RECHARGEABLE LITHIUM BATTERIES COMPRISING MEANS FOR THE SORPTION OF HARMFUL SUBSTANCES IN THE FORM OF A MULTILAYER POLYMERIC SHEET |
摘要 |
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 (10) comprised of an inner layer (12) of a polymeric material containing particles (11) of one or more getter materials for the sorption of the harmful substances, and at least one external protective layer (13) of a polymeric material impermeable to the electrolyte, wherein all the polymeric materials are permeable to the harmful substances. |
