					</table><p>Researchers from Japan have developed a novel Mg2+ (magnesium ions) conductor with practically applicable superconductivity, which overcomes their poor conductivity in solids at room temperature.</p>
<p>Solid-state rechargeable lithium-ion (Li+) batteries dominate the energy storage applications in the industry. But lithium is a rare earth metal, and dependence on the element will likely lead to a rapid decline in resources and subsequent price hikes.</p>
<p>According to Wood Mackenzie, a global research and consultancy firm, the cumulative lithium-ion battery capacity will likely <a href="https://mercomindia.com/global-lithium-ion-battery-capacity-to-increase-five-fold/" target="_blank" rel="noopener">rise</a> over five-fold to 5,500 GWh between 2021 and 2030.</p>
<p>Recent Japanese research has shown that Mg2+-based batteries can be an alternative to Li+.</p>
<p>The earth&#8217;s crust holds ample magnesium, and Mg2+-based energy devices are said to have high energy densities, high safety, and low cost. But the broad application of Mg2+ is limited by its poor conductivity in solids at room temperature.</p>
<p>In a new study, a research team from the Tokyo University of Science (TUS) reported a solid-state Mg2+ conductor with the highest superionic conductivity for the first time. This discovery was made after the team researched a class of materials called metal-organic frameworks (MOFs). An additional &#8220;guest molecule,&#8221; acetonitrile, was introduced into the pores of the MOF, which succeeded in strongly accelerating the conductivity of Mg2+.</p>
<p>In a final impedance test to measure ionic conductivity, the team found that the Mg2+ electrolyte exhibited a superionic conductivity &#8212; the highest ever reported conductivity for a crystalline solid containing Mg2+.</p>
<p>These findings of this study not only reveal the novel MOF-based Mg2+ conductor as a suitable material for battery applications and provide critical insights into the development of future solid-state batteries.</p>
<p>&#8220;In this study, we have demonstrated that if the crystal structure and surrounding environment are well-designed, then a solid-state high-conductivity conductor is well within research,&#8221; explains Junior Associate Professor Masaaki Sadakiyo of TUS who led the study.</p>
