However, their progresses are prevented by the inferior cycling performance caused by severe volumetric change and pulverization during the (de)sodiation process. To address this issue, herein an alloying strategy was proposed and nanoporous bismuth (Bi)–antimony (Sb) alloys were fabricated by dealloying of ternary Mg-based precursors.

Antimony (Sb) is regarded as the most promising positive electrode material for LMBs owing to its low cost and high cell voltage. Its high melting temperature of 631 °C is typically reduced by alloying with lead, tin, or bismuth without a significant decrease in cell voltage [ 3, 4 ].

The larger atomic size of bismuth causes it to have poorer orbital overlap with the carbene centre than its lighter congeners. Additionally, due to its metallic nature, organo-bismuth compounds exhibit significantly different reactivity and stability. Therefore, the synthesis of carbene-stabilized bismuth species is even more challenging.
