Ionothermally synthesized hierarchical porous Schiff-base-type polymeric networks with ultrahigh specific surface area for supercapacitors

Abstract: A hierarchical porous polymeric network (HPPN) with ultrahigh specific surface area up to 2870 m2 g−1 was synthesized via a one-step ionothermal synthesis method without using templates.

“…Figure 6(d) shows the Ragone plot calculated through the GCD data at varying current densities: the energy density of the as-prepared supercapacitor decreases from 7.64 to 4.86 Wh kg −1 , while the power density increases from 0.25 to 5 kW kg −1 . This result implies that the energy density of our HPCN-3 based semi-solid-state symmetrical supercapacitor is below the medium level of the reported supercapacitor devices with doped carbon materials as the electrodes and PVA/H 2 SO 4 gel as the electrolyte [64][65][66][67]. Notably, one supercapacitor device can light up a small LED bulb (the inset picture in figure 6(d)).…”

“…8 In addition, the characteristic peaks of C=N bonds in L and M-L can be found at 1624 and 1209 cm −1 . 43,44 Meanwhile, a new small absorption peak was found at Al-L, Cr-L and Zn-L at 593 cm −1 , 588 cm −1 and 437 cm −1 , respectively. This can be attributed to the stretching vibration of M-N, which is another evidence of coordination bond formation between L and metal ions.…”
