Constructing layered double hydroxide derived heterogeneous Ti₃C₂T_x@S–MCoP (M = Ni, Mn, Zn) with S-vacancies to boost sodium storage performance

Abstract

Poor conductivity and huge volume changes severely limit the application of layered double hydroxides (LDHs) derived transition metal phosphides (TMPs) as anode materials in sodium ion batteries (SIBs). To solve...

“…Li et al prepared Ti 3 C 2 T x hollow microspheres using PMMA microspheres as sacrificial templates and grew S-doped NiCoP nanosheets with abundant S vacancy on Ti 3 C 2 T x surface by a stepwise strategy to obtain the hollow Ti 3 C 2 T x @S-NiCoP. [143] When used as SIBs anode, Ti 3 C 2 T x @S-NiCoP has a reversible capacity of 563 mAh g −1 at 0.2 A g −1 . It also provides excellent cycle stability for more than 3000 cycles with a capacity decay of 0.005% per cycle.…”

A strongly coupled 3D SnS2@Ti3C2Tx heterojunction with vacancies for high-efficiency sodium storage

“…24 In a separate study, heterogeneous Ti 3 C 2 T x @S-MCoP (M = Ni, Mn, Zn) composites were designed, which significantly improved sodium storage performance. 25 In both investigations, the Ti 3 C 2 T x nanosheets played a pivotal role by facilitating charge transfer and redox kinetics, while effectively mitigating volume changes during the storage process.…”
