K. Pious, M. L. Lekshmi, Chinnadurai Muthu, R. B. Rakhi, Chakkooth VijayakumarSymmetrical electrochemical capacitors are attracting immense attention
because of their fast charging–discharging ability, high energy
density, and low cost of production. The current research in this
area is mainly focused on exploring novel low-cost electrode materials
with higher energy and power densities. In the present work, we fabricated
an electrochemical double-layer capacitor using methylammonium bismuth
iodide (CH3NH3)3Bi2I9, a lead-free, zero-dimensional hybrid perovskite material.
A maximum areal capacitance of 5.5 mF/cm2 was obtained,
and the device retained 84.8% of its initial maximum capacitance even
after 10 000 charge–discharge cycles. Impedance spectroscopy
measurements revealed that the active layer provides a high surface
area for the electrolyte to access. As a result, the charge transport
resistance is reasonably low, which is advantageous for delivering
excellent performance.
