Title
(EN) MOISTURE ELECTRIC GENERATOR BATTERY CELL
(FR) CELLULE DE BATTERIE DE GÉNÉRATEUR ÉLECTRIQUE À HUMIDITÉ
Abstract
(EN) A functional layer for a moisture electric generating battery cell wherein the functional layer includes graphene oxide having a ratio of C=O bonds to C-C bonds of more than 1 :9. The functional layer include treated graphene oxide having an interlayer spacing that is greater than the interlayer spacing of graphene oxide from which the treated graphene oxide is prepared. The functional layer consists of graphene oxide and a polymer binder that is selected to bond with an electrically conductive substrate. The polymer binder may be one or more of: PVA, PVB, PMMA or PVP. The graphene oxide and polymer binder are treated with acid such as HC1, H2SO4 or HNO3. The electrically conductive substrate forming an electrode may be mounted onto a further substrate, for use as a moist-electric generation (MEG) in an electronic device. The electronic device is configured to have a surface positioned in contact with the skin of a subject when in use.
(FR) L'invention concerne une couche fonctionnelle pour une cellule de batterie à génération d'électricité par humidité, ladite couche fonctionnelle contenant de l'oxyde de graphène ayant un rapport liaisons C=O - liaisons C-C supérieur à 1 : 9. La couche fonctionnelle contient de l'oxyde de graphène traité présentant un espacement intercouche supérieur à l'espacement intercouche de l'oxyde de graphène à partir duquel l'oxyde de graphène traité est préparé. La couche fonctionnelle est constituée d'oxyde de graphène et d'un liant polymère sélectionné pour se lier à un substrat électroconducteur. Le liant polymère peut être au moins un des éléments suivants : PVA, PVB, PMMA ou PVP. L'oxyde de graphène et le liant polymère sont traités avec de l'acide tel que HC1, H2SO4 ou HNO3. Le substrat électroconducteur formant une électrode peut être monté sur un autre substrat, pour servir de générateur électrique à humidité (MEG) dans un dispositif électronique. Le dispositif électronique est configuré pour comporter une surface positionnée en contact avec la peau d'un individu lors de l'utilisation.
