Abstract
A battery plate for a lead acid battery includes a grid having a plurality of interconnected wires, an electro-chemically active material paste applied to the grid, at least one reinforcing member disposed in the paste, and the paste is cured. Preferably the reinforcing member is embedded in the active material, provides structural support for the active material and reduces the likelihood that in use the active material paste will shed from the grid.
Claims25
A battery plate for a lead acid battery, comprising:
- a grid including a plurality of interconnected wires, and a plurality of open spaces defined between at least some of the wires;
- an electro-chemically active cured paste carried by the grid in at least some of the open spaces, covering at least some of the wires and having outer faces;
- and
- at least one separate reinforcing member of a separate thin sheet of reinforcing material including reinforcing glass fibers which separate sheet is permeable to uncured paste, separate from the uncured paste prior to the uncured paste being applied to the sheet of material and grid, when applied the uncured paste flows into the sheet of material and open spaces of the grid and in the cured paste the separate sheet of reinforcing material is firmly and permanently embedded in and fixed in one of the outer faces of the cured paste generally parallel to the outer face and the separate sheet structurally supports the cured paste and reinforces the cured paste and the grid and is a separate sheet embedded and fixed in the outer face of the cured paste when the battery plate is in a lead acid battery.

A lead acid battery, comprising:
- a housing;
- at least one battery cell carried by the housing and having at least one positive plate and at least one negative plate, at least one plate including a grid having a plurality of interconnected wires and a plurality of open spaces defined between at least some of the wires,
- an electro-chemically active cured paste carried by the grid in at least some of the open spaces and covering at least some of the wires, and
- a separate reinforcing member of a thin sheet of reinforcing material having reinforcing fibers and the sheet of material is porous and permeable to uncured paste, separate from the uncured paste prior to the uncured paste being applied to the sheet of reinforcing material and the grid, and when applied the uncured paste flows into the separate sheet of reinforcing material and open spaces of the grid and in the cured paste the sheet of material is firmly embedded in and permanently fixed in the cured paste and extends generally parallel to the grid and in the battery remains a separate sheet of reinforcing material embedded and fixed in the outer face of the cured paste and reinforces the cured paste and the grid and retains the cured paste on the plate.

- an electro-chemically active cured paste carried by the grid in at least some of the open spaces, covering at least some of the wires and having outer faces;
- and
- at least one separate reinforcing member of a separate thin sheet of reinforcing material including overlapped reinforcing glass fibers which separate thin sheet is permeable by uncured paste, separate from the uncured paste prior to the uncured paste being applied to the sheet of material and grid, when applied the uncured paste flows into the sheet of material and open spaces of the grid and in the cured paste the separate sheet of reinforcing material is firmly and permanently embedded in and fixed in one of the outer faces of the cured paste generally parallel to the outer face and the separate sheet structurally supports the cured paste and reinforces the cured paste and the grid and remains as a separate sheet embedded and fixed in the outer face of the cured paste when the battery plate is in use in a lead acid battery.

A method of making a battery plate for a lead acid battery, comprising the steps of:
- providing a battery grid having a plurality of interconnected wires, and a plurality of open spaces defined between at least some of the wires;
- applying an electro-chemically active uncured paste to the grid in at least some of the open spaces covering at least a portion of the grid wires with the uncured paste;
- disposing a separate reinforcing member with glass fibers and permeable by uncured paste in the uncured paste generally parallel and adjacent to an outer face of the plate;
- and
- curing the uncured paste to fix the reinforcing member in the cured paste.
