ABSTRACT:
A separator plate for the negative electrode of a lead-acid battery comprising a molded, synthetic plastic wall or planar member of generally rectangular configuration. A pair of like separator plates are vertically oriented in the battery casing to sandwich the negative electrode therebetween including juxtaposed retention mats common in such a negative electrode assembly. The sandwich provides a clear-through channel along opposite extremities of the electrode for flow of electrolyte. The sandwich assembly is maintained by means of cooperating locking and sealing formations integral with the separator plates of the assembly. Wrapping of the positive electrode thereby is rendered unnecessary when assembling the battery and enables automated assembly of the battery using the separator plate sandwich.
