“…However, despite the well cited paper by Jayaprakash and co-workers [16] their results are controversial. As stated in, [63] the electrochemical activity of a V 2 O 5 cathode in an Al battery is the outcome of the stainless steel that was used as a current collector in the cathode. The electrochemical performance of V 2 O 5 is therefore the result of iron and chromium reactions in the stainless steel.…”

energy, [4] large scale and portable energy storage becomes increasingly more important. Therefore, continued research into high-performing alternatives, which will meet the increased demand is imperative. A common way of evaluating potential alternatives for Li-based batteries involves calculating the theoretical specific capacity of potential candidates and comparing these results with other figures of merit. This reasoning leads to the conclusion that metals in the upper left corner of the periodic table are more interesting than the others. Table 1 shows these calculations together with some other parameters for common metal anodes.A second important parameter when searching for potential battery materials is the oxidation potential of the anode, where lower (less noble) is better. Comparing these parameters for the metals listed in Table 1 shows immediately that Li is one of the most promising candidates, but rare. The second most promising metal is aluminium (Al), which has a relatively high standard oxidation potential. Heavier metals and those in higher groups show much worse performance indicators. Nevertheless, this method of evaluation has to be considered with caution, because it is based on numerous assumptions. Such as, that the anode is oxidized during the charging/discharging process, which is not true for many practical systems.The literature on non-Li based intercalation batteries is clearly dominated by sodium (Na), [9,10] magnesium (Mg) [11,12] and Al [13] systems that are all more abundant natural elements than Li. There are few examples of potassium (K) [14] and (Ca), [15] which coincides clearly with the trend observed in Table 1 (as mentioned above, low performing "candidates" have been omitted in this table). Great efforts are aimed at these alternatives to improve capacity, power and cycles. Comparing Na-ion with Li-ion batteries, the common feature is a monovalent ion that can be inserted/extracted into/from the electrode material. Here, only one charge transfer takes place in contrast to Mg-ion, Ca-ion or Al-ion where two and three charges are involved in redox reactions respectively. As a result of multielectron reactions, higher specific capacity and energy density may be obtained. A key issue in order for multivalent ion insertion to be feasible is the electrode material that has to allow ion mobility.In this review, electrode materials for Al-ion batteries, namely different cathodes are discussed. Furthermore, their performance is compared highlighting drawbacks and advantages of every material.Over the last decade, optimizing energy storage has become significantly important in the field of energy conversion and sustainability. As a result of immense progress in the field, cost-effective and high performance batteries are imperative to meeting the future demand of sustainability. Currently, the best performing batteries are lithium-ion based, but limited lithium (Li) resources make research into alternatives essential. In recent years, the performance of aluminium-ion batteries ha...

Due to their small footprint and flexible siting, rechargeable batteries are attractive for energy storage systems. A super-valent battery based on aluminium ion intercalation and deintercalation is proposed in this work with VO2 as cathode and high-purity Al foil as anode. First-principles calculations are also employed to theoretically investigate the crystal structure change and the insertion-extraction mechanism of Al ions in the super-valent battery. Long cycle life, low cost and good capacity are achieved in this battery system. At the current density of 50 mAg−1, the discharge capacity remains 116 mAhg−1 after 100 cycles. Comparing to monovalent Li-ion battery, the super-valent battery has the potential to deliver more charges and gain higher specific capacity.

“…As shown previously, the CIL electrolytes are electrochemically reactive with stainless steel electrodes, which can lead to false capacity measurements. 19 Thus the current collector on the cathode side in the present study was made of glassy carbon. The current collector on the anode side was composed of a copper rod, copper-plated spring, and copper disc.…”

“…Subsequently, electrochemical activity and apparent capacity at the cathode of the V 2 O 5 /Al cell were wholly attributed to a reaction between the CIL and the stainless steel current collector. 19 Given the great difficulties encountered in developing cathode materials that can reversibly insert divalent magnesium ions, 20 it is likely that the identification of a host for reversible insertion of trivalent aluminum will be an even greater challenge.…”

Rechargeable aluminum batteries with conducting polymers as positive electrodes

This report is a summary of research results from an Early Career LDRD project conducted from January 2012 to December 2013 at Sandia National Laboratories. Demonstrated here is the use of conducting polymers as active materials in the positive electrodes of rechargeable aluminum-based batteries operating at room temperature. The battery chemistry is based on chloroaluminate ionic liquid electrolytes, which allow reversible stripping and plating of aluminum metal at the negative electrode. Characterization of electrochemically synthesized polypyrrole films revealed doping of the polymers with chloroaluminate anions, which is a quasi-reversible reaction that facilitates battery cycling. Stable galvanostatic cycling of polypyrrole and polythiophene cells was demonstrated, with capacities at near-theoretical levels (30-100 mAh g -1 ) and coulombic efficiencies approaching 100%. The energy density of a sealed sandwich-type cell with polythiophene at the positive electrode was estimated as 44 Wh kg -1 , which is competitive with state-of-the-art battery chemistries for gridscale energy storage. 4 ACKNOWLEDGMENTS
