BASF et Argonne ont mis un terme à la procédure en cours contre Umicore auprès de la United States District Court for the District of Delaware. The teams new structure for the cathodes micro-sized particles could lead to longer-lasting and safer batteries. BASF and Argonne, according to Judge Pender, established persuasively that Umicore’s NMC infringes. The transient kinetic technique of Temporal Analysis of Products (TAP), density functional theory, and infrared spectroscopy have been used to study the formation of surface impurities on varying nickel content NMC materials (NMC811. Tags A123 Systems NMC technology Argonne National Laboratory Lithium ion. Surface impurities involving parasitic reactions and gas evolution contribute to the degradation of high Ni content LiNi x Mn y Co z O 2 (NMC) cathode materials. An initial NCM523 electrode using the experimental binder was made on the CAMP Facility’s pilot scale coater for scoping purposes. This new binder system was readily adapted to continuous roll-to-roll coating by Argonne. Umicore détient maintenant une licence en vue de fabriquer, utiliser, vendre, proposer à la vente, distribuer et importer aux Etats-Unis les matériaux cathodiques nickel manganèse cobalt (NMC) destinés aux batteries lithium ion sous les brevets américains détenus par BASF et Argonne et portant les n° 6.677.082 6.680.143 7.135.252 et 7.468.223. Argonne researchers have made another breakthrough with the NMC cathode. NMC 811 is meant to be the next-generation cathode - better and cheaper. Argonne’s CAMP Facility on their pilot-scale coater using commercial un-modified NCM523 powder. Umicore est arrivé à une résolution d’affaires concernant l’affaire des brevets en cours avec BASF et Argonne National Laboratory. 25 avril 2017 - Umicore a conclu un accord avec BASF et Argonne relatif à la plainte pour violation des brevets NMC.
