Summary

In this plenary talk, Prof. Yury Gogotsi presents an overview of new 2D materials, particularly MXenes, and their applications in electrical energy storage and harvesting. He begins by introducing the family of 2D materials, highlighting graphene as the first discovered, and then focuses on MXenes, which are transition metal carbides and nitrides. He explains their unique properties, such as high metallic conductivity, hydrophilic surfaces, and ability to form stable colloidal solutions. Gogotsi discusses various synthesis methods, including selective etching of MAX phases, and demonstrates how MXenes can be intercalated with ions and molecules, leading to tunable properties. He shows applications in supercapacitors, batteries, sensors, and energy harvesting devices, including triboelectric nanogenerators. He emphasizes the potential of MXenes for flexible and wearable electronics. The talk concludes with a call for further research and points to review articles for more details.
