Abstract
This work aims to prepare perovskite zinc stannate (ZnSnO3) by the sol-gel method and to study the electrochemical properties. This performance improves by adding different percentages of naturally prepared activated carbon from pomegranate peels. ZnSnO3 is considered an attractive cathode material for energy storage, which shows a specific capacitance of 115 F g‒1 at 1 A g‒1, while the optimum added percentage of the activated carbon is 5%AC+95%ZnSnO3, which exhibits 312.5 F g‒1 at the same current density, which considered about three times more than that of the ZnSnO3, with capacitance retention of 66% after 2000 cycles at the current density of 10 A g‒1. The practical hybrid device shows a specific capacitance value of 61.6 F g‒1 at 1 A g‒1, the specific energy of 22 Wh kg‒1, and specific power of 1077 W kg‒1 with capacitance retention of 50% of the initial capacitance after 2000 cycles at a current density of 10 A g-1. As a result, ZnSnO3 and its composite with cheap and natural materials are considered promising supercapacitor electrodes.
