Heterostructured MXene and g-C3N4 for high-rate lithium intercalation

A critical limitation to conventional electrochemical double-layer capacitors is their low energy densities. This has triggered significant interest in developing new pseudocapacitive materials, which utilize faradaic mechanisms to increase their energy densities. In this work, graphitic carbon nitride (g-C3N4) and Ti3C2Tx MXene are hybridized to form a unique two-dimensional (2D) heterostructure, which delivers remarkable pseudocapacitive...
