Citric Acid Enable Morphological Optimization of Ni 3 (PO 4 ) 2 Next Generation High Performance Hybrid Supercapacitors

Key Points

• The research aims to optimize the morphology of nickel phosphate to enhance the performance of hybrid supercapacitors.
• Synthesis of nickel phosphate (Ni 3 (PO 4 ) 2 ) using a hydrothermal process.
• Citric acid was used as a treatment during the synthesis to achieve a hierarchical architecture.
• The cabbage-like hierarchical structure improved performance metrics of supercapacitors.
• Enhanced conductivity and charge storage capacity were observed due to the optimized morphology.
