20120088028 | Process for Producing a Positive Nickel Hydroxide Electrode for a Nickel-Metal Hydride or Nickel Cadmium Storage Battery - In a process for producing a positive nickel hydroxide electrode for a nickel-metal hydride or nickel-cadmium storage battery a positive nickel hydroxide electrode produced in an earlier stage in the process is after-treated by introducing a saline solution into the active mass contained in an electrode carrier structure of the electrode in order to obtain a positive nickel hydroxide electrode with an improved current yield. | 04-12-2012 |
20120077061 | Nickel-Metal Hydride Accumulator - A nickel-metal hydride accumulator for industrial applications has positive nickel hydroxide electrodes and, separated therefrom, negative metal hydride electrodes as well as an alkaline electrolyte surrounding the electrodes. An improved nickel-metal hydride accumulator that is in particular insensitive to influences of temperature has a thermal arrangement which increases the specific thermal capacity of the accumulator and is formed by an additional electrolyte volume, wherein the accumulator comprises a plastics material housing which receives the electrodes and the electrolyte and is provided with a pressure relief valve. | 03-29-2012 |
