Sealed secondary alkaline battery: Sealed secondary alkaline battery. (Sanyo Electric Co., Ltd., Japan). Jpn. Tokkyo Koho JP 58031706 B4 7 Jul 1983 Showa, 3 pp. (Japanese). (Japan). CODEN: JAXXAD. CLASS: IC: H01M010-52. APPLICATION: JP 75-93624 30 Jul 1975. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) A H-ionizing and diffusing Ni or Ni-compd. electrode is connected with a Co electrode to control the voltage of the 1st electrode at -0.3 to -0.8 V (ref. std. H electrode). The electrode is used in the storage-stable title battery with Ag cathodes or Zn and Fe anodes. There are some commonly used reagents like 7440-48-4 in this article. Thus, a powd. (300-350 mesh) sintered Co on Ni-plated Fe plate was connected via a wire with a Ni electrode. A battery using the connected electrode for H ionization showed a neg. internal pressure after 3-mo storage vs. ~30 kg/cm2 for a conventional battery with unconnected Ni electrode. .

Tokkyo Koho JP 58031705 B4 7 Jul 1983 Showa, 3 pp. (Japanese). (Japan). CODEN: JAXXAD. CLASS: IC: H01M010-52. APPLICATION: JP 75-93623 30 Jul 1975. DOCUMENT TYPE: Patent CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) A H-ionizing and diffusing electrode with -0.3 to -0.8 V in ref. to std. H electrode is prepd. by depositing Co on a sintered Ni or Ni-compd. plate, and the prepd. electrode is used in the storage-stable title battery with Ag cathodes or Zn and Fe anodes. Thus, a powd. Ni sintered plate was electrochem. treated in an aq. soln. of CoSO4.7H2O (50 g Co/L) at 20-25°, pH 6-7, and 2 A (on 100 cm2 apparent surface area) for 1 h. A battery using the Co-treated Ni electrode as a H-ionizing electrode showed a neg. internal pressure after 3-mo storage vs. ~30 kg/cm2 for a conventional battery with untreated Ni electrode. .
