Title:
LITHIUM ELECTROCHEMICAL GENERATOR COMPRISING AT LEAST A BIPOLAR ELECTRODE WITH CONDUCTIVE ALUMINIUM OR ALUMINIUM ALLOY SUBSTRATES
Document Type and Number:
WIPO Patent Application WO2003047021
Kind Code:
A3
Abstract:
The invention concerns a lithium electrochemical generator comprising two peripheral electrodes, one positive and the other negative, including each an electrical conductive substrate (13, 21) and an active layer (14, 20) containing an active material, at least a bipolar electrode including a positive active layer (18) on a first electrical conductive substrate and a negative active layer (16) on a second electrical conductive substrate, said substrates being attached and two separators (15, 19) enclosing each bipolar electrode, wherein the electrical conductive substrates of each bipolar electrode are made of identical or different materials selected among aluminium and its alloys and the negative active material of the bipolar electrode inhibits formation of aluminium alloy with the electrical conductive substrates in operating conditions of the storage cell.
