  报告题目：The Evolution of Ionic Network in Electrochemical Capacitive Materials: from Precast to Self-Adaptive

Electrochemical capacitors (ECs) provide appealing energy storage solutions, because of their higher power density, better safety and greater life span relative to lithium batteries. The traditional electrode materials for ECs are porous materials. Porous carbons, such as activated carbon, carbon nanotubes, mesoporous carbons, and graphene, are being widely used for ECs for fundamental research and industrial application. A long-lasting question, maybe also a challenge, is the rational design and control fabrication of the porous texture of carbons for the purpose of improving the EC performance via facilitating the inner-pore mass transport. Despite the great achievements in the past decades, most of the porous materials possess pre-designed and precast porous networks that may not possess the right pore size, symmetry, wettability, etc. for ECs with various configurations.

The search of ‘smart’ materials that can automatically adapt with the electrochemical capacitive environment is in its infancy. The solvent swelling of two-dimensional (2D) materials (such as graphene, MXene, etc.)has shown great impact for transformative technological advances for ECs via the supramolecular engineering of the flexible 2D ionic spaces.

This lecture will firstly review the history of the design of precast ionic network in porous carbons for ECs, and then discuss the latest progress in the synthesis of self-adaptive ‘liquid-in-solid’ 2D supramolecular clays for ECs.
