Synergistic effect of nickel (II) phthalocyanine as a promising electrode material for high-performance lithium-ion batteries

초록

The increasing demand for efficient energy storage solutions has accelerated the development of novel electrode materials with enhanced capacity, cycling stability, and energy density. The electrochemical properties of charge/discharge behaviour having unique electronic structure, conductivity, and thermal and structurally stable materials are needed to resolve energy storage impediments. Here, we designed and fabricated the high-redox active and efficient charge transferring oxygen-bridged nickel (II) tetra-4-(quinolin-8-yloxy) phthalocyanine (NiPc) for lithium-ion batteries (LIBs). The designed NiPc was evaluated as an anode material in LIBs through cyclic voltammetry and galvanostatic charge-discharge tests. Further, the fabricated NiPc exhibited cycling performance of 255.5 mA g- 1 at 100 mA g-1, and the 10 wt% single walled carbon nanotube (SWCNT)-doped NiPc (NiPc/10 wt% SWCNT) composite demonstrated an exceptional cycling performance of 703.5 mA g- 1 at 100 mA g- 1. The enhanced performance of NiPc/SWCNT is not only attributed to facile lithium-ion diffusion, exceptional rate capacity, and long-term stability but also significantly contributed to the development of sustainable and high efficiency alternatives for energy storage applications.
