Lithium-ion electrochemical accumulator with improved leak tightness

The invention relates to a lithium-ion electrochemical accumulator—or Li-ion battery—having improved leak tightness of the liquid electrolyte contained therein. The architecture of the accumulator may be monopolar or bipolar. According to the invention, the sealing of the liquid electrolyte contained in the accumulator is improved through the presence of a leak-tight device or a plurality of leak-tight devices comprising a polymer that, in contact with the liquid electrolyte, converts to a gel in which the electrolyte is trapped and immobilised. Applications: any field in which Li-ion batteries of monopolar or bipolar architecture are likely to be used, and in particular in the manufacture of electric or hybrid vehicles and portable electronic devices (telephones, touchpads, computers, cameras, camcorders, etc).

Electrochemical device

An electrochemical device comprising an electrode assembly in which two types of electrodes are stacked or wound with separators interposed therebetween and an outer container that accommodates the electrode assembly; wherein electrode terminals extend to the outside from within the outer container. The films which cover the electrode assembly overlap each other on the outside of the outer peripheral portion of the electrode assembly, and the outer container is formed by bonding the films to each other. The portion of the films that overlap and are bonded to each other comprises a first sealed portion in which the films overlap and are bonded to each other in an overlapping state with the electrode terminals interposed therebetween, and comprises a second sealed portion in which the films are bonded to each other in a directly overlapping state without interposition of the electrode terminals.

Metal Negative Electrode Cell
