Here, we report a stable Fe-ZrO₂ electrocatalyst for oxygen reduction reaction (ORR) catalysis. Atomically coupled Fe-O-Zr heterointerfaces are formed by embedding Fe nanodots (around 18 nm) into ZrO₂ nanoparticles dispersed in nitrogen doped bubble-like porous carbon nanofibers (PCNFs). In this structure, Fe can share electrons with ZrO₂ to form interfacial coupling Fe-O-Zr bond as a bridge for charge transfer, in which ZrO₂ acts as electron promoter to facilitate electron transfer from Fe to the interface, thereby inhibiting the rapid deactivation of Fe and accelerating the activation and conversion of intermediate adsorbates. As a result, the electrocatalyst with a high loading of Fe (7.96 wt%) achieves a high half-wave potential of 0.868 V, with 95.3% of retained activity after cycling for 39600 s. The ZABs show stable open-circuit voltages and high capacities of 823.9 mA·cm⁻², and can stably run 1560 cycles at 10 mA·cm⁻² with a round-trip efficiency of 51%, exhibiting superior cycling stability.</div></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":"8 ","pages":"Article 100317"},"PeriodicalIF":0.0,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144124184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the consistency difference of series-connected battery packs, a modular hierarchical active equalization method based on inductors is proposed. First, the topology is proposed in combination with the high accuracy of inductor-based equalization, and its working principle and parameter design are analyzed. Second, based on the equalization principle, a matching adaptive equalization control strategy is designed. Again, the equalization performance of the proposed equalization method is analyzed, which shows that the proposed method has the advantages of fast equalization speed, low topological cost and simple control. Finally, an experimental platform for the equalization of a 9-cell series-connected battery pack is established to verify the effectiveness of the proposed equalization method.

These parameters, such as thermal conductivity and specific heat capacity, are crucial for optimizing the performance and safety of the battery. Conventional methods for obtaining these measurements often require expensive and sophisticated laboratory equipment, which limits accessibility and ease of use. An innovative hybrid approach is presented for measuring the thermophysical parameters of the active zone in lithium-ion batteries. This method combines experimental measurements with numerical simulations to determine anisotropic thermal conductivity, specific heat capacity, and the density of the electrode stack. A key aspect of this approach is the use of low-viscosity liquid paraffin to simulate the effects of the electrolyte. The through-plane and in-plane thermal conductivities of both wetted and dry specimens are measured, while the specific heat capacity is approximated numerically. This simple, cost-effective technique eliminates the need for specialized and expensive lab equipment. The through-plane thermal conductivity of the wetted specimen was found to be 2 orders of magnitude greater than that of the dry specimen, while the difference between the in-plane thermal conductivities of the wetted and dry specimens was negligible. The errors in the measured values of through-plane and in-plane thermal conductivities were approximately 4% and 2%, respectively, while the numerically approximated specific heat capacity showed an error of around 2.5%. All measured parameters were found to be within reported ranges. A 3D lumped thermal model incorporating the measured thermophysical parameters was simulated using the commercial software ANSYS Fluent to examine the effects of thermal anisotropy.
