Abstract Bacterial cellulose (BC) is produced via the fermentation of various microorganisms. It has an interconnected 3D porous network structure, strong water‐locking ability, high mechanical strength, chemical stability, anti‐shrinkage properties, renewability, biodegradability, and a low cost. BC‐based materials their derivatives have been utilized to fabricate advanced functional for electrochemical energy storage devices flexible electronics. This review summarizes recent progress in development BC‐related devices. The origin, components, microstructure BC are discussed, followed by advantages using applications. Then, material design strategies terms solid electrolytes, binders, separators, as well BC‐derived carbon nanofibers electroactive discussed. Finally, short conclusion outlook regarding current challenges future research opportunities related next‐generation suggestions proposed.

Poly(ethylene oxide) (PEO) has been widely studied as an electrolyte owing to its excellent lithium compatibility and good film-forming properties. However, electrochemical performance at room temperature remains a significant challenge due low ionic conductivity, narrow window, continuous decomposition. Herein, we prepare multifunctional polar polymer optimize PEO's properties cycling stability. crystallinity is disrupted with the addition of polymer, amorphous segments create more transfer pathways for Li-ion. More importantly, groups enhance Li-ion transference number by facilitating salt dissociation through Lewis acid–base interactions weaken coordination between ether oxygen, thereby expediting migration. In addition, trifluoromethyl promote TFSI– defluorination, forming LiF-rich solid interphase layers that prevent decomposition PEO. The resulting composite exhibits conductivity (2.06 × 10–4 S cm–1) (0.30) outstanding voltage (4.9 V). assembled symmetric battery could perform stably 620 h 0.1 mA cm–2. Li||LiFePO4 cells exhibit capacity retention (87.81%) Coulombic efficiency (100.0%) 0.5 C over 700 cycles.

Electrochemical generation of hydrogen peroxide (H2O2) through the two-electron oxygen reduction reaction (2e– ORR) represents a sustainable development strategy for bulk H2O2 manufacturing, yet crafting efficient catalysts remains substantial challenge. Carbon materials are particularly appealing as electrochemical catalysts, owing to their diverse nanostructures and adjustable attributes. Nonetheless, lack structure–property understanding has hindered progression metal-free carbon electrocatalysts. In this study, we fabricated porous with abundant edge sulfhydryl groups (−SH) determined that 2e– ORR performance is roughly proportional −SH content, outperforming reported in aspects such selectivity (90–98% over broad potential 0.30–0.70 V vs RHE) stability (maintaining 90% during 12 h testing) measured alkaline solution rotating ring-disk electrode setup. Furthermore, flow cell setup, both production rate (2910 mmol gcatalyst–1 h–1) Faraday efficiency (over 80%) surpass most carbon- metal-based Consequently, research illuminates straightforward pathway design specific sulfur configurations carbon-based high-selectivity production.

Abstract Natural biomass-derived carbon material is one promising alternative to traditional graphene-based catalyst for oxygen electrocatalysis. However, their electrocatalytic performance were constrained by the limited modulating strategy. Herein, using N-doped commercial coconut shell-derived activated (AC) as model, controllably enhanced sp 2 -C domains, through an flash Joule heating process, effectively improve edge defect density and overall graphitization degree of AC catalyst, which tunes electronic structure N configurations accelerates electron transfer, leading excellent reduction reaction (half-wave potential 0.884 V RHE , equivalent 20% Pt/C, with a higher kinetic current 5.88 mA cm −2 ) evolution activity (overpotential 295 mV at 10 ). In Zn-air battery, shows outstanding cycle stability (over 1200 h) peak power 121 mW surpassing Pt/C RuO catalysts. Density functional theory simulation reveals that catalytic arises from axial regulation local domains. This work establishes robust strategy domain modulation, offering broad applicability in natural biomass-based catalysts
