Abstract:
An inorganic structure body has a free-standing structure including a fibrous member and/or a shell. The fibrous member and/or the shell include a metal and/or an inorganic material and have a three-dimensionally continuous configuration. The free-standing structure may have a structure that is based on a nonwoven fabric or a porous membrane used as a substrate.
Abstract:
A magnesium battery 10 according to the present invention includes a positive electrode 12, a negative electrode 14 having a magnesium-containing negative electrode active material, and an inorganic magnesium solid electrolyte 16 that is interposed between the positive electrode 12 and the negative electrode 14, has a complex ion structure that contains magnesium and hydrogen, and conducts magnesium ions. The inorganic magnesium solid electrolyte 16 may contain a compound having at least one selected from boron and nitrogen. The inorganic magnesium solid electrolyte may be produced by a production method that includes a heat-treatment step of mixing and heating Mg(BH4)2 and Mg(NH2)2 to form a compound having a complex ion structure that contains magnesium and hydrogen.
