Lithium metal capacitors (LMCs), inheriting the merits of lithium metal batteries with a high energy density and an outstanding power capability comparable to that of supercapacitors (SCs), exhibit tremendous potential for next-generation energy storage systems. However, the application of a Li metal anode i
The energy storage mechanisms of supercapacitors can be mainly classified into two categories [24, [39], [40], [41]].The first mechanism is due to electrostatically accumulating charges at the electrode/electrolyte interfaces, forming two charged layers, as shown in Fig. 4 a, and the resulting supercapacitor is termed an electrical double layer …

This brief presents a dual-band antenna decoupling technique with independent control using composite capacitors. Due to the inherent frequency-selective characteristic of the decoupling structure, the decoupling in one band has almost no effect on that in the other band, so the decoupling in the two bands can be independently controlled simply by …
