Abstract

New electrolytes are necessary for the development of eco-friendly and cost-effective solid-state magnesium batteries. Methylamine borane-magnesium borohydride Mg(BH₄)₂-CH₃NH₂BH₃ combined with MgO is suggested as a novel solid state electrolyte. In fact, Mg(BH₄)₂-CH₃NH₂BH₃ 0.33–0.67 (molar fraction) is a viscous liquid at room temperature, but it can be stabilized in the solid state after the incorporation of 75 wt% of MgO. The obtained composite exhibits remarkable Mg²⁺ conductivity, achieving approximately 10^–5 S cm^-1 at 25 °C and 10^–4 S cm^–1 at 65 °C.

用于镁电池的 Mg(BH4)2-CH3NH2BH3@MgO 固态电解质

新型电解质对于开发环保且经济高效的固态镁电池十分必要。甲胺硼烷-硼氢化镁 Mg(BH4)2-CH3NH2BH3 与氧化镁的结合被认为是一种新型固态电解质。事实上，Mg(BH4)2-CH3NH2BH3 0.33-0.67（摩尔分数）在室温下是一种粘性液体，但在加入 75 wt%的氧化镁后，它可以稳定在固态。所获得的复合材料具有显著的 Mg2+ 导电性，在 25 °C 时约为 10-5 S cm-1，在 65 °C 时约为 10-4 S cm-1。

期刊介绍： Energy is the single most valuable resource for human activity and the basis for all human progress. Materials play a key role in enabling technologies that can offer promising solutions to achieve renewable and sustainable energy pathways for the future. Materials for Renewable and Sustainable Energy has been established to be the world''s foremost interdisciplinary forum for publication of research on all aspects of the study of materials for the deployment of renewable and sustainable energy technologies. The journal covers experimental and theoretical aspects of materials and prototype devices for sustainable energy conversion, storage, and saving, together with materials needed for renewable fuel production. It publishes reviews, original research articles, rapid communications, and perspectives. All manuscripts are peer-reviewed for scientific quality. Topics include: 1. MATERIALS for renewable energy storage and conversion: Batteries, Supercapacitors, Fuel cells, Hydrogen storage, and Photovoltaics and solar cells. 2. MATERIALS for renewable and sustainable fuel production: Hydrogen production and fuel generation from renewables (catalysis), Solar-driven reactions to hydrogen and fuels from renewables (photocatalysis), Biofuels, and Carbon dioxide sequestration and conversion. 3. MATERIALS for energy saving: Thermoelectrics, Novel illumination sources for efficient lighting, and Energy saving in buildings. 4. MATERIALS modeling and theoretical aspects. 5. Advanced characterization techniques of MATERIALS Materials for Renewable and Sustainable Energy is committed to upholding the integrity of the scientific record. As a member of the Committee on Publication Ethics (COPE) the journal will follow the COPE guidelines on how to deal with potential acts of misconduct. Authors should refrain from misrepresenting research results which could damage the trust in the journal and ultimately the entire scientific endeavor. Maintaining integrity of the research and its presentation can be achieved by following the rules of good scientific practice as detailed here: https://www.springer.com/us/editorial-policies
