Nanoconfined NaAlH4 Conversion Electrodes for Li Batteries
Abstract
<p>In the past, sodium alanate, NaAlH<sub>4</sub>, has been widely investigated for its capability to store hydrogen, and its potential for improving storage properties through nanoconfinement in carbon scaffolds has been extensively studied. NaAlH<sub>4</sub> has recently been considered for Li-ion storage as a conversion-Type anode in Li-ion batteries. Here, NaAlH<sub>4</sub> nanoconfined in carbon scaffolds as an anode material for Li-ion batteries is reported for the first time. Nanoconfined NaAlH<sub>4</sub> was prepared by melt infiltration into mesoporous carbon scaffolds. In the first cycle, the electrochemical reversibility of nanoconfined NaAlH<sub>4</sub> was improved from around 30 to 70% compared to that of nonconfined NaAlH<sub>4</sub>. Cyclic voltammetry revealed that nanoconfinement alters the conversion pathway, and operando powder X-ray diffraction showed that the conversion from NaAlH<sub>4</sub> into Na<sub>3</sub>AlH<sub>6</sub> is favored over the formation of LiNa<sub>2</sub>AlH<sub>6</sub>. The electrochemical reactivity of the carbon scaffolds has also been investigated to study their contribution to the overall capacity of the electrodes.</p>
