Special Issue Information

Dear Colleagues,

Bismuth-based nanomaterials are eco-friendly and of high biocompatibility, and they are easy to process in terms of both composition and structural regulations, including morphology structure and crystal structure. These aspects could significantly affect the performances of bismuth-based materials, endowing them with strong potential for application in numerous fields, especially energy storage and energy conversion, e.g.,  as electrode materials, modifiers, or additives in energy storage devices. 

This Special Issue will cover promising and novel research trends in the synthesis of bismuth-based materials, characterization via advanced technologies, and the exploration of their applications in energy storage and conversion. The topics of interest include but are not limited to the following:

  • Synthesis and characterization of bismuth-based materials via novel and advanced techniques and methodologies;
  • Exploration of bismuth-based materials as electrode materials for rechargeable aqueous and non-aqueous batteries;
  • Exploration of bismuth-based materials as additives or modifiers for metal anodes (Li, Na, K and Zn metal anode);
  • Exploration of bismuth-based materials for energy conversion (electrocatalysis, photo-electrocatalysis, and CO2 reduction reactions);
  • Practical application of bismuth-based materials in energy storage and conversion devices;
  • Construction of bismuth-based composite materials.

The exploration of cost-effective and sustainable biomass-derived carbon materials as electrodes for energy conversion and storage has gained extensive attention in recent research studies. However, the selection of the biomass and the electrochemical performance regulation of the derived biochar, as well as their interrelationship still remain challenging for practical application. Herein, corn wastes with high carbon content (>40%), corn cob and corn silk, were selected as precursors for the preparation of high value-added and high yield carbon materials via a modified synthetic process. Uniquely, this work put emphasis on the theoretical and experimental investigations of how the biomass properties influence the composition and nanostructure regulation, the electrolyte ion adsorption free energy, and the electrical conductivity of the derived carbon materials as well as their electrochemical performance optimization. Owing to the favorable specific surface area, the hierarchical porous structure, and the diverse elemental distribution, corn cob and corn silk derived carbon materials (CBC and SBC) present great potential as promising electrodes for alkaline aqueous zinc batteries and supercapacitors. The assembled CBC//Zn and SBC//Zn zinc batteries deliver high energy densities of 63.0 Wh kg−1 and 39.1 Wh kg−1 at a power density of 575 W kg−1, with excellent cycling performance of 91.1% and 84.3% capacitance retention after 10,000 cycles. As for the assembled symmetric supercapacitors, high energy densities of 14.9 Wh kg−1 and 13.6 Wh kg−1, and superior long-term cycling stability of 99.3% and 96.6% capacitance retention after 20,000 cycles could be achieved. This study highlights the advantages of utilizing corn cob and corn silk as carbon sources on the designed synthesis of carbon electrodes, and presents a meaningful perspective in the investigation of biomass-derived carbon materials and their potential applications in rechargeable devices.
