Beschreibung
Zusammenfassung:	1,223,502. Aluminium battery. FURUKAWA DENCHI K.K. 31 Oct., 1968 [31 Oct., 1967; 17 June, 1968], No. 51754/68. Heading HlB. A battery having an aluminium or aluminium alloy anode has an alkaline electrolyte containing a plumbite having a general formula of M 2 Pb(OH) 4 , MPb(OH) 4 or M 2 [Pb(OH) 4 ] 3 , a plumbate of the general formula M 2 Pb(OH) 6 , MPb(OH) 6 or M 2 (Pb(OH) 6 ] 3 or a stannate of the general formula M 2 Sn(OH) 6 , MSn(OH) 6 or M 2 [Sn(OH) 6 ] 3 , where M is a metal e.g. Na, K, Li, Zn or Al, in such a quantity as to inhibit self-corrosion of the electrode and enhance the current efficiency of the battery. A maximum current efficiency is obtained using 0.005-0.01 M potassium plumbite or plumbate or 0À05-0À1 M sodium stannate. The battery can be of the type Al-oxygen, Al-air, Al-NiOOH, Al-MnO 2 , Al-AgO.
