Supercapacitors for Next-Generation Energy Storage: Material Design and System Integration

Dear Colleagues,

A supercapacitor is an advanced energy storage device that bridges the gap between traditional capacitors and batteries. The performance of supercapacitors depends on several key components, such as active electrode materials, current collectors, electrolytes, separator, etc. Among these components, electrodes play a crucial role in supercapacitor performance by ensuring long-term durability, high-rate capability, and reliable energy delivery during repeated charge–discharge cycles. It is believed that the redox-active and electrochemically stable materials can effectively withstand volumetric changes and resist material degradation, thereby extending the device lifespan. Moreover, optimizing electrode–electrolyte interactions and designing nanostructured materials further improve ion transport, active site accessibility, and cycling durability, making them highly promising for next-generation supercapacitor applications. Therefore, this Special Issue aims to showcase manuscripts that evaluate efficient routes of stabilizing electrode materials and electrode–electrolyte interfaces for highly stable and practically viable supercapacitors.

Topics of interest include, but are not limited to, the following:

• Design and development of stable electrode materials for supercapacitors.
• Strategies to enhance long-term stability, energy and power densities.
• Electrode-electrolyte interface engineering for improved performance.
• Nano-structuring approaches to boost ion transport and active site accessibility.
• Symmetric, asymmetric, and battery type supercapacitors.
• Electrochemical stability and structural robustness under repeated cycling.
• Innovative current collectors, electrolyte engineering, and separators for next-generation devices.
• Scalable and commercially viable fabrication strategies for high-performance supercapacitors.
