Abstract
An electrode plate for a battery comprising a plurality of electrodes in a grid where the grid defines a plurality of spaces. A paste disposed in the spaces has a top surface and a bottom surface. The paste is narrowed in the space, defining a distance between the top surface of the paste and the bottom surface of the paste that is less than the thickness of the plate over the electrodes. A retention layer of porous fabric is impressed on the top and/or bottom surface of the paste. Electrolyte disposed in electric communication with the electrodes.
Claims32
An electrode plate for a battery comprising:
- a plurality of electrodes configured as a grid, said grid having a thickness measured perpendicularly to a longitudinal axis of said electrodes at the point of measurement;
- a plurality of spaces disposed between said electrodes of said grid;
- a paste disposed in said spaces, said paste having a top surface and a bottom surface;
- a narrowing of said paste in said space, said narrowing defining a distance between said top surface and said bottom surface measured in a direction parallel to said thickness of said grid, said distance being less than said thickness of said grid in an area of said grid adjacent to said narrowing;
- a retention layer attached to at least one of said top surface or said bottom surface with substantially none of said paste being on a side of said retention layer opposite the electrode;
- whereby upon assembly electrolyte may enter an area between said electrodes defined by said narrowing.
The plate of the previous claim wherein a top retention layer and a bottom retention layer touch each other in said throughhole.
A battery comprising:
- at least one positive plate;
- at least one negative plate;
- said plates being immersed in an electrolyte;
- further comprising at least one of said plates comprises:
- a plurality of electrodes configured as a grid, said grid having a thickness measured perpendicularly to a longitudinal axis of said electrodes at the point of measurement;
- a plurality of spaces disposed between said electrodes of said grid;
- a paste disposed in said spaces, said paste having a top surface and a bottom surface;
- a narrowing of said paste in said space, said narrowing defining a distance between said top surface and said bottom surface measured in a direction parallel to said thickness of said grid, said distance being less than said thickness of said grid in an area of said grid adjacent to said narrowing;
- a retention layer attached to at least one of said top surface or said bottom surface with substantially none of said paste being on a side of said retention layer opposite the electrode,
- said electrolyte being in an area between said electrodes defined by said narrowing.
