Title
(EN) IN SITU FORMATION OF SOLID-STATE POLYMER ELECTROLYTES FOR BATTERIES
(FR) FORMATION IN SITU D'ÉLECTROLYTES POLYMÈRES MONOLITHIQUES POUR BATTERIES
Abstract
(EN)
Provided are compositions including one or more cyclic ether(s), one or more salt(s), which may be one or more lithium salt(s), one or more sodium salt(s), or a combination thereof, and, optionally, one or more ring-opening polymerization initiator(s). The compositions may be used to form solid-state electrolytes. Also provided are methods for forming solid-state electrolytes using the compositions and devices comprising one or more composition(s) or one or more solid-state electrolyte(s) using the compositions.
(FR)
L'invention concerne des compositions comprenant un ou plusieurs éthers cycliques, un ou plusieurs sels, qui peuvent être un ou plusieurs sels de lithium, un ou plusieurs sels de sodium, ou une combinaison de ces derniers, et, éventuellement, un ou plusieurs initiateurs de polymérisation par ouverture de cycle. Les compositions peuvent être utilisées pour former des électrolytes monolithiques. L'invention concerne également des procédés de formation d'électrolytes monolithiques à l'aide des compositions et de dispositifs comprenant une ou plusieurs compositions ou un ou plusieurs électrolytes monolithiques à l'aide des compositions.
