Abstract:
A metal support disk (10) for an electrochemical cell seal exerts a resilient outward radial force against the seal to maintain seal integrity over a wide range of operating temperature and, at the same time, exerts an upward force against the bottom of the metal end cap terminal of the cell to assure electrical contact between the anode inside the cell and the terminal. The disk includes a central, circular platform (14) connected to an outer, sealing edge sealing flange (28) by an annular flexure means which permits radially inward and outward movement of the sealing edge (30) when the end of the cell is radially crimped during the sealing process. The crimping also moves the central portion (12) of the disk up which results in the upward force being exerted against the end terminal. The flexure means is a sequential series of three annular, curved ribs with the first (20) and third (26) curved downward and the second (24) curved upward. A ring (22) depending radially outward and at an upward angle from the first rib connects the first rib to the second rib and helps to prevent plastic deformation of the disk sealing.
Abstract:
The present invention is an improved alkaline cell (10) wherein the capacity of each of the anode (20) and cathode (16) is at least 0.48 and more preferably at least 0.5 ampere-hour per cm of internal cell volume. This is achieved by employing zinc densities of at least 1.4 grams of zinc per cm of anode volume and manganese dioxide densities of at least 2.7 grams per cm of cathode volume.

Abstract:
The present invention relates to an electrochemical cell (10) and an integrally related state of charge indicator. The state of charge indicator has two electrical contacts (14, 16) and a display means connected therebetween. A first contact (14) is connected to a first cell terminal (22) and a second contact (16) is unconnected to either terminal. A switch means (20) permits electrical connection of the second contact (16) to the second terminal to visually (26) indicate the condition of the battery by the display means.
