Title (EN) NANO-POROUS BNNT COMPOSITE WITH THERMAL SWITCHING FOR ADVANCED BATTERIES
(FR) COMPOSITE DE BNNT NANOPOREUX À COMMUTATION THERMIQUE POUR ACCUMULATEURS AVANCÉS
Abstract:
(EN) Thermoresponsive composite switch (TRCS) membranes for ion batteries include a porous scaffolding providing ion channels and a thermoresponsive polymer coating. Boron nitride nanotube (BNNT)/polymer composite TRCS membrane embodiments are preferable due to unique BNNT properties. A BNNT scaffold coated with one or more polymers may form a composite separator with tunable porosity (porosity level and pore size distribution), composition, wettability, and superior electronic isolation, oxidative/reduction resistance, and mechanical strength. The BNNT/polymer composite TRCS membrane optimizes the performance of ion batteries with tunable separator thicknesses that may be under 5μιη. Nano- scale porosity with thin separator thicknesses improves the charge density of the battery. Nano- scale architecture allows for reversible localized switching on the nano scale, in proximity to thermally stressed ion substrates. Polymer thermal expansion will decrease porosity at temperatures approaching the thermal runaway point. The BNNT polymers composite therefore functions as a TRCS.
(FR) L'invention porte sur des membranes à commutateur composite thermosensible (TRCS) pour accumulateurs ioniques, qui comprennent un échafaudage poreux fournissant des canaux ioniques et un revêtement polymère thermosensible. Des modes de réalisation de membranes TRCS en composite nanotubes de nitrure de bore (BNNT)/polymère sont préférables en raison des propriétés uniques des BNNT. Un échafaudage de BNNT enrobé d'un ou plusieurs polymères peut former un séparateur composite à porosité (niveau de porosité et distribution de tailles de pores), composition et mouillabilité réglables, et à isolation électronique, résistance à l'oxydation/réduction et résistance mécanique supérieures. La membrane TRCS en composite BNNT/polymère optimise les performances d'accumulateurs ioniques ayant des épaisseurs de séparateur réglables qui peuvent être inférieures à 5 μm. Une porosité nanométrique avec de minces épaisseurs de séparateur améliore la densité de charge de l'accumulateur. L'architecture nanométrique permet une commutation réversible localisée à l'échelle nanométrique, à proximité de substrats soumis à des contraintes thermiques. La dilatation thermique du polymère réduira la porosité à des températures s'approchant du point d'emballement thermique. Le composite BNNT/polymère fonctionne donc comme un TRCS.
