With the rapid advancement of energy storage and conversion systems (ESCSs), renewable energy can achieve a smooth and continuous output capacity. Nevertheless, commercial precious metal-based multifunctional ESCSs materials are plagued by issues like scarcity and high production costs. This study adopted microemulsion and chemical vapor deposition (CVD) strategies to fabricate single crystal Ni 5 P 4 nanoparticles successfully. Due to its excellent crystal integrity and high electrical conductivity, single crystal Ni 5 P 4 offers abundant active sites for redox reactions. Additionally, it allows electrons and ions to move more efficiently and freely, making it a highly promising multifunctional material for ESCSs. For supercapacitors (SCs), the prepared Ni 5 P 4 -10 electrode possesses a battery-like behavior with a high specific capacity of 1643.13 F g –1 @0.5 A g –1 . The corresponding assembled Ni 5 P 4 -10//AC hybrid SCs (HSCs) exhibit a maximum energy density of 37.78 Wh kg –1 at a power density of 400 W kg –1 . Furthermore, Ni 5 P 4 -10 displays low overpotentials of 150 mV@HER and 250 mV@OER at 10 mA cm –2 when it serves as an electrocatalyst. This study offers a novel perspective for the design of MOF-derived multifunctional ESCSs materials.
