“…Moreover, the built-in electric field with an n → p direction could facilitate sodium ions in the heterostructure leading to a fast ion transport kinetics. The built-in electric field and matched energy band of the heterostructures provide the multi-component metal sulfides with better electronic conductivity and faster ion diffusion [59][60][61]. Constructing heterostructures with various transition metal sulfides can enhance the electrochemical activity and sodium storage performance [33].…”

Sodium-ion battery (SIB), one of most promising battery technologies, offers an alternative low-cost solution for scalable energy storage. Developing advanced electrode materials with superior electrochemical performance is of great significance for SIBs. Transition metal sulfides that emerge as promising anode materials have advantageous features particularly for electrochemical redox reaction, including high theoretical capacity, good cycling stability, easily-controlled structure and modifiable chemical composition. In this review, recent progress of transition metal sulfides based materials for SIBs is summarized by discussing the materials properties, advanced design strategies, electrochemical reaction mechanism and their applications in sodium-ion full batteries. Moreover, we propose several promising strategies to overcome the challenges of transition metal sulfides for SIBs, paving the way to explore and construct advanced electrode materials for SIBs and other energy storage devices.

Sodium-ion batteries (SIBs) based on flexible electrode materials are being investigated recently for improving sluggish kinetics and developing energy density. Transition metal selenides present excellent conductivity and high capacity; nevertheless, their low conductivity and serious volume expansion raise challenging issues of inferior lifespan and capacity fading. Herein, an in-situ construction method through carbonization and selenide synergistic effect is skillfully designed to synthesize a flexible electrode of bone-like CoSe 2 nano-thorn coated on porous carbon cloth. The designed flexible CoSe 2 electrode with stable structural feature displays enhanced Na-ion storage capabilities with good rate performance and outstanding cycling stability. As expected, the designed SIBs with flexible BLÀ CoSe 2 /PCC electrode display excellent reversible capacity with 360.7 mAh g À 1 after 180 cycles at a current density of 0.1 A g À 1 .[a] Dr.
