Summary: Designing and constructing an ideal architecture is crucial for achieving high-performance energy storage systems. Core-shell heterostructure materials have been widely researched due to their excellent performance in energy storage applications. However, there have been few reports on core-shell heterostructures containing sandwich-like nano-array materials. In this study, sandwich-like NiCo-PPy-layered double hydroxide (NiCo-PPy-LDH) nanosheets with polypyrrole (PPy) as the intercalation agent were vertically anchored on a 3D cross-linked graphene nanoscroll (GNS) skeleton. The resulting NiCo-PPy-LDH@GNS composite exhibited impressive electrochemical properties, with a specific capacitance of 2561 F center dot g-1 and 82% capacitance retention at 10 A center dot g-1. The superior performance of the composite can be attributed to the novel heterostructure, which enhances the synergistic effect between NiCo-LDHs, GNSs, and PPy.

Summary: The rational design of highly oriented and integrated heterostructures based on metal-organic framework (MOF)-derived carbon containing n-type metal chalcogenides (Zn-In-S/C) polyhedron and p-type metal oxide (CuO) nanowires was proposed. The p-type CuO nanowires were used as a stable scaffold to grow MOF-derived n-type Zn-In-S/C. The controlled and in situ fabricated Zn-In-S/C@CuO heterostructures provided a p-n heterojunction which enhanced the charge transfer, hence providing an improved overall electrochemical performance over its MOF and bare CuO counterpart. Coupled with density functional theory (DFT) calculations, the enhancement in the conductivity of the heterostructure was further verified. The symmetric supercapacitor device delivered an energy density of 7 Wh kg-1 at a power density of 4 kW kg-1. Overall, the theoretical and experimental investigation of the oriented in situ grown Zn-In-S/C@CuO heterojunction with better cycling stability and electrochemical activity could be a useful asset for energy storage devices.

Summary: Symmetric pseudocapacitors (SPCs) have high power density and long life-span, but their energy density is insufficient for critical applications. In this study, we developed a low-cost silicon (Si) embedded in metal-organic framework (MOF)-derived cobalt nano-sized particles/nitrogen-doped carbon (Si/Co-NC) electrode material that works at positive and negative potential windows simultaneously. The optimized electrode with 30% Si content achieved remarkable capacitance and retained 97% of capacitance after 10,000 cycles. Additionally, a symmetric pseudocapacitor, Si/Co-NC1||Si/Co-NC1-SPC, showed a broader operating potential window range, excellent capacitance, and achieved the highest energy density reported for symmetric supercapacitors to date.
