3D porous carbon electrodes have attracted significant attention for advancing compressible supercapacitors (SCs) in flexible electronics. The micro- and nanoscale architecture critically influences the mechanical and electrochemical performance of these electrodes. However, achieving a balance between high compressive strength, electrochemical stability, and cost-effective sustainable production remains challenging.

To understand xylan-cellulose interactions in softwood, the adsorption behavior of hexameric softwood xylan proxies with various substitutions was analyzed on the three surfaces of a hexagonal cellulose microfibril. The study found that all surfaces could bind xylan motifs, showing equally high affinity for the hydrophilic (110) and hydrophobic (100) surfaces and significantly lower affinity for the hydrophilic (11̅0) surface. Unsubstituted xylose hexamers had the highest affinity and most ordered adsorption structures, while substitutions generally reduced the affinity and regularity.

The mechanical flexibility and high conductivity of hydrogel electrolytes are crucial for their application in supercapacitors. In this study, we developed hydrogel electrolyte based on lignocellulose nanofibers (LCNFs) through nanofibrillation and self-catalytic gelation in a glycerinum/choline chloride/aluminum chloride hexahydrate (Gly/ChCl/AlCl·6HO) metal-based neutral deep eutectic solvent (DES) system. The lignin-Al self-catalytic mechanism offered an eco-friendly and sustainable method for synthesizing hydrogel electrolytes, while enhancing their ionic conductivity.

Light metal-based nanomaterials are widely used for energy storage due to their high energy density and surface-to-volume ratio. However, their high reactivity is paradoxically both the source of advantageous properties and a hurdle to the fabrication of stable nanostructures. Here, we demonstrate the formation of nanoporous Mg via chemical redox agent-driven dealloying, which ensures minimized surface passivation and results in fine nanostructures with <50 nm of interconnected metallic ligament despite the labile chemical properties of Mg.
