg(TFSA)2(CPME)2 exhibits solid-state ionic conductivity at room temperature and a high Mg-ion transference number of 0.74. Contrastingly, most Mg-conductive inorganic solid electrolytes require heating above 150–300°C to exhibit ionic conductivity. These results further prove the suitability of molecular crystals as candidates for Mg-ion-conducting solid electrolytes.

“…5,6 The replacement of these liquid electrolytes by a solid state ionic conductor could be a solution. Previous studies have reported Mg 2+ ion conducting materials as MgS-P 2 S 5 -MgI 2 glasses 7 and Mg-containing NASICON materials such as MgZrPO 4 , MgZr 4 (P 6 O 4 ) 6 and other Mg x Zr y (PO 4 ) z compositions. [8][9][10] Even so, these materials reach a significant ionic conductivity only at high temperatures: 10 -7 S.cm -1 at 200°C and 10 -6 S.cm -1 at 500°C for the sulfide-based glasses and for the NASICON phases, respectively.…”

Investigation of Mg(BH₄)(NH₂)-Based Composite Materials with Enhanced Mg²⁺ Ionic Conductivity

Nowadays, the development of rechargeable Mg batteries remains a challenge, especially due to the difficulty to find a non-corrosive liquid electrolyte with suitable ionic transport properties. A possible improvement could come from a solid electrolyte, such as Mg(BH 4)(NH 2), which has been recently reported as a solid-state Mg-ion conductor. In this study, its synthesis parameters are carefully investigated. The formation of an additional phase is reported, whose amount is decreased by optimizing the synthesis parameters and especially by increasing the ball-milling speed. For the first time, 11 B MAS-NMR spectroscopy is applied to this Mg-B-N-H system: it reveals that an additional phase is always present even in an amorphous state. Interestingly, it strongly influences the ionic conduction properties. Indeed, the as-obtained borohydride-amide composite exhibits a high conductivity of 3.10-6 S.cm-1 at 100°C, one of the highest ever-reported ionic conductivity for a Mg 2+ solid conductor at such low temperature.
