“…3a, and exhibited a two redox peaks assigned to the Li + ion insertion/extraction reaction. The higher intensity of the peak belonging to the latter reaction, commonly found in V-based oxides [12,16], might be indicative of the instability of this compound under the conditions of the electrochemical measurements. Conclusive evidence in support of this argument was provided by the color change in the solution: from colorless (before the curve was recorded) to yellow (after the cyclic voltammogram was obtained), the color being typical of VO 2 + in aqueous solutions (see Fig.…”

“…Several years ago, the layered phase LiV 3 O 8 was proposed by Köhler et al [8] as anode material for these electrochemical devices. Recently, Wu and coworkers have emphasized the suitability of this compound against a wide variety of cathodic materials such as LiCoO 2 [9,10], LiMn 2 O 4 [11] and LiNi 1/3 Co 1/3 Mn 1/3 O 2 [12] . The results, however, were somewhat disappointing since the capacity faded continuously upon cycling.…”

“…Recently, an aqueous rechargeable batteries (ARLB) using lithium vanadium oxide (LiV 3 [25][26][27][28] as the cathode and aqueous solutions of lithium salts as the electrolyte was reported. It is evident that the electrochemical lithium intercalation reaction in aqueous electrolytes can be made possible by selecting appropriate transition metal oxides and electrolytes.…”

In aqueous electrolyte batteries, the salt concentration of the electrolyte affects the ionic conductivity, which will further affect the rate performance of the battery as well as the diffusion of reactive species that can cause self-discharge, particularly in thick electrode devices. To this end, we explored the implications of device performance using Na 0.44 MnO 2 cathode material, NaTi 2 (PO 4 ) 3 , anode material in a NaClO 4 -based aqueous solutions with molarities as high as 5. Experiments included physical property characterizations, cyclic voltammetry, and constant current charging/discharging methods. Preliminary results indicate that, in cells with thick electrodes (∼1mm), rate capability and electrode utilization increased significantly with higher molarity solutions: capacity at the 1.5 C rate increased 38% by increasing the salt concentration from 1 M to 5 M. At the same time the oxygen-related self-discharge phenomenon was diminished when using higher electrolyte molarities, though there was still measurable loss in capacity in in the electrodes. Irreversible capacity loss was observed to occur even in electrolytes with the lowest oxygen content, suggesting that self discharge and capacity loss are not necessarily causally related. Clean and renewable energy technologies will require low cost batteries. As such, aqueous electrolyte alkali-ion batteries are promising solutions for those applications where the constraints on energy density and weight are less rigid compared to mobile or portable applications. The use of an aqueous electrolyte offers several advantages, specifically for large-scale energy storage applications, compared with batteries that are based on organic electrolyte blends. Neutral pH aqueous electrolyte batteries are non-flammable, have fast internal ion transportation and have the promise of having a relatively lower manufacturing cost. However, the stability window of water limits the voltage of an aqueous cell. Researchers have found the practical stability window of aqueous electrolyte is wider than the theoretical limit due to the kinetic effect. [1][2][3][4][5] This enables the usage of materials such as LiMn 2 O 4 whose operating potential exceeds the thermodynamic limit of pure water in the aqueous system. 17 However, capacity fading of aqueous cells is often reported in the literature with different electrode material systems. 3,13,17,18 Dissolved oxygen reacting with inserted Li/Na ions was believed to be one of the causes for capacity fading.3 In our study, we closely examined the influence of dissolved oxygen on anode stability.To make aqueous electrolyte batteries economically viable, relatively thick electrode structures must be used. 5,19 Electrolyte with good ionic conductivity is then needed to support such thick format electrodes to enhance ion transport throughout the device, thereby reducing ionic polarization. To this end, it is of interest to probe the relationship between electrolyte salt content, ionic conductivity, and overall device stability. We elec...
