Bismuth chalcogenide compounds Bi2×3 (X=O, S, Se): Applications in electrochemical energy storage

Abstract

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.

“…Transition metal chalcogenides have raised considerable interest due to their several advantages such as high theoretical capacity and high energy density . However, the large volume swelling that leads to the poor capacity retention and the dissolution of sulfide/selenides species in organic electrolyte still inhibit their practical applications . Constructing nanostructures is an effective process to improve the cycle stability.…”

“…Nevertheless, the pursuit towards high energy density batteries for EVs is significantly hampered by the low specific capacity of the commercialized graphite anodes . Various anode materials with higher capacity have been extensively explored in recent years, among which alloy‐type anode materials are the most promising alternatives to graphite owing to their well‐defined and low potential plateaus during the alloying reaction with lithium, which is essential for a battery of steady working voltage In the alloy‐type family, bismuth‐based materials also attracted considerable attentions .…”
