An Sn doped 1T–2H MoS₂ few-layer structure embedded in N/P co-doped bio-carbon for high performance sodium-ion batteries

Abstract

A facile method for fabricating Sn doped 1T-2H MoS₂ embedded in N/P co-doped bio-carbon is developed using natural chlorella as an adsorbent and a nanoreactor. When used as an anode for sodium-ion batteries, it delivers an excellent rate performance (167 mA h g^-1 at 15 A g^-1), high capacity (533 mA h g^-1 after 50 cycles at 0.1 A g^-1), and superior long-term cycling stability (320 mA h g^-1 after 500 cycles at 1 A g^-1) which are attributed to the synergistic effects of few-layer 1T-2H MoS₂ moderate Sn doping and the N/P co-doped bio-carbon.
