Abstract

In this work, we evaluate the electrochemical properties of MBH₄-C₆₀ (M = Li⁺, Na⁺) nanocomposites for potential use as a solid-state electrolyte in alkali-ion batteries. The enhancement of ionic conductivity for MBH₄ was achieved through the addition of C₆₀ and partial dehydrogenation, resulting in an electrolyte with significantly higher ionic conductivity when compared to the pure MBH₄. This improvement is attributed to the nanoionic destabilization of the MBH₄ salt due to the affinity of the BH₄− anion for C₆₀ and partial dehydrogenation of the MBH₄ through heating. The LiBH₄-C₆₀ nanocomposite was successfully paired with two anodes (graphite and lithium titanate) and two cathodes (LiFePO₄ and TiS₂) and galvanostatically cycled. The NaBH₄-C₆₀ nanocomposite showed nearly a 4-order-of-magnitude increase in ionic conductivity versus pure NaBH₄ and demonstrated reversible sodium stripping and plating in a symmetric cell.
