Transition metal phosphate is the prospective electrode material for supercapacitors (SCs). It has an open frame construction with spacious cavities and wide aisles, resulting in excellent electric storage capacity. However, inferior rate behavior cycling stability of transition materials alkaline environments pose significant barriers to their application SCs. Herein, Ni11(HPO3)8(OH)6/Co3(HPO4)2(OH)2 heterostructured synthesized through a one-step hydrothermal process exhibiting remarkable capability coupled exceptional endurance. samples exhibit micron-scale structure composed sheet-like compositions unique pore structure. The multistage favorable promoting diffusion protons ions, enhancing sample’s electrochemical Upon conducting tests, it was observed that composite surpassed both standalone Ni11(HPO3)8(OH)6 Co3(HPO4)2(OH)2 electrode, achieving specific capacity 163 mAh g−1 efficiency at 1 A g−1. Notably, this also exhibits superior performance, maintaining 82.5% 71% its original full even 50 100 g−1, respectively. Furthermore, demonstrates cycling, retaining 92.7% 10 after 5000 cycles. Moreover, porous carbon (PC) were assembled into hybrid supercapacitor (HSC). Electrochemical tests reveal impressive power density up 36 kW kg−1 energy 47.4 Wh HSC. Ni11(HPO3)8(OH)6/Co3(HPO4)2(OH)2//PC HSC robust retention 92.9% enduring 10,000 cycles 3 demonstrating durability. This work imparts viewpoints design materials.
