Title
(EN) LITHIUM METAL ANODE COATING
(FR) REVÊTEMENT D'ANODE AU LITHIUM MÉTALLIQUE
Abstract
(EN) The invention pertains to a composition for coating a lithium metal anode of a lithium metal battery comprising a mixture of nanoparticles of at least one electrolyte-insoluble lithium salt and at least one lithium ion-coordinating polymer, as well as to corresponding uses and methods. The present invention further encompasses a lithium metal anode coated with the inventive composition as well as a battery comprising the coated lithium metal anode.
(FR) L'invention concerne une composition pour le revêtement d'une anode au lithium métallique d'une batterie au lithium métallique comprenant un mélange de nanoparticules d'au moins un sel de lithium insoluble dans l'électrolyte et d'au moins un polymère de coordination d'ions lithium, ainsi que des utilisations et des procédés correspondants. La présente invention concerne en outre une anode au lithium métallique revêtue de la composition de l'invention ainsi qu'une batterie comprenant l'anode au lithium métallique revêtue.
