Expert Talk on MXenes for Next Generation Energy Storage Device

MXenes have emerged as a promising paradigm in high-rate energy storage devices. Dr Narendra Kurra, renowned academician and scholar in the field of Chemistry will be expounding on Non-Aqueous Electrochemistry of Titanium Carbide (MXene) for Next Generation Energy Storage Devices in a session organised by the Department of Chemistry on June 30, 2023. Join the session to learn exciting details on the subject!

Abstract

MXenes – an emerging class of two-dimensional (2D) transition metal carbides, nitrides, and carbonitrides – have shown promise towards development of high-rate energy storage devices.[1] MXenes are usually produced by top-down synthesis, namely wet chemical extraction of ‘A’ atomic layers from the layered ternary carbide precursors, such as MAX phases. The available 2D gallery spaces for intercalation of ions, accessible redox sites at the transition metal oxide-like surface, and metallic conductivity make MXenes promising materials for high-rate capacitive energy storage applications.[2,3] However, intrinsic hydrophilic surface chemistry of MXenes may not be suitable when interfacing with non-aqueous electrolyte ions. The electrochemical storage of non-aqueous cations across Ti3C2Tx MXene galleries and the role of solvation effects and surface chemistry will be discussed. Besides the role of Ti3C2Tx MXenes as active charge storage materials, metallicity (electronic conductivity beyond 20,000 S/cm) enables current collector-free fabrication of energy storage devices,[4] substantially decreasing their size and weight.
