Stable three-dimensional metal hydride anodes for solid-state lithium storage

Formation of Lightweight Ternary Polyhydrides and Their Hydrogen Storage Mechanism

“…In addition to understanding the internal mechanism of the novel hydrogen storage material, the super cell was generated as a bulk material with vacancy defects. In hydrogen storage technology with a metal hydride in the chamber, the solid-state hydride can exchange with the hydrogen gas in the chamber. − Therefore, the number of hydrogen atoms in the bulk material can be changed during the hydrogen release in the chamber. In our calculation, we considerate the super cell with hydrogen vacancies.…”

“…The metal hydride group is one of the promising materials for use in the hydrogen storage process. − The higher efficiency of hydrogen storage process, compared to the directly containing gas in a tank, is the storage process mainly using the exchanged hydrogen gas from metal hydrides. − The solid compounds in hydride forms have released and exchanged hydrogen gas in the chambers through chemical methods. The hydrogen adsorption–desorption process requires the hydrides to have high H-capability, fast storage/release reactions of hydrogen, and low operating-temperature. − Alkali hydride is a potential candidate for hydrogen storage applications because of its high H-capacity.…”

A Review of the MSCA ITN ECOSTORE—Novel Complex Metal Hydrides for Efficient and Compact Storage of Renewable Energy as Hydrogen and Electricity

“…Recently, metal hydride electrodes have been investigated in batteries using solid electrolytes such as LiBH 4 and Li 2 S-P 2 S 5 [104][105][106][107][108][109][110][111]. Solid electrolytes allow the operation of batteries at elevated temperatures at which the reaction kinetics of the hydride conversion can be greatly improved.…”

High capacity all-solid-state lithium battery enabled by in situ formation of an ionic conduction path by lithiation of MgH2

“…The reversible capacity of the Mg(BH 4 ) 2 electrode was found to be 563 mA h g À1 in a previous study. 9 However, the literature contains numerous reports on the electrochemical properties of Li batteries with hydride-based electrolytes and electrodes, [12][13][14][15][16][17][18][19][20][21][22][23][24][25] including MgH 2 electrodes, in particular. [12][13][14][15][16][17][18][19][20][21][22] The following electrochemical reaction occurs upon the insertion of Li + into MgH 2 :…”
