In order to acquire reproducible electrodes relevant for Li ion batteries new MgH 2 electrodes are successfully obtained from homogenous slurries in N-Methyl-2-Pyrrolidone "NMP" solvent. The electrodes are aimed to elucidate the contribution of the cell components to the electrochemical cycling, in terms of morphology and composition. Various electrode preparations were tested and compared regarding their interaction with Li in a half-cell. The obtained electrochemical cycling curves are discussed according to the ball-milling-induced structural morphology changes and presence of carbon additives, along with the effect of the kinetic rate on the conversion reaction mechanism.

“…1,2 Indeed, MgH 2 has shown good reversibility and has been an active material of choice in several reports. [3][4][5][6][7][8] The high capacity for MgH 2 is achieved through a conversion reaction in which the magnesium hydride reacts with lithium ions to form LiH and pure magnesium (MgH 2 + 2Li + + 2e -↔ 2LiH + Mg). However, a recent study of TiH 2 as an active anode material suggests that the simple mechanism used to describe the behaviour of MgH 2 is not universal to all MH x hydrides.…”

Li-Driven Electrochemical Conversion Reaction of AlH₃, LiAlH₄, and NaAlH₄

The conversion reaction of AlH3, LiAlH4, and NaAlH4 complex hydrides with lithium has been examined electrochemically. All compounds undergo a conversion reaction in which one equivalent of LiH is formed for each equivalent of hydrogen contained in the hydride material. Decomposition of the hydrides follows different paths depending on the nature of the alkali metal but leads in all cases to pure metallic aluminum. Such very fine and reactive Al particles are able to readily form an alloy with Li at a lower potential. Alternatively, thermal decomposition of alane has been used to produce highly porous aluminum able to react with lithium to form the AlLi alloy directly. Constant current charge/discharge cycling, cyclic voltammetry, and in-operando XRD were utilized to characterize the performance of these materials and to interpret the reaction paths depending of the complex hydride compositions.

“…The capacity of MgH 2 can be improved by limiting the amount of inserted lithium [149], through careful formulation (e.g., choice of binder) and choice of electrolyte. Hereby, a capacity retention for MgH 2 of 542 mAh/g over 40 cycles has been achieved [150].…”

Hydrogen has a very diverse chemistry and reacts with most other elements to form compounds, which have fascinating structures, compositions and properties. Complex metal hydrides are a rapidly expanding class of materials, approaching multi-functionality, in particular within the energy storage field. This review illustrates that complex metal hydrides may store hydrogen in the solid state, act as novel battery materials, both as electrolytes and electrode materials, or store solar heat in a more efficient manner as compared to traditional heat storage materials. Furthermore, it is highlighted how complex metal hydrides may act in an integrated setup with a fuel cell. This review focuses on the unique properties of light element complex metal hydrides mainly based on boron, nitrogen and aluminum, e.g., metal borohydrides and metal alanates. Our hope is that this review can provide new inspiration to solve the great challenge of our time: efficient conversion and large-scale storage of renewable energy.
