Nanoconfined NaAlH₄ Conversion Electrodes for Li Batteries.

ABSTRACT: In the past, sodium alanate, NaAlH₄, 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. NaAlH₄ has recently been considered for Li-ion storage as a conversion-type anode in Li-ion batteries. Here, NaAlH₄ nanoconfined in carbon scaffolds as an anode material for Li-ion batteries is reported for the first time. Nanoconfined NaAlH₄ was prepared by melt infiltration into mesoporous carbon scaffolds. In the first cycle, the electrochemical reversibility of nanoconfined NaAlH₄ was improved from around 30 to 70% compared to that of nonconfined NaAlH₄. Cyclic voltammetry revealed that nanoconfi
