One of the greatest challenges for our society is providing powerful electrochemical energy conversion and storage devices. Rechargeable supercapacitors, lithium-ion batteries and fuel cells are three promising candidates in terms of energy densities and power densities. Transition metal-based nanomaterials (TMNs) including metal oxides, metal nitride, metal carbide and metal sulfide are currently of interest for such devices because of their eco-friendliness, novel size effects, significantly enhanced kinetics, and so on. Different types of transition metal-based materials usually have different properties around conductivity, activity and stability. Therefore, different materials could be designed or modified for certain application with high performance or high conversion efficiency.
Rational design of earth-abundant transition metal-based nanomaterials is of great importance for developing next-generation electrocatalysts or electrode materials for electrochemical energy devices. The development of inexpensive catalysts or electrode materials would meet the demand in electrochemical energy storage and conversion systems. Due to advantages of transition metals (unique d electron configurations, low cost nature, synergistic effect of multi-metal atoms, excellent stability), there are significant advances for the energy systems of electrochemical supercapacitors (ECs), batteries, water splitting and fuel cells (FCs). Understanding the novel design, fabrication, applications performance of these nanomaterials, and its catalytic mechanism is critical for the current challenges and future prospects of TMNs in energy conversion and storage applications.
This Research Topic aims to highlight high-quality original research and review articles covering TMNs for energy conversion and storage. In particular, we will feature new developments in the synthesis of transition metal-based nanomaterials and their applications on energy conversion and storage. Subjects covered may include, but are not limited to:

- metal–air (oxygen) batteries
- supercapacitor
- fuel cells
- Lithium ion batteries
Article types welcomed:
