Abstract
Recently, stretchable micro-supercapacitors (MSCs) that can be easily integrated into electronic devices have attracted research and industrial attentions. In this work, three-dimensional (3D) stretchable MSCs with an octet-truss electrode (OTE) design have been demonstrated by a rapid digital light processing (DLP) process. The 3D-printed electrode structure is beneficial for electrode-electrolyte interface formation and consequently increases the number of ions adsorbed on the electrode surface. The designed MSCs can achieve a high capacitance as ≈74.76 mF cm-3 under 1 mA cm-3 at room temperature even under a high mechanical deformation, and can achieve 19.53 mF cm-3 under 0.1 mA cm-3 at a low temperature (-30 °C). Moreover, finite element analysis (FEA) reveals the OTE structure provides 8 times more contact area per unit volume at the electrode-electrolyte interface compared to the traditional interdigital electrode (IDE). This work combines structural design and 3D printing techniques, which provides new insights into highly stretchable MSCs for next-generation electronic devices.

Abstract
Graphene-based nanomaterials have sprung up as promising anode materials for sodium-ion batteries due to the intriguing properties of graphene itself and the synergic effect between graphene and active materials. However, the 2D graphene sheet only allows the rapid diffusion of sodium ions along the parallel direction while that of the vertical direction is difficult, limiting the rate capability of graphene-based electrode materials. To tackle this problem, pore-forming engineering has been employed to perforate graphene and concurrently achieve the in situ growth of Co3 Se4 nanoparticles. The generation of in-plane nanohole breaks through the physical barriers of the graphene nanosheets, enabling the fast diffusion of electrolyte ions in the longitudinal direction. In addition, this design limits the aggregation of Co3 Se4 nanoparticles because of the high affinity of Co3 Se4 on graphene. Benefiting from the high conductivity and fast ion transport bestowed by the ingenious architecture, the Co3 Se4 /holey graphene exhibits a remarkable rate performance of 519.5 mAh g-1 at 5.0 A g-1 and desirable cycle stability. Conclusions drawn from this investigation are that the transport of sodium inside the graphene-based composites is crucial for rate performance enhancement and this method is effective in modifying graphene-based nanomaterials as potential anode materials.

Abstract
Micro/nanomaterials with multilayer core-shell structures are receiving widespread attention due to their potential in energy storage and conversion systems. However, simple fabrication of multilayered core-shell structured micro/nanomaterials with a consistent composition still faces a great challenge. Herein, a simple one-step solvothermal method is used to fabricate Cu-based metal organic framework multilayer core-shell microspheres (Cu-MOF-MCSMSs) as efficient oxygen reduction reaction (ORR) catalysts. The systematic structural evolution of Cu-MOF-MCSMSs is from microspheres to core-shell microspheres and then to multilayer core-shell microspheres. Additionally, different transition metal cations and anions can also influence the structures, compositions and thus ORR activities of the synthesized MOFs. The representative Cu-MOF-MCSMSs exhibit high ORR activity and cycling stability. The simple method can provide a good guide to fabricate other micro/nanomaterials with multilayer core-shell structures and desirable properties.
