Herstellungsmethode einer Batterie

摘要

A method of manufacturing a battery which comprises a first electrical plate (20; 120; 310) having a first electrical polarity, a first electrical battery terminal (26;160), and a first end connector (24; 162) for establishing electrical communication between said first electrical plate (20; 120; 310) and said first electrical battery terminal (26; 160), said first end connector (24; 162) being connected to said first electrical battery terminal (26; 160) and cast onto said first electrical plate (20; 120), characterised in that said casting is carried out by immersing an edge of said first electrical plate in a mould containing molten metal which has a heat content substantially such that the addition of heat will result in an increase in temperature of the molten metal whilst the subtraction of heat will result in the formation of a mixture of solid and molten metal, whereby by drawing a graph in which the ordinate represents the temperature of said metal and the absiscae represents heat input so as to define a first portion (A) in which the temperature of the solid metal rises as heat is added to it, followed by a plateau portion (B) where heat is utilised to melt the solid metal without materially increasing the temperature of the solid/liquid mixture, and a third portion (C) having an incline and representing an increase of the temperature of the melt as heat is added to it, the plate is submerged in the molten metal when its heat content is such, that it corresponds to a point, which is close to the boundary between the plateau portion (B) and the incline of the third portion (C).
