Abstract Low-cost sodium ion batteries (SIBs) have shown hopeful perspective for large-scale energy storage systems. However, the development of carbon anode materials with high gravimetric and volumetric capacity is still a challenge. Herein, we propose a novel dense and N, P co-doped carbon derived from high density crosslinked bacterial cellulose (BC) with hexachlorocyclotriphosphazene (HCCP), which simultaneously combines high gravimetric and volumetric capacity. The as-prepared electrode de...

Carbon-based materials have been considered as the most promising anode materials for both sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs), owing to their good chemical stability, high electrical conductivity, and environmental benignity. However, due to the large sizes of sodium and potassium ions, it is a great challenge to realize a carbon anode with high reversible capacity, long cycle life, and high rate capability. Herein, by rational design, N-doped 3D mesoporous carbon nan...

Abstract Based on the conversion and alloying reactions, antimony sulfide (Sb 2 S 3 ) with a theoretical discharge specific capacity of 946 mAh g −1 is a hopeful anode material for lithium/sodium ion batteries. Nevertheless, the poor electronic conductivity of Sb 2 S 3 and the serious volume expansion during alloying reaction bring about the rapid capacity fading, which severely hinder its practical application. The design of morphology/structure and/or combining with carbon materials is the com...

Abstract Few-layer 2D Sb 2 S 3 (2D-SS) nanosheets are synthesized using a simple and scalable exfoliation method assisted by Li intercalation, which are employed as bifunctional anodes for both lithium ion batteries (LIBs) and sodium ion batteries (SIBs) for the first time. The 2D-SS nanosheets present a well-defined layered structure with an ultrathin thickness of 3.8 nm and a lateral size as large as several tens of micrometers, giving rise to an extremely large aspect ratio and surface area, ...

Abstract Low energy density is the key issue that needs to be addressed for sodium ion batteries. Antimony sulfide (Sb2S3) with high theoretical capacity is considered as an ideal anode, but it suffers from poor electrochemical activity and consequently, low energy density. Simple hollow Sb2S3 structures with high electrochemical activity offer high gravimetric energy density, while large internal voids significantly decrease the volumetric energy density. Here, multi-shell Sb2S3 was synthesized...

In response to the increasing concern for energy management, molybdenum disulfide (MoS2) has been extensively researched as an attractive anode material for sodium-ion batteries (SIBs). The proficient cycling durability and good rate performance of SIBs are the two key parameters that determine their potential for practical use. In this study, nature-inspired three-dimensional (3D) MoS2 ultrathin marigold flower-like microstructures were prepared by a controlled hydrothermal method. These micros...

: Developing bifunctional electrocatalysts with high activities and long durability for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is crucial toward the practical implementation of rechargeable metal-air batteries. Here, a 3D nanoporous graphene (np-graphene) doped with both N and Ni single atoms/clusters is reported. The predoping of N by chemical vapor deposition (CVD) dramatically increases the Ni doping amount and stability. The resulting N and Ni codoped np-grap...

Antimony sulfide (Sb2S3) has been employed for materials of the potential anode in sodium-ion batteries (SIBs) because it possesses a high theoretical capacity. However, volume variations coupled with sluggish diffusion kinetics cause rapid capacity degradation and cyclic instability during the sodiation/desodiation process. Here, we introduce a simple strategy to develop nitrogen-doped carbon-encapsulated antimony sulfide nanowire (Sb2S3@N-C) composites for the anode in SIBs. The resulting comp...

Abstract In this work, tin disulfide (SnS2) embedded in nitrogen and sulfur dual-doped carbon (denoted as SnS2/NSDC) nanofibers are synthesized using a facile electrospinning technique for the first time. The exterior of the nanofibers is decorated through the SnS2 nanosheet, and the interior of carbon nanofibers is embedded with SnS2 nanoparticles. Benefit from the unique structure and morphology, SnS2/NSDC nanofibers show excellent electrochemical performance. In Na half-cell, SnS2/NSDC nanofi...
