“…While the energy density is modest (the discharge voltage is <1 V), this significance here is that the electronic structure of various hosts has been ignored relative to the crystal structure, but may be invoked to explain the good performance of materials with strongly hybridized metal-anion molecular orbitals. Such materials include TiS 2 [121], WSe 2 [173], and MoS 2 [161] in the case of MIBs, and CoO 2 [16] and MnO 2 [174] in the case of LIBs.…”

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...

“…3b exhibited the images of the tightly knotted MoS 2 /MWCNT and rGO/MWCNT fibers, indicating the great flexibility of the composites [21]. In another study, Liu et al [46] synthesized a 2D tin selenide nanostructure with a simple solvent method. The as-exhibited high electrochemical performance and specific capacitance of these materials indicated a great potential in future electronic devices, including SCs.…”

“…In addition to the flexible LIBs and SIBs for energy storage, there are rapid developments for flexible magnesium ion batteries [46], potassium ion batteries [47], lithium-O 2 batteries [48] and lithium sulfur batteries [49] for energy storage. With the development of science and technology, it will not be long before NB2DMs materials are applied to these batteries for flexible energy storage.…”

Newborntwo-dimensional materials (NB2DMs) beyond graphene such as transition metal dichalcogenides (TMDs) exhibit excellent optoelectronic and mechanical properties as well as high theoretical specific capacity, which make them become the promising building blocks of flexible energy devices related to energy conversion and storage. Compared to graphene with zero band gap or traditional friable materials such as Si, these NB2DMs are more suitable to construct flexible devices as active layers of optoelectronic devices or as active materials for batteries. The present review focuses on the recent advances in bendable energy devices based on NB2DMs, including batteries, supercapacitors (SCs), solar cells, photodetectors and nanogenerators (NGs). The NB2DMs pave a new way to construct next-generation flexible energy devices with improved performance and we believe that those devices will be seen in our daily life and change our lifestyle in the immediate future.

This review describes recent advances in electrochemical water electrolysis and rechargeable beyond Li-ion battery research, two emergent and widely employed technologies playing important roles in clean energy production and storage. The principle components of these electrochemical processes are electrode materials, which are currently facing challenges in performance improvement, thus motivating the development of novel electrode materials. This development requires synergistic interactions between experimentalists and theorists with backgrounds in solid state chemistry, condensed matter physics, and materials science and engineering. In light of a large amount of literature covering the topic, we will focus this review on the seminal electrode materials that have been discovered in the last five years, such as transition metal chalcogenides, carbides, and phosphides, as well as 2D layered materials. Intensive cross-disciplinary research is also dedicated to nanostructuring and hybridization of the emerging electrode materials in order to maximize the efficiency and simultaneously to lower the cost of the processes. As the understanding of the nanoscale-related effects deepens, it opens important pathways to the discovery of further materials and their improvement.
