This work builds upon prior studies by incorporating a full cell model that accounts for species transport, electrolyte flow, charge transfer, and proton transport within both positive and negative electrodes. PEs are optimized under different depths of discharge (DoD) conditions—5%, 50%, 65%, 90% and 95%—to capture the diverse requirements for reaction kinetics and mass transport under varying reactant concentrations. The optimized structures, featuring interdigitated channels on both electrodes, yield substantial improvements in mass transport and reaction rates compared to unmodified flow-through and interdigitated flow-field configurations. Performance tests, including polarization curves and charge/discharge characteristics, demonstrate superior current density and electrolyte utilization in the optimized flow-through porous electrode (OFT) designs. Among these, the OFT95% (optimized at 95% DoD) performs exceptionally well under low reactant conditions. Despite minor tradeoffs in hydraulic power loss, the optimized structures maintain competitive round-trip efficiency, showing promise for real-world applications. This study provides critical insights into electrode engineering for VRFBs, contributing to the advancement of sustainable energy storage technologies essential for achieving carbon neutrality.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 4","pages":""},"PeriodicalIF":4.7,"publicationDate":"2026-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147683075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The clarification of degradation mechanisms helps in understanding aging phenomena emerging during cycling. This article investigates different electrolytes formulations containing varying amounts fluoroethylene carbonate (FEC) for employment in high voltage applications. Long-term cycling revealed roll over effect occurring for the use of FEC and EC as cosolvents and highest capacity retention for FEC replacing EC. Subsequent post mortem electrolyte analysis by means of high-performance liquid chromatography coupled to quadrupole time of flight analyzer revealed the formation of FEC related degradation products. FEC undergoes subtraction of fluoride to form in situ VC which then continuously reacts with other electrolyte components.

In this study, the electrochemical behavior and degradation mechanisms of full cells based on LiFePO4 and TiS2 electrodes are systematically investigated in 21 m LiTFSI electrolyte.

Through strategic boron (B) doping at the oxygen framework, a reconfiguration of local bonding environments is observed, which mitigates transition-metal migration and stabilizes the layered lattice during high-voltage cycling. Electrochemical analyses reveal a trade-off between enhanced voltage retention and marginal capacity suppression at elevated doping levels, attributed to altered Na+ diffusion pathways and phase evolution dynamics. Complementary structural and spectroscopic studies indicate suppressed phase transitions due to anionic redox, underscoring the dual role of boron in reinforcing both electronic transport and structural resilience.

High-capacity anode materials are one of the bottlenecks limiting the improvement of energy density of SIBs, while tuning the closed porous structure is the most efficient approach to boost the plateau capacity. Unfortunately, simple and practical closed-pore-forming strategies remain scarce. Herein, a transition metal oxide catalytic strategy to prepare closed-pore-rich hard carbon anode for the first time while simultaneously transforming the catalyst into layered oxide cathode is reported. The abundant closed-pore structure provides an augmented array of sites for sodium ion storage, thereby contributing to a heightened plateau capacity and Coulombic efficiency. Hence, the obtained anode delivers a reversible capacity of 301.6 mAh g−1 with a high initial coulombic efficiency of 92.3%. Note that a capacity retention of 98.4% is achieved after 300 cycles. In particular, a full cell constructed by the above closed-pore-rich hard carbon anode and layered oxide cathode demonstrates favorable energy density and cycling stability.

In liquid electrolytes, key approaches are analyzed, including high-concentration/localized formulations, fluorinated components, and functional additives designed to form robust and stable solid electrolyte interphases. For solid-state electrolytes, advances in polymer, inorganic, and composite systems are surveyed, aimed at enhancing ionic conductivity while mechanically suppressing dendrites.

Electrochemical impedance spectroscopy analyses show that a less resistive and more effective solid electrolyte interphase (SEI) forms upon prelithiation which also benefits the charge transfer at the SiGr electrode. Scanning electron microscopy images show a thicker interphase layer with less interstitial porosity on the prelithiated SiGr electrodes and a thinner cathode electrolyte interphase on NMC-811 electrode as a result of the lower average cathode potential attained throughout cycling, in comparison with the cells without prelithiation. A more diverse SEI layer, richer in beneficial components such as LiF, is promoted by the prelithiation method as shown by X-ray photoelectron spectroscopy with a sputtering depth of 100 nm.
