AI Overview

Bismuth powder can be used in energy storage as an electrode material, particularly for

alkali-ion batteries, due to its high theoretical capacity. However, a major challenge is its significant volume expansion during cycling, which can degrade performance. To overcome this, bismuth powder is often processed into nanoparticles and combined with conductive carbon materials like graphene or mesoporous carbon to form composites, improving both stability and conductivity. Bismuth is also explored for use in other applications like supercapacitors and redox flow batteries, notes ScienceDirect, ScienceDirect.com, The Royal Society of Chemistry, Wiley Online Library, and IOPscience.

Anode material: Bismuth's high theoretical volumetric specific capacity makes it promising as an anode for sodium-ion (SIB), potassium-ion (PIB), and lithium-ion (LIB) batteries.
Handling volume expansion: The significant volume change that occurs during battery cycling is a major drawback. To mitigate this, bismuth is often synthesized into nanoparticles and embedded within a carbon-based structure like graphene, carbon fibers, or mesoporous carbon to buffer the expansion.
Improved performance: These composites have demonstrated high reversible capacities, excellent rate performance, and improved cycle stability compared to pure bismuth. For example, a Bi/CMK-3 anode showed stable performance over 2,500 cycles for SIBs.
Other applications: Bismuth-based compounds are also being explored as cathode materials, for example, bismuth vanadate (BVO) for various battery types and supercapacitors, according to Wiley Online Library.
Redox flow batteries: Bismuth metal can be used as an electrocatalyst on carbon paper anodes to improve the reversibility of redox couples in aqueous redox flow batteries, notes IOPscience.
Zinc-air batteries: Bismuth oxide can be used as an additive in zinc-air battery anodes to inhibit dendrite formation, as shown in this study on ScienceDirect.com.

Electrode material: Bismuth (II) oxide is used in supercapacitor electrodes due to its high surface area, electrical conductivity, and stability.
Hybrid devices: Bismuth-based perovskites are also being researched for use in hybrid energy harvesting and storage devices like photo-supercapacitors, which can combine light and electrochemical energy storage, according to ScienceDirect.com www.sciencedirect.com
