<p>1. A button-type activatable battery comprising, in a housing provided with a positive terminal and a negative terminal, a stack of components constituted by separators (70) and electrodes each constituted by a current collecting metal plate (10) having at least one of its faces coated with a positive or a negative active material, each plate having at least two openings via which the plates are threaded over two mutually parallel shafts, intermediate rings maintaining the desired gaps between the plates (10) by pressing against portions of the plates, with each ring being selected to be a conducting ring (25) or an insulation ring (86) depending on whether the ring is required to provide and electrical connection between the two electrodes corresponding thereto, and longitudinal locking means being provided on each of said shafts for locking said plates (10) and rings (25, 86), the battery being characterized by the fact that said shafts (83, 84) are made of insulating material, that they are hollow, that they open out sideways into electrolyte distribution channels (85) provided in the insulating intermediate rings (86), and that they are capable at one of their ends (87, 88) of communicating with a tank (90) of activating electrolyte.</p> |
