“…The working electrode is the SnS 2 anode, coupled with the graphite counter electrode in the window of −3.6 to −1.0 V, and the result is shown in Figure b. Two pairs of redox peaks could be seen in the curves, and with the increase in scan cycles, the reduction peaks shift from −2.67 and −3.10 to −3.22 and −3.43 V, respectively, revealing the intercalation of Li ions and TFSI – cations during the charging process. − Two oxidation peaks appear at −3.02 and −2.27 V, and the curves overlap well, confirming the de-intercalation of Li ions and TFSI – cations. Besides, Figure S6 shows the CV curves of the different low cutoff voltages (−3.7 and −3.8 V).…”

Energy issues have attracted great concern worldwide. Developing new energy has been the main choice, and the exploitation of the electrochemical energy storage devices plays an important role. Herein, a high-performance dual-ion battery system is proposed, which consists of a graphite cathode and SnS 2 anode, with a high-concentration lithium salt electrolyte (4 M LiTFSI). The benefits from the typical sandwich-like layer structure of SnS 2 are as follows: the highest discharge specific capacity of the battery could reach 130.0 mA h g −1 at a current density of 100 mA g −1 , and even under an ultra-high current density of 2000 mA g −1 , the highest capacity of 66.3 mA h g −1 is still achieved, with an outstanding capacity retention over 100% after 1000 cycles. Inspiringly, this system delivers an excellent low self-discharge of 1.19%/h, surpassing most of the reported dual-ion batteries. In addition, the working mechanism and structural stability are also investigated by X-ray diffraction and Raman spectra, indicating a good reversibility. These results reveal that this graphite/SnS 2 dualion battery system could provide a promising alternative for a future high-performance energy storage device.

“…Birnessite-type sodium molybdate prepared by the simple addition of water molecules has been used as both the electrode (anode and cathode) material as a dual-ion material. The structural arrangement of atoms in this material creates adequate space for volume occupancy, restraining pulverization and increasing ion diffusion [366].…”

Metal-ion batteries are capable of delivering high energy density with a longer lifespan. However, they are subject to several issues limiting their utilization. One critical impediment is the budding and extension of solid protuberances on the anodic surface, which hinders the cell functionalities. These protuberances expand continuously during the cyclic processes, extending through the separator sheath and leading to electrical shorting. The progression of a protrusion relies on a number of in situ and ex situ factors that can be evaluated theoretically through modeling or via laboratory experimentation. However, it is essential to identify the dynamics and mechanism of protrusion outgrowth. This review article explores recent advances in alleviating metal dendrites in battery systems, specifically alkali metals. In detail, we address the challenges associated with battery breakdown, including the underlying mechanism of dendrite generation and swelling. We discuss the feasible solutions to mitigate the dendrites, as well as their pros and cons, highlighting future research directions. It is of great importance to analyze dendrite suppression within a pragmatic framework with synergy in order to discover a unique solution to ensure the viability of present (Li) and future-generation batteries (Na and K) for commercial use.

In order to meet the growing demand for the electronics market, many new materials have been studied to replace traditional electrode materials for energy storage systems. Molybdenum oxide materials are electrode materials with higher theoretical capacity than graphene, which was originally used as anode electrodes for lithium-ion batteries. In subsequent studies, they have a wider application in the field of energy storage, such as being used as cathodes or anodes for other ion batteries (sodium-ion batteries, potassium-ion batteries, etc.), and electrode materials for supercapacitors. However, molybdenum oxide materials have serious volume expansion concerns and irreversible capacity dropping during the cycles. To solve these problems, doping with different elements has become a suitable option, being an effective method that can change the crystal structure of the materials and improve the performances. Therefore, there are many research studies on metal element doping or non-metal doping molybdenum oxides. This paper summarizes the recent research on the application of hetero-element-doped molybdenum oxides in the field of energy storage, and it also provides some brief analysis and insights.
