Abstract

La présente invention concerne un nouvel électrolyte solide et un procédé d'utilisation de celui-ci pour un processus de formation d'une batterie au plomb. Ledit électrolyte solide utilisé pour le processus de formation d'une batterie au plomb comprend de 75 à 86 % en poids de sulfate de calcium, de 9 à 12 % en poids d'acide sulfurique, et de 5 à 16 % en poids de stabilisant. Ladite batterie reçoit une charge de formation avec un capot supérieur non fermé après avoir introduit ledit électrolyte de manière uniforme entre les plaques de ladite batterie. La charge de formation de ladite batterie au plomb à l'aide de l'électrolyte solide de la présente invention peut réduire la quantité d'évacuation de gaz et de brume acide, qui provoquent un phénomène de pollution, de 4 à 8 % par rapport à la charge de formation d'une batterie au plomb normale. L'électrolyte solide utilisé pour la charge de formation peut être utilisé tel quel, puis peut être changé.
