We report the synthesis of cobalt sulfide multishelled nanoboxes through metal-organic framework (MOF)based complex anion conversion and exchange processes.The polyvanadate ions react with cobalt-based zeolitic imidazolate framework-67 (ZIF-67) nanocubes to form ZIF-67/cobalt polyvanadate yolk-shelled particles.T he as-formed yolkshelled particles are gradually converted into cobalt divanadate multi-shelled nanoboxes by solvothermal treatment. The number of shells can be easily controlled from 2t o5by varying the temperature.F inally,c obalt sulfide multi-shelled nanoboxes are produced through ion-exchange with S 2À ions and subsequent annealing. The as-obtained cobalt sulfide multi-shelled nanoboxes exhibit enhanced sodium-storage properties when evaluated as anodes for sodium-ion batteries. Fore xample,ahigh specific capacity of 438 mAh g À1 can be retained after 100 cycles at the current density of 500 mA g À1 .The fast depletion of fossil fuels and growing environmental concerns have prompted intense research efforts for the development of clean and sustainable energy storage and conversion technologies.Electrical energy storage devices as one of the most important components in the development of sustainable energy systems have attracted significant research interest. [1][2][3] Besides lithium-ion batteries (LIBs), sodium-ion batteries (SIBs) have been considered as one promising energy storage alternative because sodium is abundantly available. [2,[4][5][6][7][8] Among the potential negative electrode materials for SIBs,t ransition metal sulfides (TMSs) are quite attractive because of their rich redox sites,high capacity and enhanced electrical conductivity compared with their oxide counterparts. [9][10][11][12][13] However,p ractical applications of TMSs are still hindered by the poor rate performance and fast capacity fading due to the low intrinsic electric conductivity, gradually reduced crystallinity and inevitable volume changes during prolonged cycling.To circumvent these problems,r ational design of the structural complexity of active materials has been proved ap romising strategy. [9,[14][15][16][17][18] In particular,h ollow structures with complex interiors have drawn significant attention owing to their structure-dependent merits.A sf or sodium storage applications,i ntricate hollow structures exhibit great advantages over simple hollow architectures. [16,[19][20][21] Complex hollow particles not only inherit all the advantages of hollow structures,i ncluding high surface area, enhanced volume change accommodation and large electrode/electrolyte interface,b ut also improve the weight fraction of active species,thus dramatically enhancing the energy density of the electrode materials. [22] As ar esult, av ariety of electrode materials have been fabricated in the form of multi-shelled hollow structures. [23][24][25][26][27][28][29][30][31] It is also noted that non-spherical particles might exhibit some advantage for SIBs, [9,15] owing to their larger surface area compared to spherical counterpart...

This work presents a pathway for Saudi Arabia to transition from the 2015 power structure to a 100% renewable energy-based system by 2050 and investigates the benefits of integrating the power sector with the growing desalination sector. Saudi Arabia can achieve 100% renewable energy power system by 2040 while meeting increasing water demand through seawater reverse osmosis (SWRO) and multiple effect distillation (MED) desalination plants. The dominating renewable energy sources are PV single-axis tracking and wind power plants with 243 GW and 83 GW, respectively. The levelised cost of electricity (LCOE) of the 2040 system is 49 €/MWh and decreases to 41 €/MWh by 2050. Corresponding levelised cost of water (LCOW) is found to be 0.8 €/m 3 and 0.6 €/m 3 . PV single-axis tracking dominates the power sector. By 2050 solar PV accounts for 79% of total electricity generation. Battery storage accounts for 41% of total electricity demand. In the integrated scenario, due to flexibility provided by SWRO plants, there is a reduced demand for battery storage and power-to-gas (PtG) plants as well as a reduction in curtailment. Thus, the annual levelised costs of the integrated scenario is found to be 1-3% less than the non-integrated scenario.

“…Research and development efforts developing battery-based high-energy storage technologies-chiefly grid-support systems and automotive, as well as aerospace electrical propulsion-are impeded by poorly understood, and consequently inefficiently controllable electrochemical phase-formation processes involved both in the fabrication and operation of the devices (Larcher and Tarascon 2014;Kittner et al 2017). In particular, lack of control over morphology and chemical-state distribution during electrodeposition is the key factor giving rise to damaging of electrodes, electrolytes and separators, ultimately resulting in capacity fade and mechanical failures (Finegan et al 2015;Yang et al 2017;Jin et al 2017).…”

Monitoring dynamic electrochemical processes with in situ ptychography

et al. 2018

View full text Add to dashboard Cite

The present work reports novel soft X-ray Fresnel CDI ptychography results, demonstrating the potential of this method for dynamic in situ studies. Specifically, in situ ptychography experiments explored the electrochemical fabrication of Codoped Mn-oxide/polypyrrole nanocomposites for sustainable and cost-effective fuel-cell air-electrodes. Oxygen-reduction catalysts based on Mn-oxides exhibit relatively high activity, but poor durability: doping with Co has been shown to improve both reduction rate and stability. In this study, we examine the chemical state distribution of the catalytically crucial Co dopant to elucidate details of the Co dopant incorporation into the Mn/polymer matrix. The measurements were performed using a custom-made three-electrode thin-layer microcell, developed at the TwinMic beamline of Elettra Synchrotron during a series of experiments that were continued at the SXRI beamline of the Australian Synchrotron. Our time-resolved ptychography-based investigation was carried out in situ after two representative growth steps, controlled by electrochemical bias. In addition to the observation of morphological changes, we retrieved the spectroscopic information, provided by multiple ptychographic energy scans across Co L 3 -edge, shedding light on the doping mechanism and demonstrating a general approach for the molecular-level investigation complex multimaterial electrodeposition processes.
