Abstract
A method for forming an electrode plate which includes an active portion pasted with active material and a plate head which includes a connection tab. The plate head is constituted by the same metal foam as the plate support, but the density of the metal foam in the plate head is not less than 2.5 times the density of the metal foam in the remainder of the electrode plate, the higher density of the plate head coming from an operation in which the foam of the support is compressed, the tab of the plate head emerging from the middle of the thickness of the plate and being derived from compression of the support in two directions: compression firstly in the direction of its height; and compression secondly in the direction of its thickness. Such an electrode plate is made from a plate of metal foam whose top edge is compressed so as to form the plate head. Compression takes place in the height direction and then in the thickness direction for the tab, and for the remainder of the length of the electrode, compression takes place at least in the height direction.
