Abstract
(EN)
This electrode production method produces an electrode which is provided with an active material layer containing an active material that is doped with an alkali metal. In an atmosphere having an oxygen concentration of from 1% by volume to 18% by volume (inclusive), the active material is doped with an alkali metal with use of a dope solution that contains ions of the alkali metal. In a method for producing an electricity storage device according to the present invention, a negative electrode active material contained in a negative electrode active material layer of a negative electrode is doped with an alkali metal with use of a dope solution that contains ions of the alkali metal in an atmosphere having an oxygen concentration of from 1% by volume to 18% by volume (inclusive). After the doping of the alkali metal, the electrode cell is formed by sequentially stacking the negative electrode, a separator, and an electrode that is different from the negative electrode.

L'invention porte sur un procédé de production d'électrode permettant de produire une électrode pourvue d'une couche de matériau actif contenant un matériau actif qui est dopé avec un métal alcalin. Dans une atmosphère présentant une concentration en oxygène allant de 1 % en volume à 18 % en volume (inclus), le matériau actif est dopé avec un métal alcalin à l'aide d'une solution de dopage qui contient des ions du métal alcalin. Dans un procédé de production d'un dispositif de stockage d'électricité selon la présente invention, un matériau actif d'électrode négative contenu dans une couche de matériau actif d'électrode négative d'une électrode négative est dopé avec un métal alcalin à l'aide d'une solution de dopage qui contient des ions du métal alcalin dans une atmosphère présentant une concentration en oxygène allant de 1 % en volume à 18 % en volume (inclus). Après le dopage du métal alcalin, la cellule d'électrode est formée par empilement séquentiel de l'électrode négative, d'un séparateur et d'une électrode qui est différente de l'électrode négative.
