The low intrinsic conductivity of carbon monofluoride (CFx) extremely limits the high-power application of lithium/carbon monofluoride (Li/CFx) primary batteries. Herein, silver nanowires were grown in situ on the surface of CFx material by an aldehyde reduction method in polyhydric alcohol. The interface interaction between silver nanowires (Ag NWs) and the surface of CFx material was studied. Ag NWs@CFx hybrids modulate the electronic structure of CFx and enhance the electrochemical activity of C–F bonds, thus increasing the availability of F atoms to participate in the discharge reaction. The electrochemical performance results show that the voltage platform, specific capacity, and energy density of the Li/CFx batteries were enhanced with a certain concentration of Ag NWs on the CFx surface. The 10% Ag NWs@CFx sample achieved a power density of 10376.09 W/kg and an energy density of 840 Wh/Kg at a discharge rate of 8C, which is significantly better than the pristine CFx. The perfo
In this study, new composite materials comprising zeolitic imidazolate framework (ZIF) structures and microchannel glass (MCG) plates were fabricated using the hydrothermal method and their morphological and spectral properties were investigated using XRD, SEM, FTIR, and Raman spectroscopy. XRD studies of powder samples revealed the presence of an additional phase for a ZIF-8 sample, whereas ZIF-67 samples, which were prepared through two different chemical routes, showed no additional phases. A detailed analysis of the FTIR and micro-Raman spectra of the composite samples revealed the formation of stable ZIF structures inside the macropores of the MCG substrate. The hydrophilic nature of the MCG substrate and its interaction with the ZIF structure resulted in the formation of stable ZIF-MCG composites. We believe that these composite materials may find a wide range of important applications in the field of sensors, molecular sieving.
It is challenging to hydrothermally synthesize solution-processable MoS2, as the strong van der Waals force between MoS2 nanosheets induces self-assembly of agglomerates. Here, we introduce poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) into the precursor to impede aggregate formation in the hydrothermal process. A hybrid MoS2/PEDOT:PSS (MP) hydrogel is formed due to the electrostatic interactions between the negatively charged MoS2 and positively charged PEDOT chains. This hydrogel can be easily dispersed in water for subsequent solution processing such as vacuum filtration to form free-standing flexible films or extrusion 3D printing to create novel patterns. The MP film with a fracture strength of 18.59 MPa displays excellent electrochemical performance in both aqueous Na2SO4 electrolyte (474 mF cm-2) and solid-state PVA-H3PO4 electrolyte (360 mF cm-2). Flexibility and robustness can be evidenced by high capacitance retention rates of 94 and 89% after being repe
