EDHA for energy production, storage and conversion devices

Abstract

Electrohydrodynamic atomization (EHDA) or electrospraying stands out in thin film deposition because of its unique ability to form charged droplets, initiating higher deposition efficiencies in electrostatic spray deposition. Considering that the quality of a thin film depends on the particle sizes, their monodispersity and uniform distribution on the surface, electrospray is a powerful tool in materials synthesis. Therefore, this review looks at different areas where this novel technique has been used to improve on the overall performance of materials for energy devices, such as solar cells, photoelectrochemical cells, rechargeable batteries and beyond, capacitors, and (O)LEDs, including quantum dots.

Review on water electro-sprays and applications of charged drops with focus on the corona-assisted cone-jet mode for High Efficiency Air Filtration by wet electro-scrubbing of aerosols

“…Dense to hollow dried particles are achieved with subsequent tunable porosity of final powders. This is especially critical to produce membranes with defined apparent exchange surface and composition required in most industrial domains from energy production, conversion, and storage and more generally to catalysis or polymers membranes (Castillo et al, 2018;Kelder et al, 2018;Rosell-Llompardt et al, 2018a). The properties of the dried particles, including composition, size and morphology can be tuned by controlling the initial droplet size and the drying conditions with related droplet evaporation rates and subsequent production rates of nanoparticle suspended in the droplet on the one hand and on the other, the diffusion rate of so-formed nano-crystal.…”

“…ES deposition of living bacteria and bio-molecules and self-patterning of Carbon nanotube and graphene in watersuspension have been achieved. It is also used for the production of nano-composite materials doped with nano-oxides, polymer fibers loaded with Metal catalysts for fabrics, porous membranes for energy production with fuel-cells, conversion in solar cells and storage in capacitors, sensors for gas detection (De Juan et al, 1996;Chen CH et al, 1999;Jayasinghe et al, 2002;Jayasinghe et al, 2005a, b;Wang DZ et al, 2005;Jayasinghe, 2006;Wang DZ et al, 2007a;Yu et al, 2007;Kim K et al, 2008;Prajapati et al, 2010;Wang D et al, 2011;Wang D et al, 2013;Krella et al, 2017;Castillo et al, 2018;Kelder et al, 2018).…”

Electrostatically Sprayed Nanostructured Electrodes for Energy Conversion and Storage Devices

“…The objectives, discussions, and interpretations of Zhu et al., [ 8 ] Wang et al., [ 10 ] and Kelder et al. [ 9 ] differ from this review in several respects. The present review provides a survey of recent reports on E‐spray for a broad range of energy conversion and storage devices.…”

“…Although numerous reports of the utilization of E-spray in the energy field have been presented, very few reviews are available on either energy conversion or storage electrodes. [8][9][10] In one recent publication, Zhu et al [8] presented a highly focused review on Li and Na-ion-based battery electrodes fabricated using E-spray, covering various oxides and sulfides without going into the detailed comparison of electrochemical performance and discussing the impact of electrode morphology. The discussion of process parameters is excellent; however, it is confined to specific materials for energy storage applications only.…”

“…Kelder et al. [ 9 ] briefly cover E‐spray applications in photovoltaics (PVs) and photonic devices such as solar cells and organic light‐emitting diodes. They have reviewed a few of the reports on E‐spray deposition of LIB cathodes and highlighted electrode structures for Na‐ion and Li–S batteries.…”
