Enhancing the performance of electrode materials is an effective strategy for increasing energy density, power and lifespan supercapacitors. In this study, a one-step hydrothermal method employed to fabricate large-sized interlaced lamellar structure with Ni3(NO3)2(OH)4@MnO2 (NNM-2) heterojunctions loaded onto nickel foam. Then, uniform layer α-MnO2 nanosheets deposited create hierarchical Ni3(NO3)2(OH)4@MnO2/α-MnO2 (NNMM-2) via subsequent process. The interaction between various components, along increased number active sites, significantly improves electrochemical material. Furthermore, designed core–shell helps alleviate volume changes during charge discharge cycles, thereby improving stability Consequently, NNMM-2 demonstrates impressive specific capacitance 1261.3 F g–1 when measured at current density 1 A g–1. When as positive in asymmetric supercapacitor that features activated carbon negative electrode, it 36.5 W h kg–1 471.7 kg–1. After 7000 charge–discharge capacity retention rate remains 73% Coulombic efficiency 99%, demonstrating excellent capability. This research offers important perspectives on creation enhanced storage devices superior performance.
