Abstract
A lithium accumulator with a housing comprising at least one cell with two electrodes (2a, 2b) provided with current collectors (3a, 3b) and separated by a separator (4) wherein each electrode (2a, 2b), free of organic binders, is pressed down onto both sides of the current collector (3a, 3b) made of a perforated metal strip in the form of metal network, expanded meal or perforated metallic foil. The minimum thickness of the electrodes (2a, 2b) is three times the thickness of the perforated metal strip (3a, 3b).
