ABSTRACT:
An electrochemical cell (10) having a first electrode (20) and second electrode (80) and a separator (40) disposed therebetween further includes a layer of material disposed between at least one of the electrodes and the separator (52). The layer (52) is adapted to reduce the likelihood of cell failure by subduing the dendritic growth of at least one of the electrodes. The layer (52) is a layer of a metal mesh screen and may further be adapted to be used as the current collector for collecting current generated by the cell (10).
