However, its rate performance and cycle life are limited by low charge conduction and Jahn-Teller distortion of Mn³⁺. To address these issues, this study employed radio-frequency magnetron sputtering to deposit LiPON, ZnO, and Li₃PO₄ films on LMFP electrodes for comparison. The results demonstrate that the cross-linked network structure formed by nitrogen bidentate and tridentate bonds in LiPON enhances ionic conductivity and interfacial stability. Increasing the LiPON coating layer to 2.4 nm resulted in optimal electrochemical performance of the LiMn_0.8Fe_0.2PO₄ cathodes. The initial discharge capacity was 156.9 mAh g^-1 at a rate of 0.1C. The capacities measured during multi-rate charge-discharge experiments at rates ranging from 0.1C to 5C were 147.8 mAh g^-1, 141.2 mAh g^-1, and 122.7 mAh g^-1 at 1C, 2C, and 5C, respectively. There was very little capacity loss when the rate was brought back to 0.1C. Capacity retention rose from 88.0% to 95.7% after 100 cycles at 0.5C. LMFP-LiPON materials have better transition metal states close to the Fermi level and lower band gaps, according to density functional theory (DFT) simulations. In addition to increasing electronic conductivity, accelerating lithium-ion transport, and improving corrosion resistance, these changes significantly reduce the Li migration barrier. The approach offers a strong and adaptable lever for designing lithium-ion batteries of the future.</div></div>","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"557 ","pages":"Article 148476"},"PeriodicalIF":5.6,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147386919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The CPBA dopants covalently immobilized on PVA chains act as anchoring sites, promoting the dispersed growth of polypyrrole (PPy) within the 3D hydrogel network. The resulting PPy@PVA-CPBA electrode with an interpenetrating network structure shows evidently enhanced electrochemical performance compared to PPy/PVA and PPy electrodes.

These performance metrics are significantly higher than those of the PPy/PVA SC as a control. This work demonstrates that the developed PVA-CPBA/GP current collector not only promotes the highly efficient utilization of PPy, enhancing the capacitive performance and cycling stability of the SC, but also enables the construction of a separator-free back-to-back flexible SC, thereby improving its mechanical deformation stability.

Flexible carbon-based electrodes offer promising conductivity, lightness, strength, durability, high surface area, porosity and flexibility. Carbon nanotubes decorated with indium oxide prepared by hydrothermal treatment serve as a flexible photoelectrode that integrates both photoactive and energy storage functionalities in LDSCs. The In₂O₃@CNT electrode significantly improves the electrochemical performance compared to pure In₂O₃ and bare CNTs due to the superior electrical conductivity and larger specific surface area. This improvement is due to the synergistic integration of In₂O₃ with carbon nanotubes, which optimize the charge transport and accessibility of the active sites. Consequently, the optimized In₂O₃@CNT electrode delivered a high capacitance of 0.9 mAh/cm² at a current density of 0.08 mA/cm². Under illumination, the specific capacitance of the electrode reached 1.4 mAh/cm², which corresponds to a 1.55-fold increase compared to conditions in the dark. The device showed exceptional flexibility when assembled into a flexible symmetrical LDSC with a sandwich structure. It achieved a specific capacitance of 1.2 mAh/cm², an energy density of 1.77 mWh/cm² and a power density of 53.15 mW/cm². Light-assisted operation resulted in a remarkable increase in specific capacitance compared to dark conditions, suggesting that charges generated by light increase conductivity and accelerate charge transfer processes. In addition, the effects of simultaneous double-sided illumination on the characterization of this device were evaluated, with the results indicating that the capacitance under double-sided illumination exceeds that under single-sided illumination.

In this study, graphene aerogel hybrid materials (CGA and PCGA) were prepared via diverse doping strategies, and the impacts of CNT doping and PDA functionalization on GA performance enhancement were systematically compared. The results revealed that the polydopamine-modified carbon nanotube-graphene hybrid aerogel (PCGA) exhibits exceptional potential as a high-performance MFC anode, owing to its micron-scale hierarchical porous structure, abundant nitrogen-containing active sites, outstanding electrochemical activity, and enhanced biocompatibility.
