Latest Patents
Tamagawa's latest patents include a nickel electrode for alkaline storage batteries and a method of manufacturing the same. The nickel electrode is designed by filling a conductive porous member with an active material that primarily consists of nickel hydroxide, incorporating cobalt in a solid solution. Additionally, a compound layer is formed on the surface of the main active material layer, which includes elements such as calcium, aluminum, strontium, scandium, yttrium, and lanthanides. The specific metal molar ratios of cobalt to nickel and the elements in the compound layer are carefully controlled to enhance battery performance.
The method of producing the nickel electrode involves several steps, including preparing an active-material loaded plate electrode, immersing it in an impregnation solution, and conducting an alkali treatment to form a hydroxide layer. This innovative approach ensures that the nickel electrode maintains its capacity and exhibits excellent high-temperature characteristics.
