Bismuth Sulfide–Integrated Carbon Derived from Organic Ligands as a Superior Anode for Sodium Storage

et al. 2019

Bismuth sulfide (Bi2S3) as a potential Na‐storage material relies upon its special layered structure and high volumetric capacity. However, the electrochemical activity of pure Bi2S3 is greatly limited during the sodiation/desodiation process. The integration of Bi2S3 with reduced graphene and a particular carbon is explored to acquire active composite anodes for sodium ion batteries (SIBs). This special carbon is based on trimesic acid (H3BTC) as a carbon source, which effectively prevents the aggregation of Bi2S3 particles in the synthesis process. Compared with other carbon sources, this type of carbon source is more likely to diffuse into the interior of the precursor hole. Hence, the Bi2S3/C indicates higher reversible capacities (368 and 314 mAh g−1 after 100 cycles and 200 cycles at 100 mA g−1) than bare Bi2S3 or Bi2S3@RGO. Thus, Bi2S3/C is considered as a prospective electrode material for rechargeable batteries.

“…During the discharge and charge processes in Figure e, reversible products NaBiS 2 , Bi metal, and Na‐Bi alloy were identified. According to these reaction products and other related references, it could be inferred that some part of the reactions is irreversible, and the mechanism in this system is a combination of conversion reaction and alloying reaction. The alloying reactions started from 0.67 V. Thus, four main redox reactions were part of the whole sodiation and desodiation process.…”

Exploring novel electrode materials with high rate capability and outstanding cycling stability is an urgent issue for sodium‐ion batteries (SIBs). Herein, Bi2S3 nanorods anchoring on reduced graphene oxide (Bi2S3@rGO composite) are designed and synthesized for sodium storage applications. With the contributions from the unique structure, the surface C—S bonds on rGO, and the synergetic effects from the components, the composite delivers remarkable electrochemical performances. The results indicate that the strategy of chemically constructing a composite structure can be very promising for advanced electrodes of SIBs.

“…For the high‐resolution spectra of Bi 4f, two peaks at 159.0 and 164.1 eV can be observed in Figure f, but the S peak recorded in the XPS pattern of Bi 2 S 3 (at 162 eV, as shown in Figure S2b, Supporting Information) was not observed. This result suggested that there was no Bi 2 S 3 phase in the final product of Bi@C . Furthermore, as seen in the C 1s XPS spectrum shown in Figure S3a, Supporting Information, some trace of oxygen functional groups was detected in the carbon shell.…”

A new type of a mesoporous carbon‐coated bismuth (Bi@C) composite in the form of nanorods is fabricated and used as anode material in a potassium‐ion battery (KIB). The rod‐like Bi core is composed of nanoparticles and confined by a shell of amorphous carbon. The KIB with such Bi@C anode exhibits a high storage capacity of 425 mAh g−1 at 0.2 A g−1. The mesoporous Bi@C, with a large surface area and an appropriate pore size is in close contact with the electrolyte and facilitates the diffusion of K+ ions. The carbon shell soothes the mechanical stresses owing to the volumetric changes of the anode during charging and discharging of the battery, preventing the degradation of active material and delivering a cyclic stability of over 500 cycles. This superior performance demonstrates the importance of a structural design that can offer a new pathway to anode development in KIB as well as in other energy storage devices.
