Two-Dimensional\nTiO₂/TiS₂ Hybrid\nNanosheet Anodes for High-Rate Sodium-Ion Batteries

Abstract

The\nsodium-ion battery (NIB) is promising for next-generation energy\nstorage systems. One promising anode material is titanium dioxide\n(TiO₂). However, the sluggish sodiation/desodiation kinetics\nof TiO₂ hinders its application in NIBs. Herein, we converted\nTiO₂ into a two-dimensional (2D) TiO₂/TiS₂ hybrid to improve its sodium storage capability. The 2D TiO₂/TiS₂ hybrid nanosheet electrode provides high\nkinetics and excellent cycling performance for sodium-ion storage.\nThis work provides a promising strategy to develop 2D hybrid nanomaterials\nfor high-performance sodium storage devices.
