Title: Button type alkaline battery
Inventor: TSUCHIYA KAZUHIRO
IPC: H01M4/42
Filed: 1982-12-27
Abstract: PURPOSE:To prevent bulging and rupture of a battery by adding an element which is difficult to generate passivation to zinc of negative active material in a button type alkaline battery. CONSTITUTION:In a button type alkaline battery using Zn as a negative active material 1, MnO2, Ag2O, or AgO as a positive active material 2, and KOH or NaOH as an electrolyte 3, several percent of an element such as Pb which is difficult to generate passivation is added to Zn of the negative active material 2. The adding element is selected from substance having higher standard single electrode potential than Zn and standard hydrogen electrode potential near zero volt. When reaction of Zn is discontinued by passivation, reaction of Pb added starts. Thereby, even if the passivation of Zn is generated, evolution of oxygen gas is prevented. Therefore, bulging of a battery is prevented.

Abstract: PURPOSE:To obviate the generation of cracks, etc., in the Faraday rotor by taking out a single crystal which does not crack in the state in which a flux is dissolved. CONSTITUTION:The single crystal which grows and does not crack in the state in which the flux is dissolved. Raw materials and the flux are mixed in the range of 4.5 to 9.1mol% Gd2O3, 37 to 46mol% Fe2O3, 36 to 50mol% Bi2O3 and 5.5 to 23.5mol% B2O3 to grow bismuth-substd. gadolinium iron garnet.

The dissipation of the heat from the Faraday rotor is prevented in this way and the growth of the Faraday rotor in the soln. is enabled. The generation of the cracks, etc., in the Faraday rotor is thus obviated.
