Energetic Landscape of Functionally Modified 2D Nano-ceramics for Energy Storage: Cody Cockreham¹; Xianghui Zhang¹; Gengnan Li¹; Hongwu Xu²; Di Wu¹; ¹Washington State University; ²Los Alamos National Laboratory
    Determining property – thermodynamic relationships by investigating the energetic stability and energetics of surface interactions of nanomaterials provides a way to quantitatively link the effects of the highly variable extrinsic parameters of nano-ceramics to their synthesis conditions. Here, we manipulate the synthesis of two 2D layered nano-ceramic materials, MXene, a family of early transition metal carbides and nitrides, and transition metal-based layered double hydroxides (LDH), to investigate the property – energetic relationships of common 2D layered nanomaterials used in electrochemical energy conversion and storage. By varying the intralayer, composition (LDH) and surface groups (MXene), and interlayer, intercalated and confined species, and quantifying their thermodynamic interactions using a variety of experimental calorimetric methods, we completely characterize the energetic landscape of these materials. Finally, we link our findings with electrochemical performances. This new perspective results in meaningful lessons in design for higher stability and performance nano-ceramics for energy conversion and storage devices.
