About this Research Topic
The shortening period of product updates for consumer electronics and the fast-expanding market for electric vehicles have placed higher demand on the performance of electrochemical energy storage technologies, e.g., lithium-ion batteries. However, traditional electrode materials have become a bottleneck restricting the continuous enhancement of their performance. Many metal oxides exhibit two or more reversible redox couples through the electrochemical process for energy storage, resulting in much higher capacity and energy density. Before their practical application in energy storage devices, some essential issues should be addressed, including the large volume variations caused by the conversion reaction during the electrochemical reactions as well as their poor electrical conductivity.
Recently, various metal oxides have been explored for use in high-performance electrochemical energy storage, including but not limited to lithium-ion batteries, sodium-ion batteries, potassium-ion batteries, and supercapacitors. It has been demonstrated that the microstructure design, as well as the modifications in crystallographic structure and surface chemistry, play important roles in the performance boost for metal oxides.
This Research Topic collection solicits the latest advances in metal oxides for potential applications in electrochemical energy storage systems. The submission of research articles, reviews, and perspectives relevant to the following topics are welcomed.
• Microstructure design and controllable synthesis of metal oxides for energy storage
• Synthesis of novel metal oxides along with the evaluation of their potential application in electrochemical energy storage
• Modifications (especially for the crystallographic and surface chemistry) on metal oxides and their effects on electrochemical performance
