A “self-deconstruction-self-weaving” mechanism is believed to be responsible for the formation of such nanotube-assembled crumpled sheet-like architectures from the nickel glycerate template. The asymmetric supercapacitor (ASC) device assembled using nanotube-assembled amorphous 2D nickel phosphate (NiHPi-500) as the positive electrode and activated carbon (AC) as the negative electrode exhibits high energy densities of 50 W h kg-1, 40 W h kg-1, and 32 W h kg-1 at power densities of 362 W kg-1, 1443 W kg-1, and 2838 W kg-1, respectively. Furthermore, this ASC device can retain an impressive energy density of 18 W h kg-1 at high power density of 7242 W kg-1. In addition, the NiHPi-500//AC ASC also displays good long-term stability with a high capacitance retention of 100% after 5000 cycles at a high current density of 10 A g-1. The excellent electrochemical performance is attributed to the unique nanotube-assembled 2D architectures, the good interconnectivity between the nanotubes, and the large surface area arising from such structures which can provide many active sites for the redox reactions and facility effective transport and diffusion of the electrolyte ions, leading to more efficient utilization of the active material. These results indicate the promising potential of nanotube-assembled 2D nickel phosphate nanoarchitectures for supercapacitor applications.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Asymmetric supercapacitor,Capacitance retention,Electrochemical performance,High current densities,Metal phosphates,Supercapacitor application,Template based methods,Transport and diffusions[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Metal phosphate,Nanotubes,Self-assembly,Supercapacitors,Template-based method,Two-dimensional[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][{‘$’: “This work was supported by Australian Research Council (ARC) Future Fellowship (FT150100479) and World Class Professor (WCP) program (Grant No. 123.11/D2.3/KP/2018).
