  • Spherical nickel hydroxide powders coprecipitated with the additives Ca(OH){sub 2}, Co(OH){sub 2}, and Zn(OH){sub 2} were prepared through a spraying technique. These powders, which have a higher tapping density and a much smaller pore volume and crystalline size than conventional powders, were used as the active materials of nickel hydroxide electrodes. The effects of the Ca(OH){sub 2}, Co(OH){sub 2}, and Zn(OH){sub 2} additions on electrode properties such as charge-discharge, reversibility of the electrode reaction, and cycle life, were studied. The relationship between the electrode swelling and the formation of {gamma}-NiOOH was also investigated. The results show that nickel hydroxide powdersmore » having a smaller crystallite size show better electrode characteristics such as lower overpotential, higher plateau discharge potential, and higher capacity. The utilization of the active material in the electrodes illustrates that for general use it is better to add Co{sub 2+}, while for a wider temperature range, it would be better to consider the addition of Ca{sup 2+}. The cycle life of the electrode containing Zn{sup 2+} was improved obviously because there was less electrode swelling due to much reduced formation of {gamma}-NiOOH.« less
  • The price of the cathode active materials in lithium ion batteries is a key cost driver and thus significantly impacts consumer adoption of devices that utilize large energy storage contents (e.g. electric vehicles). A process model has been developed and used to study the production process of a common lithium-ion cathode material, lithiated nickel manganese cobalt oxide, using the co-precipitation method. The process was simulated for a plant producing 6500 kg day –1. The results indicate that the process will consume approximately 4 kWh kg NMC –1 of energy, 15 L kg NMC –1 of process water, and cost $23more » to produce a kg of Li-NMC333. The calculations were extended to compare the production cost using two co-precipitation reactions (with Na 2CO 3 and NaOH), and similar cathode active materials such as lithium manganese oxide and lithium nickel cobalt aluminum oxide. Finally, a combination of cost saving opportunities show the possibility to reduce the cost of the cathode material by 19%.« less
  • Here, an improved method for quantitative measurement of the charge transfer, finite diffusion, and ohmic overpotentials in redox flow batteries using electrochemical impedance spectroscopy is presented. The use of a pulse dampener in the hydraulic circuit enables the collection of impedance spectra at low frequencies with a peristaltic pump, allowing the measurement of finite diffusion resistances at operationally relevant flow rates. This method is used to resolve the rate-limiting processes for the V 2+/V 3+ redox couple on carbon felt and carbon paper electrodes in the vanadium redox flow battery. Carbon felt was limited by both charge transfer and ohmicmore » resistance, while carbon paper was limited by charge transfer, finite diffusion, and ohmic resistances. The influences of vanadium concentration and flow field design also are quantified.« less
