“…Rapid capacity deterioration during the first eight cycles was attributed to passivation of the AZ31 Mg alloy (3% Al, 1% Zn, 96% Mg by weight) anode. Similar results were obtained when glucose was replaced with reduced graphene oxide as the carbon source [164]. The carbon served both to enhance conductivity and exfoliate the MoS 2 layers, allowing more access to insertion sites.…”

to develop and install renewable energy harvesting technologies [3]. However, their successful implementation will be dependent on reliable and robust storage devices since harvesting solar and wind energy is inherently intermittent and the majority of consumption targets cannot be readily tethered to the grid.As energy storage devices, batteries possess high portability, high energy density, high Coulombic efficiency, and long cycle life. They are ideal power sources for portable devices, automobiles, and backup power supplies; accordingly, batteries power nearly all of our mobile electronics and are used to improve the efficiency of hybrid electric vehicles [4,5]. Unfortunately, considerable improvements in performance are still required in order to meet the demands of advanced portable devices and achieve energy sustainability (e.g., through smart grid and electric vehicle technologies) [6]. These enduring needs have driven intensive research investments. While efforts have been successful, there is still significant room for improvement regarding the development and understanding of electrode materials [7]. The overall capacity and potential cycling window of many electrode materials are limited to prevent degradation over long term cycling. In addition to exploring new electrode materials, there have been strong efforts to improve those that are already utilized. Expense reduction is a priority as approximately 23% and 8% of the overall battery pack costs stem from the respective cathode and anode active materials alone [8].An alkali-ion battery consists of several electrochemical cells connected in parallel and/or in series to provide a designated current or voltage. Each electrochemical cell has two electrodes separated by an electrolyte that is electrically insulating but ionically conductive. During discharge, when the alkali-ion battery operates as a galvanic cell, alkali ions exit the negative electrode (typically carbon) and insert themselves into the positive electrode while electronsThe need for economical and sustainable energy storage drives battery research today. While Li-ion batteries are the most mature technology, scalable electrochemical energy storage applications benefit from reductions in cost and improved safety. Sodium-and magnesium-ion batteries are two technologies that may prove to be viable alternatives. Both metals are cheaper and more abundant than Li, and have better safety characteristics, while divalent magnesium has the added bonus of passing twice as much charge per atom. On the other hand, both are still emerging fields of research with challenges to overcome. For example, electrodes incorporating Na + are often pulverized under the repeated strain of shuttling the relatively large ion, while insertion and transport of Mg 2+ is often kinetically slow, which stems from larger electrostatic forces. This review provides an overview of cathode and anode materials for sodium-ion batteries, and a comprehensive summary of research on cathodes for magnesium-ion batteries. In additi...

“…31,32 Furthermore, in the XRD patterns of the nanohybrids it is difficult to distinguish diffraction peak at 2θ = 26º responsible for the (002) plane of graphitic carbon, which could be due to the disordered nature of the highly random stacking of the graphene nanosheets during the carbonation and annealing 33,34 as well as the reduced structure factor for this particular Bragg The composition and the degree of graphitization of the Co 3 O 4 @GNC nanohybrids have been evaluated by Raman spectroscopy (Fig.S6a). In the Raman spectra, two broad characteristic peaks, so called D band and the graphitic G band, located respectively at 1332…”

“…The value of Re, around 5 Ω, is much lower than those of the general MIB, [60][61][62][63] which is a benefit from the sponge-like morphology features of the U-Mn3O4 nanoparticles. The same tendency in Re also appeared in LFS of the Nyquist plots of U-Mn3O4.…”

Here, we are the first to report a spinel type Mn3O4 as cathode material for Mg-ion battery (MIB) with graphite foil (Gif) as current collector. High coulombic efficiency and good cyclic stability of Mn3O4 are demonstrated, and the process is enhanced by using Mn3O4 nanoparticles with a sponge-like morphology. The powder exhibits a network of interconnected mesopores with well-dispersed nanoparticles (~10 nm) and large specific surface area (102 m 2 g -1 ). This structural configuration provides easy access for electrolyte penetration which markedly enhances the utilization of electroactive material, generates high ion flux across the electrode-electrolyte interface and provides more active sites for electrochemical reactions to occur. This study can possibly open the way for exploring other similar compounds with a spinel type structure for MIB.
