Abstract
An end connector for a battery in which a set of interleafing battery plates is electrically and mechanically connected with a cast-on element to form a secure attachment with no discontinuities. The preferred embodiment utilizes a set of lead or lead alloy plates having an edge that is immersed into a mold of molten material that forms the end connector.
Claims41
A battery, comprising a first electrical plate having a first electrical polarity, a first electrical battery terminal, and a first end connector connected to the first terminal and cast onto the first plate with no discontinuities between the first end connector and first plate for establishing electrical communication between the first plate and first terminal.
A battery, comprising a first electrical plate having a first electrical polarity, and a first electrical battery terminal, wherein the first plate is spirally wound and has a spiral edge in substantially one edge plane, and a first end connector cast onto the first plate in said edge plane to establish electrical communication between the first plate and the first electrical battery terminal.
A battery , comprising a first electrical plate having a first polarity, a first electrical battery terminal, a second electrical plate, having a polarity opposite the polarity of the first electrical plate, and a separator to separate the first and second plates, the first and second plates and separator being spirally wound with said first plate spiral edge extending axially out of a first end of said spiral winding, and a first end connector connected to the first electrical battery terminal and cast onto the first plate spiral edge without electrically communicating with the second plate.
A method of making a battery, comprising arranging a set of anode and cathode plates divided by a separator, casting an end connector onto the plates with no discontinuities between the end connector and the plate by immersing an edge of said plates into molten metal that is at approximately the melting temperature of the metal whereby the plate edge is heated to approximately said temperature but is not melted to attach the plates to the end connector, and allowing the metal to solidify into an end connector with no discontinuities between the end connector and the plate.
