Batteries are commonly considered one of the key technologies to reduce carbon dioxide emissions caused by transport, power, and industry sectors. We need remember that not only production energy needs be realized sustainably, but also for storage follow green guidelines emission greenhouse gases effectively. To reach sustainability goals, we have make batteries with performances beyond their present capabilities concerning lifetime, reliability, safety. commercially viable, technologies,...
The present study reports a straightforward template-free route for the synthesis of core–shell Co@CoO nanocomposites by controlled reduction Co3O4 nanospheres. target nanoparticles consist an unsealed hollow porous CoO shell with metal Co core, in which outer as active anode material can be fully contact electrolyte. void within particles provides remarkable buffer to tolerate volume changes electrode materials during insertion and extraction lithium. Most importantly, inner nanosized core...
A plum pudding-like Fe(3)O(4)/Fe/carbon composite was synthesized by a sol-gel polymerization followed heat-treatment process and characterized X-ray diffraction, Raman spectroscopic analysis, thermogravimetric scanning electron microscopy with energy-dispersive spectroscopy, transmission microscopy, electrochemical test. In this composite, uniform spherical Fe(3)O(4)/Fe nanoparticles of about 100 nm were embedded into carbon matrix high monodispersion. As-prepared electrode exhibits stable...
The conventional polyvinylidene fluoride (PVDF) binder works well with the graphite anode, but when combined silicon in composites to increase energy density of Li-ion batteries, it results severe capacity fade. Herein, by using scanning electron microscopy and energy-dispersive X-ray spectroscopy analyses, we reveal that this failure stems from loss connectivity between (or its agglomerates), graphite, PVDF because mechanical stresses experienced during battery cycling. More importantly,...
Silicon/graphite composites have the potential to improve practical energy density of Li-ion batteries enable mass-market penetration electric vehicles. However, they require polymeric binders that are compatible with both silicon and graphite can sustain alloying intercalation reactions as well associated interfacial reactions. In this work, chitosan, a natural cellulose, is crosslinked either molecular (citric acid) or (poly (acrylic acid), PAA) carboxylic acids form networks maximum...
A single-atom catalyst is a landmark finding in the catalysis field and due to its excellent catalytic efficiency maximum atom utilization, it widely applied hydrogen evolution reaction (HER), oxygen reduction (ORR), (OER). Herein, 3d, 4d, 5d single transition metal supported C4N catalysts (TM-C4N) are explored using density functional theory methods. First, seven thermodynamically stable TM-C4N (TM = Sc, Ti, V, Mn, Cu, Y, Ag) identified. Next, calculated ΔG*H values reveal that all screened...
The effects of the adjustment N coordination number in Sn single-atom catalysts toward activity and selectivity CO2 hydrogenation to HCOOH are systematically explored via density functional theory calculations. stability studied was evaluated by formation energy calculations, calculated results indicated that Sn-NxC4–x-G (x = 1–4) structurally stable. Through discussion reaction mechanism, optimal path on all is CO2* + H2* → HCOO* H* HCOOH*. In addition, they have different speed limit...
Silicon (Si) is recognized as a superior anode material in lithium-ion batteries (LIBs) compared with graphite, which currently used. Despite the high theoretical capacity (3579 mAh g−1) of Si, designing Si-based materials challenging because its large volume change (280 %) during charging and discharging processes. Mesoporous structured silicon (PSi) promising solution for overcoming expansion issue anodes. This study proposes feasibility using Si wafer waste to produce porous anodes LIBs....
