    Abstract: The invention describes alloyed zinc powders for alkaline batteries. The powders have a high pyknometer density as a consequence of the presence of only a limited quantity of pores. This high pyknometer density results in strongly reduced gassing after partial discharge of the powders. Also, a process for the manufacturing of a zinc alloy powder for alkaline batteries is disclosed, comprising the step of atomising a zinc alloy, characterised in that the atomising process has a flow rate of at least 700 kg/h, and preferably at least 1000, 1100 or even 1650 kg/h. In one embodiment, the atomising process is performed in a controlled atmosphere, wherein the oxygen content is less than 4 % by volume, and preferably between 0.2 and 3.5 %. The atomising process can be a centrifugal atomisation process. In the atomising process, the zinc alloy consists either of: a) 0.005 - 2 % by weight of indium, and 0.005 - 0.2 % by weight of either one of Al and Bi; or b) 0.005 - 2 % by weight of indium, and 0.005 - 0.2 % by weight of Bi, and 0.001 - 0.5 % of either one or both of Al and Ca; or c) 0.005 - 2 % by weight of either one or both of Bi and Al; and 0 - 0.5 % by weight of Pb, the remainder being zinc.

    Abstract: A negative electrode material for a nonaqueous electrode secondary battery which comprises alloy grains comprising grains of Si phase (40) and, surrounding at least a part of each thereof, a solid solution or a phase of an intermetallic conpound of Si with another element selected from the group consisting of the elements belonging to Group 2A, the transition metal, Group 3B and Group 4B of the long term Periodic Table (for example, NiSi2 phase (42) and [NiSi2 + NiSi] phase (41)), and have an average particle diameter of 0.1 to 50 mu m, the grains of Si phase accounting for 5 to 99 wt.% of the material. The alloy grain can be produced by rapid solidification (for example, atomization or roll quenching) of a melt containing Si and another element mentioned above, or, by a method comprising subjecting a Si powder to electroless plating or mechanical alloying, to thereby deposit the other metal thereon and then subjecting the resultant product to heat-treating. This negative charge material can be used for producing a battery having a high discharge capacity and a long lifetime under the condition of use of repeating the charge-discharge cycle. Employment of a rapid solidification method allows the production of such an excellent material with no heat-treatment.
