Summary: Sodium-ion batteries with copper(I) sulfide anodes have gained attention for their high capacity and safety. In this study, Cu2S/CNT anodes were prepared, and the highly conductive CNTs acted as catalysts to promote the reversible reaction kinetics of Cu2S. The Cu2S/CNT anodes exhibited efficient and reversible conversion compared to pure Cu2S anodes, due to the superior electron conductivity and high surface area of CNTs, as well as their inhibition of sodium polysulfide dissolution. This research contributes to the design of conversion-type materials with reversible mechanisms.

Summary: A simple and effective sulfonation route is proposed to transform disposable polypropylene (PP)-based waste masks into value-added hard carbon (CM) anode materials for sodium-ion batteries. The sulfonation treatment improves the thermal stability of the PP molecule and introduces oxygen functional groups, resulting in a high disorder degree and minimal surface defects in the prepared CM-180 anode. The sodium-ion full cell fabricated with CM-180 as the anode and O3-NaNi1/3Fe1/3Mn1/3O2 as the cathode exhibits high energy density and outstanding rate capability.
