“…All binder-free electrodes showed peaks at 1020 and 1065 cm −1 attributed to the symmetric stretching vibration of P-O bond. 81,82 The peaks at 1410 and 1555 cm −1 corresponded to the stretching vibration of P=O bond. 83 These peaks verified the presence of phosphate-based electrode material on the nickel foam.…”

A binder-free nickel-copper phosphate battery-type electrode was fabricated using a microwave-assisted hydrothermal technique. The fabrication process was optimized with Design of Experiment (DoE) software and then validated experimentally. The electrode made at 90°C for 12.5 minutes, with a Ni:Cu precursor ratio of 3:1, had the highest specific capacity. The experimental specific capacity of the optimized nickel-copper phosphate (Ni3-Cu-P) binder-free electrode was 96.2% of the theoretical value predicted by the software, which was within 10% error. Moreover, the growth of amorphous Ni3-Cu-P electrode material with irregular microspheres of small size was observed on the surface of nickel foam. These amorphous microspherical shapes of the Ni3-Cu-P electrode material provide more electroactive sites and a larger active surface area for faradaic reaction. In electrochemical energy storage applications, the Ni3-Cu-P electrode outperformed the bare Ni-P and Cu-P electrodes, with the highest areal capacity (0.77 C/cm2), the lowest charge transfer resistance (81.7 Ω), and the highest capacity retention (83.9%) at 2.0 mA/cm2. The study indicates that the Ni3-Cu-P electrode's exceptional electrochemical properties result from the interaction between nickel and copper in the binary metal phosphate framework, making it an excellent choice for battery-type electrodes used in electrochemical energy storage applications.
