Abstract:
Die Erfindung beschreibt ein Speichermodul (1) zur Spannungsversorgung, insbesondere eines Kraftfahrzeugs, mit einer Anzahl an Speicherzellen (10, 11,..., 15), die jeweils ein erstes und ein zweites Anschlussterminal unterschiedlicher Polarität und ein Ventil (30, 31,..., 35) aufweisen, über das ein in einer Speicherzelle (10, 11 15) vorhandener Innendruck abgebaut werden und Elektrolyt der Speicherzelle (10, 11,..., 15) aus dieser austreten kann. Über die Anschlussterminals sind die Speicherzellen elektrisch zu dem Speichermodul (1) verschaltet. Eine saugfähige Schicht (50) ist zur Aufnahme und Bindung auslaufenden Elektrolyts benachbart zu dem und/oder im Bereich des Ventils (30, 31,..., 35) einer jeweiligen Speicherzelle (10, 11,..., 15) angeordnet.
Abstract:
The invention concerns a cover (1, 101, 102, 103, 104, 105) for an electric accumulator (100) adapted to be integral with the container (2) of the accumulator (100) and a relative accumulator (100). The cover (1, 101, 102, 103, 104, 105) comprises: a reservoir (6), adapted to contain a topping up liquid (R) of the electrolyte (E) present in the cells (4) of the accumulator (100), communicating through a supply duct (7) with the cells (4); control tneans (9) of the level (L) of the electrolyte (E) in the cells (4) adapted to prevent/allow the flow of topping up liquid (R) when the corresponding level (L) of the electrolyte (E) is higher/lower than a predetermined level (S).
Abstract:
In one embodiment, a refuelable and rechargeable metal air electrochemical cell includes a removable and rechargeable metal fuel anode, and air cathode, a third electrode, and a separator in ionic communication with at least a poriton of a major surface of the anode. In another embodiment, a refueable and rechargeable metal air electrochemical cell includes a discharging cell and a recharging cell. The discharging cell includes an air cathode structure adapted to receive a removable and rechargeable metal fuel anode that, when inserted in the air cathode structure, produces electrical energy during the process of electrochemical conversion of the metal fuel into a metal oxide. The recharging cell includes a charging electrode structure adapted to receive the removable and rechargeable metal fuel anode (generally after such anode has been discharged, or prior to initial usage of the anode for discharging), that, when inserted in the charging electrode structure, converts the metal oxide into metal fuel upon application of electrical energy. Furthermore, various structures are provided that facilitates reducing of the anode.
Abstract:
A vent system for exhausting gas generated within a battery case is provided. The vent system exhausts gas from the battery case while maintaining the hermetic seal of the case. The vent system provides a small gas exit hole that is sufficiently small to prevent electrolyte leakage and also intake of excess carbon dioxide or excess water vapor from the atmosphere. Also, various combinations of gas-permeable, hydrophobic membranes and diffuser material may cover the gas exit hole to provide humidity control for the battery while exhausting gases from the battery. A recess may be provided within the case such that the gas exit hole communicates between the atmosphere and the recess. Also, various combinations of gas-permeable, hydrophobic membranes and diffuser material may cover the recess and gas exit hole to provide humidity control for the battery while exhausting gases from the battery case. The present invention also provides a vent system in which gas-permeable, hydrophobic membranes and diffuser material may fill an opening so as to exhaust gas from the case. The present invention also provides an electrode lead which extends along the battery case and through the seam of the battery case in a manner in which a hermetic seal is provided around the lead. The manufacturing process for the seal around the lead is relatively simple.
