“…However, the large c ‐direction atomic spacing weakens the interlayer van der Waals interaction, which results in poor electron transportation from sheet to sheet and finally causes remarkable capacity loss and inferior rate capability . Recently, a number of works have focused on improving the electrical conductivity of SnS 2 by combining it with conductive carbonaceous materials such as reduced graphene oxide (rGO) and carbon nanotubes (CNTs) .

Tin disulfide, as a promising high-capacity anode material for sodium-ion batteries, exhibits high theoretical capacity but poor practical electrochemical properties due to its low electrical conductivity. Constructing heterostructures has been considered to be an effective approach to enhance charge transfer and ion-diffusion kinetics. In this work, composites of SnS /Sb S heterostructures with reduced graphene oxide nanosheets were synthesized by a facile one-pot hydrothermal method. When applied as anode material in sodium-ion batteries, the composite showed a high reversible capacity of 642 mA h g at a current density of 0.2 A g and good cyclic stability without capacity loss in 100 cycles. In particular, SnS /Sb S heterostructures exhibited outstanding rate performance with capacities of 593 and 567 mA h g at high current densities of 2 and 4 A g , respectively, which could be ascribed to the dramatically improved Na diffusion kinetics and electrical conductivity.

Summary In the context of large scale and low‐cost energy storage, the emerging potassium‐ion batteries (PIBs) are one potential energy storage system. Graphite, a commercial anode material widely used in lithium‐ion batteries (LIBs), can be directly applied to PIBs through forming the stage I graphite intercalation compound (KC8). However, the dramatic volume expansion during the formation of KC8 can result in poor cycling performance. In this work, one Al2O3 atomic layer coated on the surface of graphite via atomic layer deposition (ALD) process, aiming to construct a stable solid electrode interface and enhance the performance of graphite anode in PIBs. The electrochemical performance analysis shows that the 20 cycles Al2O3 deposited graphite have improved cycle stability of 223 mAh g−1 at 50 mA g−1 after 50 cycles compared with the raw graphite anode of 92 mAh g−1.

Flexible energy storage devices have gained significant attention because of the increasing needs of bendable displays, wearable electronics, and flexible displays. Flexible Na‐based rechargeable batteries are the promising power sources in such products due to their low cost and wide availability. In this review, we firstly introduce the structural superiority of flexible Na‐based batteries and summarize their main components including cathodes, electrolytes, and anodes. Moreover, fabrication of their flexible components is discussed in detail, with specific emphasis on material selection, particularly for solid‐state electrolytes. This is followed by an overview highlighting recent progress in the development of prototypes of flexible Na‐ion batteries and beyond. Finally, perspectives on future challenges for the development of flexible Na batteries are proposed.
