Abstract As the most abundant renewable aromatic biopolymer resource on Earth, lignin has become a cutting‐edge research hotspot in clean photocatalysis, thanks to distinct highest occupied molecular‐orbital and lowest unoccupied energy levels driven by major β‐O‐4 linked bonds. However, complex spatial architecture of functional groups, represented benzene rings 3D intertwined macromolecular chains lignin, challenge enhancing carrier separation efficiency remain persistent obstacles hindering development lignin‐based photocatalysts. Herein, strategy constructing nanosphere‐graphene oxide heterointerfaces (EL‐GO) is proposed comprehensively enhance efficacy groups facilitate photoelectron migration modes. The recombination time light‐excited photoelectrons effectively prolonged π‐π interactions between “Donor site” “Acceptor regions, along with directional EL GO. photocatalytic H 2 O production using EL‐GO significantly enhanced under protective mechanism To assess its potential, prospect estimation lake containing various pollutants metal ions was conducted, simulating real water conditions. This pioneering engineering effort aims curb excessive consumption fossil fuels explore green applications thereby “carbon‐neutral” feedstock system.

Using Recycled Materials in a Novel Dual Binder System for Hard Carbon Anodes: Closing the Loop Toward Sustainable Li‐/Na‐ion Batteries

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 3, 2025

Abstract Hard carbon (HC) has significant potential as anode material for both Li‐ion and Na‐ion batteries; however, its commercialization is hindered by challenges such poor rate capability low initial Coulombic efficiency (ICE). Although polymeric binders constitute a small fraction of the overall electrode composition, they play crucial role in influencing electrochemical performance. Here, this study introduces novel dual composite binder, combining polyacrylic acid (PAA) polyvinyl butyral (PVB). The interaction between COOH groups PAA OH PVB via hydrogen bonding prompts cohesive polymer network resulting electrodes exhibiting superior high ICE laboratory‐scale cells, surpassing performance those with other tested. After optimizing formulations using commercial PVB, we demonstrate first time use recycled sourced from laminated glass waste, to address lack end‐of‐life programs material, which often ends up landfills. Repurposing waste battery applications tackles management issues contributes innovative development advanced, green materials circular economy approach, thus paving way waste‐to‐energy solutions high‐performance socio‐economical environmental benefits.

Published: April 1, 2025

Hard carbon (HC) exhibits great potential as a promising candidate for sodium-ion batteries owing to its inherent advantages. However, the main challenges in utilizing HC stem from low initial coulombic efficiency (ICE) and poor rate performance caused by excessive surface defects. In this study, an effective strategy of employing alkali lignin (AL) is proposed, derived pulp waste, binder create uniform inorganically enriched solid electrolyte interface. AL can modify defects through strong π-π interactions between aromatic ring HC, while ingeniously grafting abundant active ─OH ─COOH groups onto electrode surface. The force salts facilitates formation ultra-thin NaF-rich interface (SEI) layer (10 nm), thereby achieving exceptional ICE 91%. Furthermore, electrochemical activity, enables anode exhibit increasing slope capacity during cycling, compensating decay at high current densities. Consequently, when assembled into full battery configuration, excellent achieved with reversible 282 mAh g-1 even density 5A g-1.
