Abstract
An electrode plate of a storage battery includes a rectangular, conducting, porous base plate and a paste containing an active substance, spread over the surfaces of the base plate , and filled in the hollow spaces in the base plate by rolling so as to form layers attached to the surfaces of the base plate . When shaping the base plate , the corners C of the base plate are rounded, and the edge of at least one of the sides S of the base plate is rounded in cross section. Thus, burrs at the corners C and along the sides S are removed so that the exertion of excessive contact pressure on the corners C and the sides S of the base plate is prevented in the assembled state of the storage battery, whereby the occurrence of short circuit is also prevented.
