One‐pot synthesis of SnS ₂ Nanosheets supported on g‐C ₃ N ₄ as high capacity and stable cycling anode for sodium‐ion batteries

Abstract

Despite being established as the most popular commercial energy storage system (ESS), lithium-ion batteries (LIBs) are still facing practical issues due to their high cost and limited availability of the lithium source. Sodium-ion batteries (SIBs), which have economic and environmental costs, but on-par performance compared to LIBs, are now being considered as the next-generation ESS. Herein, we report a facile and mass-scalable synthesis of SnS 2 nanosheets grafting on porous g-C 3 N 4 via direct solid-state reaction from tin (IV) acetate

Insights on advanced g‐C3N4 in energy storage: Applications, challenges, and future

“…The well-distributed SnS 2 nanosheets on g-C 3 N 4 , which was synthetized from tin(IV) acetate and thiourea, was prepared via a mass-scalable and facile one-pot method by Im and colleagues. 244 The synthesized SnS 2 @g-C 3 N 4 composite served as an anode-active material for SIBs with outstanding performance in terms of high capacity and ultralong cycling stability (919.6 mAh g −1 after 400 cycles at current density of 500 mA g −1 ; 602.7 mAh g −1 after 3000 cycles at current density of 2000 mA g −1 ). The excellent electrochemical properties of the obtained composites were mainly attributed to the following advantages: g-C 3 N 4 was used as the support material to effectively mitigate the volume changes of SnS 2 during charging and discharging.…”

“…ZnS was loaded on g‐C 3 N 4 (with a large amount of pyridinic nitrogen), which was conducive to enhancing Na + storage. The well‐distributed SnS 2 nanosheets on g‐C 3 N 4 , which was synthetized from tin(IV) acetate and thiourea, was prepared via a mass‐scalable and facile one‐pot method by Im and colleagues 244 . The synthesized SnS 2 @g‐C 3 N 4 composite served as an anode‐active material for SIBs with outstanding performance in terms of high capacity and ultralong cycling stability (919.6 mAh g −1 after 400 cycles at current density of 500 mA g −1 ; 602.7 mAh g −1 after 3000 cycles at current density of 2000 mA g −1 ).…”

“…Huu et al prepared a g-C 3 N 4 matrix using thiourea as the precursor and grew SnS 2 nanosheets on it via a solid-state reaction to construct a SS-CN heterostructure. 106 The morphology of the as-fabricated sample is shown in Fig. 14i, where the SnS 2 nanosheets with a thickness of around 11 nm were embedded on porous g-C 3 N 4 without restacking.…”
