Abstract: The development of efficient electrochemical energy storage (EES) devices is an important sustainability issue to realize green electrical grids. The metal carbide/nitride nanosheets termed MXene discovered in 2011 are a promising class of electrode materials for advanced EES devices because of their compositional versatility for materials exploration, high electrical conductivity for high current charge, and a layered structure of stacked nanosheets for ultrafast ion intercalation. However, general design strategies of MXenes for EES applications have not been established because of the limited understanding of the electrochemical mechanisms of MXenes. In this talk, we will present our current understandings of the MXene electrodes, as well as their applications to some EES devices such as sodium-ion batteries, lithium-ion batteries, and aqueous hybrid capacitors.[1-5] References: [1] X.
