An anodic stripping voltammetry (ASV) sensing platform which provides real time determination of zincate diffusion through membrane separators in alkaline electrolyte with total experimental times on the order of hours is presented. Advanced separators are essential for future rechargeable alkaline zinc batteries. In order to be screened, these membranes need to be evaluated for their zincate blocking performance. Current complexometric titration and elemental analysis methods for zincate membrane diffusion characterization can take days to weeks to obtain results as well as include large sample dilution factors and require additional sample processing. The anodic stripping voltammetry (ASV) sensing platform presented here provides real time determination of zincate diffusion in alkaline electrolyte with total experimental times on the order of hours. This method eliminates the need for sample dilution and post experiment sample processing. This technique significantly increases the throughput for the screening of advanced alkaline battery separators resulting in rapid turnaround times in the analysis of these vital membranes. To evaluate the utility of this method, zincate diffusion through commercial Celgard 3501 and Cellophane 350P00 was monitored using both ASV and inductively coupled plasma‐mass spectrometry (ICP‐MS) methods. The obtained zincate diffusion coefficients for both techniques were found to compare favorably.

Regenerable Cu-intercalated MnO2 layered cathode for highly cyclable energy dense batteries

Manganese dioxide cathodes are inexpensive and have high theoretical capacity (based on two electrons) of 617 mAh g−1, making them attractive for low-cost, energy-dense batteries. They are used in non-rechargeable batteries with anodes like zinc. Only ∼10% of the theoretical capacity is currently accessible in rechargeable alkaline systems. Attempts to access the full capacity using additives have been unsuccessful. We report a class of Bi-birnessite (a layered manganese oxide polymorph mixed with bismuth oxide (Bi2O3)) cathodes intercalated with Cu2+ that deliver near-full two-electron capacity reversibly for >6,000 cycles. The key to rechargeability lies in exploiting the redox potentials of Cu to reversibly intercalate into the Bi-birnessite-layered structure during its dissolution and precipitation process for stabilizing and enhancing its charge transfer characteristics. This process holds promise for other applications like catalysis and intercalation of metal ions into layered structures. A large prismatic rechargeable Zn-birnessite cell delivering ∼140 Wh l−1 is shown.

“…Therefore we are researching development of a flow battery that does not require a membrane, so that the membrane may be eliminated, eliminating those problems associated with the membrane. This can reduce the cost of the battery significantly; cost estimates and bill of materials of a no-membrane flow battery are given in Turney et al [16]. This reduces the cost of the batteries significantly, even though they are operated at current densities below 40 mA cm À2 : the current densities of soluble lead acid batteries (SLABs) [17], zinc-bromine batteries (ZBBs) [18] and zinc-nickel batteries (ZNBs) [19] are operated below 20 mA cm À2 .…”

“…In addition, the raw materials of the zinc/nickel battery are in rich and environmental friendly. Research on this system have spanned from lab bench top systems demonstrating 3000+ cycles to 30 kWh grid-sized systems demonstrating 1100+ cycles [16], yet in both cases its performance is limited by poor cycling characteristics of the zinc anode and swelling of the nickel cathode. The short cycle life of the zinc anode arises mainly from dendritic growth (in the anode ZnðOHÞ 2À 4 ¼ ZnO þ H 2 O þ 2OH À ) and the shape change in the zinc electrode during charging.…”
