Title
(EN) A SINGLE CELL HYBRID CAPATTERY ENERGY STORAGE SYSTEM
(FR) SYSTÈME DE STOCKAGE D'ÉNERGIE PAR CONDENSATEUR CAPATTERY HYBRIDE À ÉLÉMENT UNIQUE
Abstract
(EN) The present invention envisages a single cell hybrid capattery energy storage system (100) comprising: a battery electrode (101); a bipolar electrode (102); a first separator (104) interposed between the battery electrode (101) and the bipolar electrode (102) forming a battery sub-cell (105); a capacitive carbon electrode (103); and a second separator (106) interposed between the bipolar electrode (102) and the capacitive carbon electrode (103) forming a supercapacitor sub-cell (107). The bipolar electrode (102) acts as an anode for the battery sub-cell (105) which when charged releases electrical energy against the capacitive electrode (103) that absorbs the electrical energy. The battery electrode (101) is a carbon coated battery electrode. The bipolar electrode (102) is made of nanodots of lithium titanium oxide impregnated carbon matrix.
(FR) La présente invention concerne un système de stockage d'énergie par condensateur Capattery hybride à élément unique (100) comprenant : une électrode de batterie (101) ; une électrode bipolaire (102) ; un premier séparateur (104), interposé entre l'électrode de batterie (101) et l'électrode bipolaire (102) formant un sous-élément de batterie (105) ; une électrode capacitive de carbone (103) ; et un second séparateur (106), interposé entre l'électrode bipolaire (102) et l'électrode capacitive de carbone (103) formant un sous-élément de supercondensateur (107). L'électrode bipolaire (102) sert d'anode pour le sous-élément de batterie (105) qui, lorsqu'il est chargé, libère de l'énergie électrique contre l'électrode capacitive (103) qui l'absorbe. L'électrode de batterie (101) est une électrode de batterie revêtue de carbone. L'électrode bipolaire (102) est constituée de nanopoints de matrice de carbone imprégnée d'oxydes de lithium et de titane.
