| 摘要 |
A non-circular electrochemical cell (10) with a housing (20) having an elongated surface, an anode (40) containing lithium, a cathode (62) containing manganese dioxide, and a nonaqueous electrolyte wherein the anode and cathode are spirally wound. In one embodiment the cell has overall dimensions of length, width and thickness about the same as the overall dimensions of two AA size alkaline cells placed in side by side arrangement with edges aligned. In such configuration the cell of the invention can be used in place of two AA alkaline cells in high power electronic devices, such as digital cameras, which were designed to house two AA alkaline cells in side by side arrangement, and electrically connected in series. The cell of the invention preferably has a cross section, taken perpendicular to its central longitudinal axis, which is of elliptic or approximately elliptic shape. |
