Bismuth chalcogenides Bi 2 X 3 (X = O, S, Se) represent a unique type of materials in diverse polymorphs and configurations. Multiple intrinsic features of Bi 2 X 3 such as narrow bandgap, ion conductivity, and environmental friendliness, have render them attractive materials for a wide array of energy applications. In particular, their rich structural voids and the alloying capability of Bi enable the chalcogenides to be alternative electrodes for energy storage such as hydrogen (H), lithium (Li), sodium (Na) storage and supercapacitors. However, the low conductivity and poor electrochemical cycling are two key challenges for the practical utilization of Bi 2 X 3 electrodes. Great efforts have been devoted to mitigate these challenges and remarkable progresses have been achieved, mainly taking profit of nanotechnology and material compositing engineering. In this short review, we summarize state-of-the-art research advances in the rational design of diverse Bi 2 X 3 electrodes and their electrochemical energy storage performance for H, Li, and Na and supercapacitors. We also highlight the key technical issues at present and provide insights for the future development of bismuth based materials in electrochemical energy storage devices.

Bismuth oxide may be a promising battery material due to the high gravimetric (690 mAh g−1) and volumetric capacities (6280 mAh cm−3). However, this intrinsic merit has been compromised by insufficient Li-storage performance due to poor conductivity and structural integrity. Herein, we engineer a heterostructure composed of bismuth oxide (Bi2O3) and bismuth sulphide (Bi2S3) through sulfurization of Bi2O3 nanosheets. Such a hierarchical Bi2O3-Bi2S3 nanostructure can be employed as efficient electrode material for Li storage, due to the high surface areas, rich porosity, and unique heterogeneous phase. The electrochemical results show that the heterostructure exhibits a high Coulombic efficiency (83.7%), stable capacity delivery (433 mAh g−1 after 100 cycles at 600 mA g−1) and remarkable rate capability (295 mAh g−1 at 6 A g−1), notably outperforming reported bismuth based materials. Such superb performance indicates that constructing heterostructure could be a promising strategy towards high-performance electrodes for rechargeable batteries.

“…We have fabricated CNT-wired LiCo 0.5 Mn 0.5 PO 4 nanocomposites by a one-pot hydrothermal route. [62] The LiCo 0.5 Mn 0.5 PO 4 -CNT discharged a high capacity of 151 mAh g −1 with an energy density of 620 mWh g -1 , which is 17% greater than that of the pristine LiCo 0.5 Mn 0.5 PO 4 . This nanocomposite retained 92% of the reversible capacity retention over 30 cycles and delivered 116 mAh g −1 at a rate of 1 C (170 mAh g −1 ), which was superior to most reports for LiCoPO 4 related materials.…”

In spite of an ongoing advancement, current popular EES systems including Li-ion batteries (LIBs), supercapacitors (SCs), and redox flow cells (RFCs) are limited by severe performance challenges of electrode materials in terms of low energy and power density as well as short durability. To mitigate the issues, carbon nanomaterials could be introduced to these EES systems, taking advantage of their unique geometry, excellent conductivity, large surface area, and intrinsic flexibility. Numerous carbon nanomaterial based EES systems, where carbon nanomaterials are adopted as either conducting additive or active electrode, have been developed and demonstrated appealing energy and power features. With the capability to enhance the structural and electrochemical properties of electrodes, carbon nanomaterials and their derivatives offer a wide range of possibilities to design advanced EES devices that can meet our growing energy and power demands in the future.A number of reviews have been published in the past few years on the application of carbon nanomaterials in EES. [5][6][7][8] However, this area is so active and new works accumulate very quickly. Therefore, it is helpful to update the new designs and outcomes. This progress report will summarize the most exciting recent (from the year 2010 onwards) advances in the application of carbon nanomaterials with different dimensions, i.e., 0D fullerene, 1D CNT, 2D graphene, and 3D assemblies of CNT and graphene, in EES systems, and highlight the new trends in the field. Besides the repetitively reviewed LIBs and SCs, this work will also deal with another important system, the RFC, which has been rejuvenated recently and is becoming increasingly vital for large scale energy storage. The recent EES applications of carbon nanomaterials will be discussed based on their dimensions. Structure and Properties of Various Nanostructured CarbonFullerenes, CNTs, and graphene all present conjugated π electron systems. The unique electronic configuration combined with geometric structure endows them with extraordinary properties, which make them superior to their competitors for specific applications such as EES. 0D FullerenesFullerene normally has a hollow sphere or ellipsoid shape.
