Title (EN) A SOLID STATE BATTERY HAVING A DISORDERED HYDROGENATED CARBON NEGATIVE ELECTRODE
(FR) ACCUMULATEUR SOLIDE A ELECTRODE NEGATIVE DE CARBONE HYDROGENE DESORDONNEE
Abstract:
(EN) A solid state battery comprising a substrate (1) at least one multilayered electrochemical cell deposited onto the substrate (1); each multilayered electrochemical cell comprising: a layer of disordered hydrogenated carbon material negative electrode material (3) capable of electrochemically adsorbing and desorbing lithium ions or both lithium and hydrogen ions during charge and discharge; a layer of positive electrode material (5) capable of electrochemically desorbing and adsorbing lithium ions or both lithium and hydrogen ions during charge and discharge; and a layer of insulating/conducting material (4) disposed between the layer of positive electrode material (5) and the layer of negative electrode material (3), where the layer of insulating/conducting material (4) is electrically insulating and capable of readily conducting or transporting lithium ions or both lithium and hydrogen ions from the layer of positive electrode material (5) to the layer of the layer of negative electrode material (3) while the battery is charging and from the layer of negative electrode material (3) to the layer of positive electrode material (5) while the battery is discharging; and an electrically conductive layer (6) deposited atop the last of the at least one multilayered electrochemical cells, the electrically conductive layer (6) providing one battery terminal.
(FR) Accumulateur solide comprenant un substrat (1) et au moins une cellule électrochimique multicouches déposée sur le substrat (1), chaque cellule électrochimique multicouches comprenant: une couche de matériau formant électrode négative (3) constituée de carbone hydrogéné désordonné capable d'adsorber et désorber électrochimiquement des ions lithium ou à la fois des ions lithium et hydrogène au cours de la charge et de la décharge; une couche de matériau formant électrode positive (5) capable de désorber et d'adsorber électrochimiquement les ions lithium ou à la fois les ions lithium et hydrogène au cours de la charge et de la décharge; et une couche de matériau isolant/conducteur (4) disposée entre la couche de matériau formant électrode positive (5) et la couche de matériau formant électrode négative (3); la couche de matériau isolant/conducteur (4) est électriquement isolante et capable de conduire ou de transporter des ions lithium, ou à la fois des ions lithium et des ions hydrogène depuis la couche de matériau formant électrode positive (5) vers la couche de matériau formant électrode négative (3) lorsque la batterie se charge et depuis la couche de matériau formant électrode négative (3) vers la couche de matériau formant électrode positive (5) lorsque la batterie se décharge; et une couche conductrice électriquement (6) déposée par-dessus la dernière des cellules électrochimiques multicouches, au moins au nombre de une, la couche électriquement conductrice (6) constituant une borne de la batterie.
