Abstract
(EN)
This disclosure provides a lithium (Li) ion battery that includes an anode, a cathode positioned opposite to the anode, a porous separator positioned between the anode and the cathode, and a liquid electrolyte in contact with the anode and the cathode. The anode includes an electrically conductive substrate. A first film is deposited on the electrically conductive substrate. The first film includes a first concentration of carbon particles in contact with each other and defines a first electrical conductivity for the first film. Each of the carbon particles includes a plurality of aggregates formed of few layer graphene sheets. The plurality of aggregates form a porous structure configured to undergo a lithiation, which can include any one or more of an intercalation operation or a plating operation. The anode and the cathode can include an electroactive material. The porous structure can provide conduction between the few layer graphene sheets.

La présente divulgation concerne une batterie au lithium (Li) ion qui comprend une anode, une cathode positionnée à l'opposé de l'anode, un séparateur poreux positionné entre l'anode et la cathode, et un électrolyte liquide en contact avec l'anode et la cathode. L'anode comprend un substrat électroconducteur. Un premier film est déposé sur le substrat électroconducteur. Le premier film comprend une première concentration de particules de carbone en contact l'une avec l'autre et définit une première conductivité électrique du premier film. Chacune des particules de carbone comprend une pluralité d'agrégats formés de quelques feuilles de graphène en couches. La pluralité d'agrégats forment une structure poreuse configurée pour subir une lithiation, qui peut comprendre l'une quelconque ou plusieurs opérations parmi une opération d'intercalation ou une opération de placage. L'anode et la cathode peuvent comprendre un matériau électroactif. La structure poreuse peut assurer une conduction entre les quelques feuilles de graphène de couche.
