Ordered porous and uniform electric-field-strength micro-supercapacitors by 3D printing based on liquid-crystal V2O5 nanowires compositing carbon nanomaterials

Ethanol‐Induced Ni2+‐Intercalated Cobalt Organic Frameworks on Vanadium Pentoxide for Synergistically Enhancing the Performance of 3D‐Printed Micro‐Supercapacitors

“…[ 10,11 ] As a typical EESS, supercapacitors display a fast charge transfer and charging ability. [ 12 ] MOF nanocomposites formed using metal nanoparticles, [ 13 ] carbon‐based materials, [ 14 ] metal oxides, [ 15 ] and hydroxyl oxides [ 16 ] are promising materials for fabricating supercapacitors. [ 17,18 ]…”

“…[34][35][36] V 2 O 5 NWs are widely used in MSCs and other applications because of their abundance, multiple oxidation states, low cost, economic viability, and high specific capacity. [12,37] However, the low conductivity and low ion-diffusion rate limit their applications. Therefore, further modifications of these nanocomposites are required to improve their electrochemical performance.…”

Anisotropic Nanomaterial Liquid Crystals: From Fiber Spinning to Additive Manufacturing

“…Similarly, Zhao et al used V 2 O 5 /CNT/GO dispersions to create multifunctional inks in which the V 2 O 5 drove liquid crystalline phase behavior and served as the active material, the CNT created a conductive network, and GO served as a binder that limited V 2 O 5 ’s mobility. By tuning the relative ratios of the materials, different nanoscale structures within the print could be achieved . Both of these works inspire additional research on multishape, multimaterial systems by demonstrating the ability to precisely control the structure through careful consideration of the composition, relative size ratios, colloidal interactions, and shear effects.…”

“…By tuning the relative ratios of the materials, different nanoscale structures within the print could be achieved. 34 Both of these works inspire additional research on multishape, multimaterial systems by demonstrating the ability to precisely control the structure through careful consideration of the composition, relative size ratios, colloidal interactions, and shear effects. In the past 20 years, nanomaterial liquid crystal science has been rediscovered and extended through the production of a broad array of 1D and 2D nanomaterials in quantities sufficient for rheology, phase behavior, and manufacturing studies.…”
