Metric Options: CountsSelecting 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
Lithium extraction from brines by electrochemical De-intercalation/Intercalation method with LiFePO 4 as host materials has attracted extensive attention, but the ionic transport properties and rate-determining step of this process are not fully understood. Therefore, to address this knowledge gap, we study the electrode process kinetics of LiFePO 4 /Li 1- x FePO 4 (0 < x < 1) in brines by electrochemical impedance spectroscopy. The results reveal that the diffusion of Li + in electrode is the rate-determining step, the apparent diffusion coefficient D Li shows a trend of first increasing and then decreasing with the increase of electrode coating density, and the maximum value is obtained as 2.23 × 10 −11 cm −2 ·s −1 at 55 mg·cm −2. The charge transfer resistance R ct and Warburg impedance Z ω decrease with increasing temperature and do not change significantly with Li + concentration, but Mg 2+ has an inhibitory effect on Li + charge exchange. Furthermore, the Li + charge transfer at electrode/solution interface is differentiated for different de-lithiated Li 1- x FePO 4 electrodes, the R ct reaches a minimum around Li 0.3 FePO 4. The diffusion of other competing cations is more difficult than Li + in electrodes, which gives theoretical support for selective lithium extraction from brines from a kinetic point of view.
