Abstract

L'invention concerne des dispositifs électrochimiques à base de lithium qui contiennent au moins deux électrodes poreuses pourvues de microgrilles en métal déployé revêtues de matériaux actifs, ces électrodes étant séparées par un séparateur en thermo-mousse disposé en contact d'adhérence avec une électrode. Une colle organique conductrice d'ions est appliquée sur ledit séparateur en contact d'adhérence avec la seconde électrode. Un électrolyte non aqueux est immergé dans les électrodes et le séparateur, le dispositif étant enfermé dans une enceinte avec deux bornes extérieures.
