The overall performance of hybrid supercapacitor is dependent on both electrodes as well as electrolyte material. It is important to choose the proper type of electrolyte for electrode materials for betterment in the overall performance of hybrid supercapacitor. The approaches to hybrid supercapacitors are discussed in Section 4. 3.
For instance, Park et al. [ 15] used chemically cross-linked lignin hydrogel electrolytes to fabricate all-lignin-based flexible supercapacitors.
The wide-ranging degree of cycling, the substantial delusion of the active material, the termination of electrode material and current collector leads to high resistance in the hybrid supercapacitor . These limiting factors results in unfastening, diminishing and decent of material.
The prepared supercapacitor (SC-Lig/SPI-50%) with the hydrogel electrolyte showed a remarkable electric double layer property with a specific capacitance up to 150.80 F g −1 and an energy density up to 4.94 W h kg −1 at 0.5A g −1. Through the bending experiments at different angles, it was proved that the supercapacitor exhibited good flexibility.
Considering the manufacturing consequence and the ease of unison, the asymmetric hybrid supercapacitors use the aqueous electrolytes possessing uplifted ionic conductivity , . Electrolytes play a pivotal role in supercapacitor performance.
Sealants perform an auxiliary role in the hybrid supercapacitor assembly avoiding performance loss . Sealant functions as a blockage to the outside contaminants like air, water, chemicals etc. These contaminations can bring about electrolyte degeneracy and surface oxidation on electrodes.
