“…Representative stress–strain curves can be seen in Figure a, while Table S2 summarizes the main characteristic parameters. The glass microfiber separator presents a stiff and brittle character, with a modulus of 1470 ± 120 MPa and ε b of ∼5.8 ± 0.1% . On the contrary, as schematized in Figure b, LSKL–chitosan and LS–chitosan GPEs show a semi-ductile behavior characterized by E values ranging from 55 ± 4 to 940 ± 63 MPa and ε b values of 14.1 ± 0.2 to 43.9 ± 21.1% (Figure c,d).…”

Electrochemical energy storage technologies offer means to transition toward a decarbonized society and carbon neutrality by 2050. Compared to conventional lithium-ion batteries, aqueous zinc-ion chemistries do not require scarce materials or toxic and flammable organic-based electrolytes to function, making them favorable contenders in the scenario of intensifying climate change and supply chain crisis. However, environmentally benign and bio-based materials are needed to substitute fossil-based battery materials. Accordingly, this work taps into the possibilities of lignin together with chitosan to form gel polymer electrolytes (GPEs) for zinc-ion chemistries. A simple fabrication process enabling free-standing sodium lignosulfonate− chitosan and micellar lignosulfonate−kraft lignin−chitosan GPEs with diameters exceeding 80 mm is developed. The GPEs combine tensile strength with ductility, reaching Young's moduli of 55 ± 4 to 940 ± 63 MPa and elongations at break of 14.1 ± 0.2 to 43.9 ± 21.1%. Competitive ionic conductivities ranging from 3.8 to 18.6 mS cm −1 and electrochemical stability windows of up to +2.2 V vs Zn 2+ /Zn were observed. Given the improved interfacial adhesion of the GPEs with metallic Zn promoted by the anionic groups of the lignosulfonate, a stable cycling of the Zn anode is obtained. As a result, GPEs can operate at 5000 μA cm −2 with no short-circuit and Coulombic efficiencies above 99.7%, outperforming conventional separator−liquid electrolyte configurations such as the glass microfiber separator soaked into 2 M ZnSO 4 aqueous electrolyte, which short-circuits after 100 μA cm −2 . This work demonstrates the potential of underutilized biorefinery side-streams and marine waste as electrolytes in the battery field, opening new alternatives in the sustainable energy storage landscape beyond LIBs.

“…The main reason is attributed to the presence of polar -COO − groups, which can inhibit the transport of ClO 4 − in the electrolyte but favor for the passage of Na + .

A Sodiophilic Amyloid Fibril Modified Separator for Dendrite‐Free Sodium‐Metal Batteries

et al. 2023

Sodium (Na) batteries are being considered as prospective candidates for the next generation of secondary batteries in contrast to lithium‐based batteries, due to their high raw material abundance, low cost, and sustainability. However, the unfavorable growth of Na metal deposition and severe interfacial reactions have prevented their large‐scale applications. Here we propose a vacuum filtration strategy through amyloid fibril modified glass fiber separators to address these issues. The modified symmetric cell can be cycled for 1800 h, surpassing the performance of previously reported Na‐based electrodes under an ester‐based electrolyte. Moreover, the Na/ Na3V2(PO4)3 full cell with a sodiophilic amyloid fibril modified separator exhibits a capacity retention of 87.13% even after 1000 cycles. Both experimental and theoretical results show sodiophilic amyloid fibril homogenizes electric field and Na ion concentration, fundamentally inhibiting dendrite formation. Simultaneously, the glutamine amino acids in the amyloid fibril have the highest adsorption energy for Na, resulting in the formation of a stable Na3N and NaNxOy‐rich solid electrolyte interface film on the anode during cycling. This work provides not only a possible pathway to solve dendrite problem in metal batteries using environmental‐friendly biomacromolecular materials, but also a new direction for expanding biomaterial applications.This article is protected by copyright.

Cellulose membranes have eco-friendly, renewable, and cost-effective features, but they lack satisfactory cycle stability as a sustainable separator for batteries. In this study, a two-step method was employed to prepare a sandwich-like composite membrane of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP)/cellulose/ PVDF-HFP (PCP). The method involved first dissolving and regenerating a cellulose membrane and then electrospinning PVDF-HFP on its surface. The resulting PCP composite membrane exhibits excellent properties such as high porosity (60.71%), good tensile strength (4.8 MPa), and thermal stability up to 160 °C. It also has exceptional electrolyte uptake properties (710.81 wt.%), low interfacial resistance (241.39 Ω), and high ionic conductivity (0.73 mS/cm) compared to commercial polypropylene (PP) separators (1121.4 Ω and 0.26 mS/cm). Additionally, the rate capability (163.2 mAh/g) and cycling performance (98.11% after 100 cycles at 0.5 C) of the PCP composite membrane are superior to those of PP separators. These results demonstrate that the PCP composite membrane has potential as a promising separator for high-powered, secure lithium-ion batteries.
