Abstract Large area highly crystalline MoS 2 and WS thin films were successfully grown on different substrates using radio-frequency magnetron sputtering technique. Structural, morphological thermoelectric transport properties of 2, have been investigated systematically to fabricate high-efficient thermal energy harvesting devices. X-ray diffraction data revealed that crystallites are oriented in 002 plane with uniform grain size distribution confirmed through atomic force microscopy study....
All-solid-state batteries (ASSBs) are gaining traction in the arena of energy storage due to their promising results producing high density and long cycle life coupled with capability being safe. The key challenges facing ASSBs low conductivity slow charge transfer kinetics at interface between electrode solid electrolyte. Garnet solid-state electrolyte has shown improving ion but still suffers from poor capacity retention rate performance interfacial resistance electrodes. To improve...
With their relative ease of production and coupled strong surface functionality electrical conductivity properties, graphene oxide (GO) reduced (rGO) are exciting, yet overlooked, graphene-like additive prospects for activated carbon (AC) electrodes in supercapacitors. In this work, we incorporated small amounts synthesized GO rGO AC via a simple mixing procedure to explore effects. addition materials characterizations, symmetric supercapacitors were made from these tested across current...
Abstract The drawbacks of common anodes in lithium-ion batteries (LIBs) and hybrid supercapacitors (HSCs), such as the high voltage plateau Li 4 Ti 5 O 12 (1.55 V vs. Li/Li + ) moderate capacity graphite (372 mAh-g -1 ), have established a need for better materials. Conversion materials, particular iron oxide CaFe 2 (CFO), amassed recent attention potential anode replacements. In this study, we evaluate material electrochemical effects solution combustion synthesis (SCS) porous CFO across...
Li2FeMn3O8 (LFMO) nanocomposite material for Li-ion battery is synthesized using chemical combustion method. To fabricate a hybrid nanostructure electrode, LFMO coated on tin oxide (SnO2) nanorods (NR), which grown vapor-liquid solid (VLS) technique steel substrate. The surface morphology of the electrode confirms that, single crystalline SnO2 are vertically with spine-like structures, few microns in length, as evident from field emission scanning electron microscope image. electrochemical...
