  Nickel electrodes made using lightweight plastic plaque are about half the weight of electrodes made from state of the art sintered nickel plaque. This weight reduction would result in a significant improvement in the energy density of batteries using nickel electrodes (nickel hydrogen, nickel cadmium and nickel zinc). These lightweight electrodes are suitably conductive and yield Cited by: 2. A method for fabricating lightweight nickel electrodes has been developed by electrochemical impregnation of two different nickel fiber substrates. The electrochemical impregnation technique was applied galvanostatically at 35–50 mA/cm 2 in acidic solutions of nickel and cobalt nitrates (pH = 3). The nickel and cobalt contents of impregnated and formed electrodes was analyzed with atomic Cited by: 8.   A method for fabricating lightweight nickel electrodes has been developed by electrochemical impregnation of two different nickel fiber substrates.

Britton. Abstract. The NASA Lewis Research Center is currently developing nickel electrodes for nickel-hydrogen (Ni-H2) cells and batteries. These electrodes are lighter in weight and have higher specific energy than the heavy sintered state of.

A lightweight nickel hydroxide electrode was obtained through developing a stable α-phase nickel hydroxide with a 10 at. % Al substitution. The effects of an Al addition within 10−30 at. % on the interslab distance of the () plane as well as on the electrochemical properties were investigated. Pasted α- and β-type nickel hydroxide electrodes were fabricated to compare the specific. The NASA Lewis Research Center is currently developing nickel electrodes for nickel-hydrogen (Ni-H2) cells and batteries. These electrodes are lighter in weight and have higher specific energy than the heavy sintered state of the art nickel electrodes. These electrodes are lighter in weight and have higher energy densities than the heavier state-of-the-art (SOA) sintered nickel electrodes. In the present approach, lightweight materials or plaques are used as conductive supports for the nickel hydroxide active material.   Now two researchers from the S.N. Bose National Centre for Basic Sciences, India, have developed a novel supercapacitor electrode based on a hybrid nanostructure made from a hybrid nickel oxide-iron oxide exterior shell and a conductive iron-nickel core.

  A high‐performance and low‐cost pasted nickel electrode made from a metal fiber substrate has been developed. The electrode is designed so that it exhibits active material utilization close to %, with an energy density as high as mAh/g or mAh/cm high active material utilization, even with a metal fiber substrate, which is a poor current collector compared with a.   Posted: High performance, lightweight supercapacitor electrodes of the future (Nanowerk News) As a novel energy storage device, supercapacitors have attracted substantial attention in recent years due to their ultra-high charge and discharge rate, excellent stability, long cycle life and very high power e charging your cell phone in just a few seconds or fueling up. Development of a high specific energy battery is one of the objectives of the lightweight nickel-hydrogen (Ni-H 2) program at the NASA Glenn Research Center. The approach has been to improve the nickel electrode by continuing combined in-house and contract efforts to develop a lighter weight electrode for the nickel-hydrogen cell. A method for fabricating lightweight nickel electrodes has been developed by electrochemical impregnation of two different nickel fiber substrates. The electrochemical impregnation technique was applied galvanostatically at mA/cm 2 in acidic solutions of .
