In lithium–polymer batteries, the electrolyte is an essential component that plays a crucial role in ion transport and has substantial impact on battery’s overall performance, stability, efficiency. This article presents detailed study developing nanostructured composite polymer electrolytes (NCPEs), prepared using solvent casting technique. The materials selected for this investigation include poly(vinyl chloride) (PVC) as host polymer, lithium bromide (LiBr) salt, silica (SiO2) nanofiller. addition of nano-SiO2 dramatically enhanced ionic conductivity electrolytes, with highest value 6.2 × 10−5 Scm−1 observed sample containing 7.5 wt% nano-SiO2. improvement attributed to increased amorphicity resulting from interactions between filler components. A structural analysis NCPEs X-ray diffraction revealed presence both crystalline amorphous phases, further validating transport. Additionally, thermal stability was found be excellent, withstanding temperatures up 334 °C, thereby reinforcing their potential application batteries. work explores electrochemical performance fabricated lithium-ion-conducting primary cell (Zn + ZnSO4·7H2O|PVC: LiBr: SiO2|PbO2 V2O5), which demonstrated open circuit voltage 2.15 V. discharge characteristics were thoroughly studied, showcasing promising these NCPEs. With support superior morphological electrical properties, as-prepared offer effective pathway future advancements battery technology, making them highly viable candidate energy storage solutions.

The Role of Dispersion Solvent Composition in Pemfc Electrodes: Performance and Durability Insights

Опубликована: Янв. 1, 2025

A profound understanding of the interplay between catalyst ink properties, layer (CL) structure, and resulting cell performance longevity is crucial for advancement proton exchange membrane fuel (PEMFC) technology. This study systematically examines how solvent composition in influences CL structure its subsequent effects on PEMFC durability. Using a scalable slot-die coating technique, we fabricated electrodes with varying water-to-alcohol (W/A) ratios ink. Notably, derived from an W/A ratio 3:1 exhibited superior initial performance, reaching peak voltage 0.824 V at 100 mA/cm2 0.588 2800 mA/cm2. enhancement kinetic activity oxygen mass transport attributed to smallest agglomerates more uniform, continuous distribution ionomer within CL. In terms durability, electrode prepared 2:1 best results, showing only 23 mV drop 0.8 A/cm2 after 30,000 accelerated stress cycles. enhanced stability linked crack-free morphology relatively low coverage W/A=2:1 CL, which contribute structural robustness.
