To synthesize the hybrid copper chloride perovskite (C6H5CH2NH3)2[CuCl4] and assess its viability and structural stability as an electrode material in lithium-ion batteries.
Synthesized the organic–inorganic layered perovskite (C6H5CH2NH3)2[CuCl4] and confirmed its structure using X-ray diffraction, scanning electron microscopy, and infrared spectroscopy.
Evaluated battery performance using cyclic voltammetry and galvanostatic charge–discharge cycling, followed by postmortem X-ray diffraction to identify structural alterations.
The electrode achieved an initial specific capacity of 114 mAh g−1 at 20 mA g−1 and sustained approximately 99% coulombic efficiency after 100 cycles.
Postmortem XRD revealed partial disappearance of initial diffraction peaks alongside retained peaks, indicating partial structural breakdown during copper redox cycling.
