Abstract
The method for reusing current collectors/distributors is employed in an electrochemical generator () comprising a multiplicity of elementary cells () assembled in a filter-press configuration and comprising an array of conductive sheets () and of current collectors/distributors (). The method of the invention provides dissembling the electrochemical generator () once the presence of a damaged elementary cell () is detected. Subsequently, the method of the invention provides repairing/replacing the damaged cell for later reassembling the electrochemical generator () reusing the original current collectors/distributors (). to achieve this, while reassembling the electrochemical generator (), a mechanical means for adapting () is inserted between each conducting sheet () and the respective current collector/distributor (). Such mechanical means may consist in metallic meshes, metallic textiles, interwoven fibers, foraminous sheets or expanded sheets, thin sealing gaskets, sealing gaskets provided with sealing rings on a surface thereof, sealing gaskets made of an elastic material with low elasticity modulus.
