Rechargeable lithium batteries are described comprising an airtight container, electrodes immersed in an electrolytic solution and spaced apart by means of one or more separators, electrical contacts connected to the electrodes and a means for sorbing harmful substances formed of a multilayer polymeric sheet comprised of an inner layer of a polymeric material containing particles of one or more getter materials for the sorption of the harmful substances, and at least one external protective layer of a polymeric material impermeable to the electrolyte, wherein all the polymeric materials are permeable to the harmful substances.

Rechargeable lithium batteries comprising means for the sorption of harmful substances in the form of a multilayer polymeric sheet

The present invention relates to a method for manufacturing HO composite sorbers consisting of a polymeric matrix in which hygroscopic inorganic salts are dissolved, to composite sorbers consisting of hygroscopic inorganic salts dissolved in a polymeric matrix and their use for the removal of HO from the housing of devices sensitive to the presence of HO.
