摘要： The present invention concerns a procedure for producing an envelope structure for a storage battery having a housing, a cover, and partitions separating cells therein. The battery in particular comprises one or several cells enclosed within the housing, with each cell containing electrolyte and monopolar plates and/or bipolar plates separated from one another by separator plates, and being coated with positive and/or negative active mass, in addition to the requisite electrical connectors interconnecting the cells and/or plates. The envelope structure of the storage battery is produced by casting with electrically-insulating an electrolyte-impermeable material, using in the casting the cells of the storage battery at an inner mold, and separately-constructed mold structure as an outer mold. Wall thickness of the housing of the storage battery is defined with the aid of a spacer structure remaining inside the cast.
