Summary: In this study, an electrospun gel polymer electrolyte (GPE) membrane, integrated with its Cu foil collector (Cu@GPE), was prepared. The Cu@GPE acts as both electrolyte and artificial solid-electrolyte interphase (ASEI), and the strong electrostatic interaction between the fiber sheet and the Cu foil collector positively affects the fluidity of deposited Li. The Cu@GPE|Li cell showed outstanding performance even at high current density, and when coupled with LiNi0.33Mn0.33Co0.33O2 (NMC), the Cu@GPE|NMC AFLMB exhibited superior performance compared to Cu|cGPE|NMC.

Summary: Nowadays, triboelectric nanogenerators (TENGs) are gaining popularity due to their simple and cost-effective structure, which allows them to harvest mechanical energy from the environment. In this study, dielectric zinc tin oxide (ZnSnO3) nanoparticles were synthesized and combined with a polyvinylidene fluoride hexafluoropropylene (PVDF-HFP) polymer to create ZnSnO3/PVDF-HFP nanofibrous films for the fabrication of a TENG. The performance of the TENG was optimized by varying the loading concentration of ZnSnO3 nanoparticles. The highest voltage, current, charge density, and power density achieved by the TENG were 138 V, 5 mu A, 52 mu C/m(2), and 1.6 W/m(2), respectively. The long-term mechanical stability and practical application of the TENG were also investigated.
