“…This electrolyte possesses different degrees of Lewis acidity depending on the [EMIm]Cl : AlCl 3 ratio, which provides an additional degree of freedom in tuning its properties. During discharge the prevalent AlCl 4 À anion in the electrolyte will react with the The V 2 O 5 cathode slurry was made by mixing 85% of the synthesized V 2 O 5 nano-wires, 7.5% super-p carbon and 7.5% of PVDF binder in NMP dispersant. Electrodes were produced by coating the slurry onto a 10 micron stainless steel current collector at 105 1C for 1 h initially and at 100 1C for 4 h in a vacuum oven.…”

We report a novel aluminium-ion rechargeable battery comprised of an electrolyte containing AlCl 3 in the ionic liquid, 1-ethyl-3-methylimidazolium chloride, and a V 2 O 5 nano-wire cathode against an aluminium metal anode. The battery delivered a discharge capacity of 305 mAh g À1 in the first cycle and 273 mAh g À1 after 20 cycles, with very stable electrochemical behaviour.Since the early 1990s, lithium ion batteries based on a carbonaceous material such as graphite as the anode, a lithiated metal oxide (LiMO, e.g. LiCoO 2 ) cathode, and an aprotic liquid electrolyte have been the subjects of intense scientific and commercial interest for portable electronics applications. In recent years, the demand for secondary/rechargeable batteries with higher operating voltages, improved cycling stability, higher power densities, enhanced safety, and lower initial and life cycle costs has increased to meet new needs for smaller, lighter, more powerful electronic devices. Growing interest in hybrid electric vehicles (HEV) and plug-in hybrid electric vehicles (PHEVs) designed to simultaneously reduce dependence on fossil fuel-derived energy and to lower the carbon footprint of humans compounds the current need for advanced, cost-effective electrical energy storage technologies. 1Due to their high energy density and low self-discharge rate, Li-ion batteries are considered the most promising technology for meeting these demands for the foreseeable future. 2-4Aluminium is the most abundant metal and the third most abundant element in the earth's crust. An aluminium-based redox couple, which involves three electron transfers during the electrochemical charge/discharge reactions, provides competitive storage capacity relative to the single-electron Li-ion battery.5-7 Additionally, because of its lower reactivity and easier handling, such an aluminium-ion (Al-ion) battery might offer significant cost savings and safety improvements over the Li-ion battery platform. Aluminium has consequently long attracted attention as an anode in the Al-air battery because of its high theoretical Ampere-hour capacity and overall specific energy. [8][9][10][11] Although these values are reduced in a practical battery because of the inability to operate aluminium and the air cathode at their thermodynamic potentials, and because water is consumed in the discharge reaction, the practical energy density still exceeds that of most commercially available rechargeable battery systems. 12 The inherent hydrogen generation of the aluminium anode in aqueous electrolytes introduces additional limitations, which have been met by designing the batteries as reserve systems with the electrolyte added just before use, or as mechanically rechargeable batteries with the aluminium anode replaced after each discharge. Even with these adjustments, reliable electrically rechargeable aluminium/air batteries are considered unfeasible using aqueous electrolytes, due to the high corrosion and hydrogen evolution of aluminium in the electrolyte, which leads to a sharp red...

“…The refinement results indicate that all diffraction peaks shift to the larger angles with the increasing pressure and weak peaks in the 2θ range of 8-9 • are retained. 24,25 As shown in Fig. 2(b), the pattern measured at 19.7 GPa is refined.…”

“…[39,40] Among them, Li and Mn-rich layered cathode materials, xLi 2 MnO 3 •(1-x)LiMO 2 (M = Mn, Ni, Co) show much higher specific capacity of ~ 250 mAh g -1 than that of conventional transition metal oxide cathodes. [41][42][43] Basically, Li 2 MnO 3 by itself cannot deliver high capacity, but a composite with LiMO 2 on a nanometric scale induces a reversible reaction of the excess Li. However, these Li and Mn-rich layered cathodes must still overcome drawbacks such as a large irreversible capacity at the first charging and a gradual decrease of the lithiation voltage during cycling.…”

Light metals have been widely used as electrode materials for batteries owing to their low standard redox potential, their low equivalent weight, large specific capacity, and great abundance. Both primary and secondary cells including light metals as electrode material have influenced all aspects of our lives, e.g., electrically operated toys, power tools, and portable electronics such as cell phones, smart pads, and laptop computers. Among all battery systems, rechargeable lithium (Li) ion cells have been used most widely in recent years owing to their high specific power, high energy density, and ambient temperature operation. However, Li‐ion cells are facing difficult challenges in satisfying the emerging market for advanced applications demanding high‐performance rechargeable batteries for applications such as electric vehicles, high‐performance portable electronics, and large‐scale electrical energy storage systems. Unfortunately, current Li‐ion cells cannot satisfy demands such as low cost, much improved safety, larger energy density, faster charge/discharge rates, and longer service life, so intensive effort is necessary to develop the next generation of cells. In this article, the limitations of current Li‐ion cells and various advanced materials for each component of the Li‐ion cell, in addition to other promising candidates for cells beyond Li ion, such as the Li/S cell and Na‐ and Mg‐based rechargeable cells, and metal/air cells are discussed.
