Abstract
Structure de joint destinée au remplissage avec un électrolyte et à la formation d'un électrolyte et batterie Sont décrits une structure de joint destinée au remplissage avec un électrolyte et à la formation d'un électrolyte et une batterie. La structure de joint destinée au remplissage avec un électrolyte et à la formation d'un électrolyte comporte une plaque de couvercle de batterie munie d'un orifice de remplissage destiné à un électrolyte ; un bouchon de fermeture configuré pour fermer et sceller l'orifice de remplissage avec un électrolyte en passant à travers l'orifice de remplissage avec un électrolyte ; et une fixation placée dans l'orifice de remplissage avec un électrolyte et sur le bouchon de fermeture et soudée à la plaque de couvercle de batterie. De cette façon, la fuite d'électrolyte peut être évitée efficacement et le rendement de la batterie peut être assuré. Figure pour l'abrégé : Fig. 1Joint structure for filling with an electrolyte and forming an electrolyte and battery A joint structure for filling with an electrolyte and forming an electrolyte and a battery is described. The joint structure for filling with an electrolyte and forming an electrolyte has a battery cover plate provided with a filling port for an electrolyte; a closure cap configured to close and seal the electrolyte fill port by passing through the electrolyte fill port; and a fastener placed in the electrolyte filling port and on the closing cap and welded to the battery cover plate. In this way, electrolyte leakage can be effectively avoided and battery performance can be ensured. Figure for abstract: Fig. 1
