6 FAQs about [Porous Ceramic Capacitors]

What is the density of porous ceramics?

There was an increase in the bulk density of porous ceramics from 4.77 to 5.55 g/cm 3, as well as an increase in porosity from 7 to 20%, and the density of the ceramics decreased with the increase in the content of the pore maker.

Which ceramic electrode has the highest specific capacitance?

Finally, the NiFe 2 O 4 ceramic prepared by the sol-gel route exhibited the highest specific capacitance of 97.5 F/g due to the well-balanced micro- and mesoporosity of the electrode ( Fig. 3 b). The electrode showed stable electrochemical performance even after 100 CV cycles.

Can porous carbon be used as a supercapacitor electrode?

Not only does the porous carbon material have a high SSA, but it also has the high electrical conductivity that comes with a highly graphitised structure. This is something that is difficult to achieve with other methods. In this review, we also list the applications of porous carbons as supercapacitor electrodes in recent years.

What is a specific capacitance of a ceramic electrolyte?

The as-synthesized ceramic exhibited a specific capacitance of 0.13 F/cm at 2 mV/s since the porous ceramic structure increased the contact area between the electrode and the solid electrolyte. Liao et al. incorporated SWCNTs with the LATP ceramic electrolyte [ 158 ].

What is the capacitance of carbon-filled layered ceramics?

Carbon-filled layered ceramics show a large capacitance of 0.13 F cm −1 at a low scan rate of 2 mV s −1. The large capacitance for carbon-filled layered ceramics is due to the enhanced contact area between the electrode and solid electrolyte in the porous structure.

Is ceramic a good electrode material for supercapacitors?

Among them, the development of ceramic materials is no exception. Importantly, the corrosion resistance, high-temperature resistance, radiation resistance, and thermal shock resistance of ceramic material still provide the possibility and advantages for it to become an electrode material for supercapacitors.
