Nickel-cobalt (NiCo) phosphides (NCPs) possess high electrochemical activity, which makes them promising candidates for electrode materials in aqueous energy storage devices, such as supercapacitors and zinc (Zn) batteries. However, the actual specific capacitance rate capability of NCPs require further improvement, can be achieved through reasonable heterostructural design loading conditions active on substrates. Herein, novel hierarchical Bi-NCP heterogeneous structures with built-in electric fields consisting bismuth (Bi) interlayers (electrodeposited carbon cloth (CC)) are designed fabricated to ensure formation uniform high-load layered efficient charge ion transport. The resulting CC/Bi-NCP electrodes show a uniform, continuous, mass (>3.5 mg) superior reaching 1200 F g
