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
The electrochemical enhancement of polyaniline (PANI) by adding nanomaterials is closely related with the dispersion state of the nanomaterials in PANI. Herein, we demonstrate the fabrication of well-mixed PANI/nanomaterials composites through solid-phase exfoliation and subsequent in-situ polymerization. Bulk molybdenum disulfide (MoS 2 ) or carbon nanotube (CNT) bundles were firstly ball-milled in the presence of calcium lignosulphonate to provide lignosulfonate (LS) noncovalently functionalized MoS 2 nanosheets or CNTs, which were then used as skeletons for in-situ polymerization of aniline. The resulted nanocomposites exhibited enhanced electrochemical properties as compared with pure PANI. Typically, the ternary composite PANI/MoS 2 -LS/CNT-LS delivered a specific capacitance of 458.9 F/g, a 63% improvement than PANI at 1 A/g in a three-electrode system. Furthermore, excellent cycle stability (86% capacitance retention after 10, 000 charge-discharge cycles) and high specific energy (10.9 Wh/kg at specific power of 265.3 W/kg) were obtained in a coin-type symmetric supercapacitor. The study provides an efficient and facile approach for fabrication of conductive polymer/nanomaterials composite for supercapacitors with good stability and performance.
