Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Microbial fuel cells (MFCs) are electrochemical electricity generation devices that use microorganisms to degrade organic matter to produce electrical energy. However, conventional MFCs cannot store power efficiently, limiting their widespread use. In this study, a two-step hydrothermal method was used to prepare a CF/NiO/Fe3O4 capacitive composite anode by directly growing NiO on a carbon felt substrate as a metal framework to support the in-situ growth of Fe3O4. The power generation and energy storage performance of MFCs constructed with a CF/NiO/Fe3O4 anode was significantly improved, reaching a maximum power density of 9.29 W/m3, which was 1.54 times higher than with a CF/NiO anode. After charging/discharging for 60 min, the total charge of the CF/NiO/Fe3O4 anode was 8532.07C /m2, which was 1868.82 C/m2 higher than that of the CF/NiO anode. High-throughput sequencing results showed that the content of electricity-producing bacteria on the CF/NiO/Fe3O4 anode surface reached 86.03%, which was higher than that on CF/NiO anode surface. The application of capacitive materials in MFCs would allow the constructed MFCs to generate and store bioelectricity simultaneously.
