Summary: Among energy storage devices, lithium-ion capacitors (LICs) stand out due to their high energy densities and power densities. However, the mismatch in storage mechanisms between the positive and negative materials limits the performance of LICs. In this study, a Sn-based heterostructure@MXene anode material was synthesized to achieve excellent rate performance and increased lithium storage capacity, leading to a better match with the cathode. The hybrid electrode demonstrated remarkable rate performance and cycle stability, reducing the kinetic gap with capacitor-type cathodes. Assembled LICs based on this hybrid anode and nitrogen-doped activated carbon cathode exhibited high power/energy density and long cycling life.

Summary: Metal-organic frameworks (MOFs) are promising materials for supercapacitors due to their unique porous structure, high surface area, and active sites. In this study, a nickel-cobalt sulfide heterostructure (CoS1.097/Ni9S8/CC) was designed and fabricated on a carbon cloth using MOFs as templates. The CoS1.097/Ni9S8 heterostructure showed higher capacitance (596.4 C g(-1)) compared to CoS1.097/CC (92.6 C g(-1)) at 2 A g(-1). The high electrochemical performance of CoS1.097/Ni9S8 was attributed to its high hydrophilicity, abundant active sites, and good electrical conductivity. By using CoS(1.097)/Ni9S8/CC as the positive electrode and activated carbon as the negative electrode, an asymmetric supercapacitor achieved a high energy/power density of 37.2 W h kg(-1)/375.9 W kg(-1) with 99.3% retention after 10,000 cycles. Therefore, developing methods to enhance the conductivity of MOFs is of great significance for their application in supercapacitors.

Summary: In this study, multishelled hollow structures (HoMSs) with different shell numbers, thicknesses, pore sizes, surface areas, and void sizes were successfully synthesized using carbon microspheres as a hard template and two different strategies: two-step strategy (TsS) and one-step strategy (OsS). The ZnO@TiO2 HoMSSs synthesized by OsS (triple shelled) exhibited excellent potassium storage capacity, rate capability, reversibility, and cyclic life in aqueous alkaline batteries, thanks to the thinner shell, larger pore size, high surface area, and bigger voids that provided a distinctive buffering zone for charge-discharge and improved the structural stability and cycling stability during the OH- intercalation/de-intercalation process.

Summary: In this study, the geometric, electronic, and nonlinear optical properties of spiropyranes thermochromes were investigated using DFT methods. It was found that the open isomers of spiropyranes exhibited lower HOMO-LUMO energy gaps, lower excitation energy, and larger first hyperpolarizability values compared to the closed isomers. The frequency-dependent hyperpolarizability and refractive index analysis showed a significant increase in the nonlinear optical response with increasing frequency. The open isomer of spiropyran 1 exhibited the highest refractive index value. Molecular absorption analysis confirmed the electronic excitation in the open isomers. These reversible thermochromic compounds have excellent potential as nonlinear optical molecular switches for advanced electronics design.

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.
