Two-dimensional AlB₄/Al₂B₂: high-performance Dirac anode materials for sodium-ion batteries

Abstract

Sodium-ion batteries (SIBs) have attracted much attention due to their abundant earth-reserves and low cost. Two-dimensional (2D) Dirac materials show great application prospects as anodes for SIBs because of their...

Two-dimensional monolayer C5-10-16: a metallic carbon allotrope as an anode material for high-performance sodium/potassium-ion batteries

“…As promising alternatives to lithium-ion batteries (LIBs), sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs) have garnered significant attention owing to the abundant resources, low cost, and similar storage mechanism with LIBs. 1–4 However, many anode materials developed for LIBs are not suitable for SIBs or PIBs. 5,6 The larger ionic radii of Na + (1.02 Å) and K + (1.37 Å) than that of Li + (0.76 Å) limit the ion diffusion and cause excessive volume variations of electrode materials.…”
