Abstract[English]
A method of preparing a battery, the method comprising the steps providing a battery housing comprising a formation vent; adding an electrolyte to the battery housing to form a battery; retaining the electrolyte within the battery housing for a period; and applying charge across the pair of electrodes to thereby pre-charge the battery; wherein gas generated within the battery housing during the retaining step and pre-charging step is vented out of the battery housing through the at least one hole. Batteries formed by the method and formation vents included in the batteries are also described.[French]
La présente invention concerne un procédé de préparation d'une batterie, le procédé comprenant les étapes consistant à fournir un boîtier de batterie comprenant un évent de formation; ajouter un électrolyte au boîtier de batterie pour former une batterie; retenir l'électrolyte à l'intérieur du boîtier de batterie pendant une période; et appliquer une charge à travers la paire d'électrodes pour ainsi précharger la batterie; le gaz généré à l'intérieur du boîtier de batterie pendant l'étape de retenue et l'étape de précharge étant évacué du boîtier de batterie à travers le ou les trous. L'invention concerne également des batteries formées par le procédé et des évents de formation inclus dans les batteries.
