Title (EN) ANODE MATERIALS FOR LITHIUM ION BATTERIES AND METHODS OF MAKING AND USING SAME
(FR) MATÉRIAUX D'ANODE DESTINÉS À DES BATTERIES AU LITHIUM-ION ET PROCÉDÉS DE FABRICATION ET D'UTILISATION ASSOCIÉS
Abstract:
(EN) An electrochemically active material includes an active phase that includes silicon, and at least one inactive phase having a Scherrer Grain Size of greater than 5 nanometers. Each inactive phase of the material having a Scherrer Grain Size of greater than 5 nanometers has a lattice mismatch to Li 15Si4 of greater than 5%.
(FR) Un matériau électrochimiquement actif comprend une phase active qui comprend du silicium, et au moins une phase inactive présentant une granulométrie Scherrer supérieure à 5 nanomètres. Chaque phase inactive du matériau présentant une granulométrie Scherrer supérieure à 5 nanomètres présente un désaccord de réseau par rapport à Li 15Si4 qui est supérieur à 5%.
