Alkaline cell battery and method for manufacture thereof
First Claim
1. In a cell for an alkaline battery of the type having a positive electrode, a negative electrode in the form of a paste contained within a sealed bag, a dielectric positioned at least between the electrodes, a flexible package in which the electrodes and dielectric are sealed and a pointed conductor connected to the positive electrode of the cell and adapted to pierce the package and the negative electrode bag of an adjacent cell to make electrical contact with the negative electrode paste of such cell when the cells are pressed together, thereby electrically connecting the two cells;
- a structure for enhancing sealing for the pierced cell comprising;
a supportive plate for inhibiting denting of the negative electrode bag and the package adjacent thereto of the pierced cell by the pointed conductor when the cells are pressed together; and
means for mounting said plate to the negative electrode side of said package.

Abstract
This invention relates to a cell construction for alkaline batteries, to alkaline batteries utilizing such cells and to methods for the manufacture thereof. Each cell has a positive electrode, a negative electrode in the form of a paste contained within a sealed bag, and a dielectric positioned at least between the electrodes. The electrodes and dielectric are sealed within a flexible package and a pointed conductor is provided which is electrically connected to the positive electrode of the cell, extends therefrom, and is adapted to pierce the package and negative electrode bag of an adjacent cell to make electrical contact with the negative electrode paste of such cell when the cells are pressed together to form a battery. The invention provides improved sealing between the cells by inhibiting the denting of the packaging and negative electrode bag prior to piercing by use of a stiff supporting plate mounted to the negative electrode side of the cell. This plate may be mounted inside or outside the cell cover and is adapted to be pierced by the pin when the cells are pressed together. A suitable adhesive such as hot melt glue may be provided to secure the plate to the cell and to seal the openings caused when the pin pierces the various layers.
