Title (EN) METHOD OF PRE-DOPING A LITHIUM ION CAPACITOR
(FR) PROCÉDÉ DE PRÉ-DOPAGE D'UN CONDENSATEUR AU LITHIUM-ION
Abstract:
(EN) A method for pre-doping a lithium ion capacitor, including: compressing a lithium ion capacitor of the formula: C/S/A/S/C/S/A/S/C, where: /A/ is an anode coated on both sides with an anode carbon layer, and each anode carbon layer is further coated with lithium composite powder (LCP) layer; C/ is a cathode coated on one side with a layer of an cathode carbon mixture; and S is a separator; and a non-aqueous electrolyte; and conditioning the resulting compressed lithium ion capacitor, for example, at a rate of from C/20 to 4C, and the conditioning redistributes the impregnated lithium as lithium ions in the anode carbon structure. Also disclosed is a carbon coated anode having an LCP layer compressed on the carbon coated anode.
(FR) L'invention concerne un procédé de pré-dopage d'un condensateur au lithium-ion, consistant à : comprimer un condensateur au lithium-ion de la formule : C/S/A/S/C/S/A/S/C, où : /A/ est une anode revêtue sur les deux côtés avec une couche de carbone d'anode, et chaque couche de carbone d'anode est en outre revêtue avec une couche de poudre composite de lithium (LCP) ; C/ est une cathode revêtue sur un côté avec une couche d'un mélange de carbone de cathode ; et S est un séparateur ; et un électrolyte non aqueux ; et conditionner le condensateur au lithium-ion comprimé résultant, par exemple, à un taux de C/20 à 4C, et le conditionnement redistribue le lithium imprégné en tant qu'ions lithium dans la structure de carbone d'anode. L'invention concerne également une anode revêtue de carbone ayant une couche de LCP comprimée sur l'anode revêtue de carbone.
