(US5168018-A)      Mfg. a Zn-alkaline battery comprises dispersing a Zn alloy powder as an active material in a gel-like alkaline electrolyte to prepare a gel-like anode. The Zn alloy contains at least one alloying element selected from In, Pb, Bi, Li, Ca and Al and the electrolyte contg. indium hydroxide or indium sulphide prepd. from an In salt as starting material by neutralising an aq. soln. of the salt, the In hydroxide or sulphide being contained in an amt. of 0.005-0.5 wt.% based on the wt. of the Zn alloy. The Zn alloy pref. contains 0.01-1 wt.% In and 0.005-0.5 wt.% in total of one or two of Pb and Bi is used as the anode active material. The Zn alloy may further contain a surfactant having a hydrophilic part of polyethylene oxide and an oleophilic part of a fluoroalkyl gp. in an amt. of 0.001-0.1 wt.% based on the wt. of Zn alloy e.g. (X)-CnF2n-(Y)-(CH2CH2O)m-(Z) where X = H or F; Y = C2H4OCH2CH(OH)-CH2O-, -CONH or -SO2NR where R = H or alkyl; Z = -CH3, PO3W2 or SO3W where W = alkali metal; n = 4-10; m = 20-100.    USE/ADVANTAGE -   The Hg-free Zn-alkaline batteries have no adverse effect on the environment and have an excellent shelf stability and discharge property.    (JP2754865-B2)      Mfr. of a zinc-alkaline battery is claimed. It comprises dispersing a zinc alloy powder as an active material in a gel-like alkaline electrolyte to prepare a gel-like anode. The zinc ally contains at least one alloying element of indium, lead, bismuth, lithium, calcium or aluminium. The alkaline electrolyte contains indium hydroxide or indium sulphide prepd. by neutralising an aq. soln. of an indium salt, the indium hydroxide or sulphide is contained in an amt. 0.005-0.5 wt.% based on wt. of zinc alloy. Opt. the battery also contains a hydrophilic part of polyethylene oxide and an oleophilic part of a fluoroalkyl gp. in amt. 0.001-0.1 wt.% based on wt. of the ' zinc alloy.    ADVANTAGE -   The batteries have no adverse effect on the environment and have a good shelf stability and discharge property.    (JP2808822-B2)      Mfr. of a zinc-alkaline battery is claimed.
