Description

ABSTRACT:
An electrochemical cell of the limited electrolyte type is described having a cell pack comprised of the normal absorbent separator interleaved and compressed between positive and negative plates, the electrolyte absorbed within pores of the separator and plates, and a container encasing the cell pack. The cell pack has an edge or edges which abut against at least one wall portion of the container, forming an interface in which is formed channels providing passageways which promote uniform distribution of electrolyte within the cell pack at least during filling of the cell with electrolyte. Filling time is also substantially reduced.
