Journal ArticleDOI
Some factors affecting the cycle lives of LaNi5-based alloy electrodes of hydrogen batteries
Tetsuo Sakai,Keisuke Oguro,Hiroshi Miyamura,Nobuhiro Kuriyama,Akihiko Kato,Hiroshi Ishikawa,Chiaki Iwakura +6 more
TL;DR: In this article, the effect of substituting elements to improve the cycle life increased in the order: M ≡ Mn, Ni, Cu, Cr, AlandCo, and the lower the capacity, the smaller the volume expansion ratio, the slower the pulverizing rate, and lower the Vickers hardness were.
Journal ArticleDOI
The anodic characteristics of manganese dioxide electrodes prepared by thermal decomposition of manganese nitrate
TL;DR: In this paper, a thermal decomposition of manganese nitrate solution on a titanium or a platinum substrate was investigated mainly in 1N H2SO4 and 1N KOH.
Journal ArticleDOI
Effects of Microencapsulation of Hydrogen Storage Alloy on the Performances of Sealed Nickel/Metal Hydride Batteries
Journal ArticleDOI
The influence of small amounts of added elements on various anode performance characteristics for LaNi2.5Co2.5-based alloys
Tetsuo Sakai,Hiroshi Miyamura,Nobuhiro Kuriyama,Akihiko Kato,Keisuke Oguro,Hiroshi Ishikawa,Chiaki Iwakura +6 more
TL;DR: The addition of small amounts of elements such as silicon, aluminium and titanium to LaNi2.5Co2 greatly influenced anode performance characteristics such as usable temperature range, capacity and its decay rate during repeated cycles, rate capability, low temperature dischargeability and self-discharge rate as discussed by the authors.
Journal ArticleDOI
The anodic characteristics of massive manganese oxide electrode
TL;DR: In this paper, the massive Mn oxides were synthesized and their anodic characteristics were investigated in aqueous solutions, and it was suggested that the oxidation process of the electrode surface is a common rate-determining step in both reactions on massive Mn oxide electrodes.
