Abstract With the expanding adoption of large‐scale energy storage systems and electrical devices, batteries supercapacitors are encountering growing demands challenges related to their capability. Amorphous/crystalline heterostructured nanomaterials (AC‐HNMs) have emerged as promising electrode materials address these needs. AC‐HNMs leverage synergistic interactions between amorphous crystalline phases, along with abundant interface effects, which enhance capacity output accelerate mass charge transfer dynamics in electrochemical (EES) devices. Motivated by elements, this review provides a comprehensive overview synthesis strategies advanced EES applications explored current research on AC‐HNMs. It begins summary various Diverse devices AC‐HNMs, such metal‐ion batteries, metal–air lithium–sulfur supercapacitors, thoroughly elucidated, particular focus underlying structure–activity relationship among amorphous/crystalline heterostructure, performance, mechanism. Finally, perspectives for proposed offer insights that may guide continued development optimization.

Morphological control of metal-organic frameworks (MOFs) at the micro/nanoscopic scale is critical for optimizing electrochemical properties them and their derivatives. In this study, manganese organic phosphate (Mn-MOP) with three distinct two-dimensional (2D) morphologies was synthesized by varying molar ratio Mn2+ to phenyl phosphonic acid, one a unique palm leaf shape. addition, series 2D Mn-MOP derivatives were obtained calcination in air different temperatures. Electrochemical studies showed that derivative calcined 550 °C exhibited superior specific capacitance 230.9 F g−1 0.5 A 3 M KOH electrolyte. The aqueous asymmetric supercapacitor constructed flexible solid-state device demonstrated excellent rate performance. This performance reveals promising application materials energy storage.

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.
