Abstract
Official abstract text for this publication.
An ionogel is formed by mixture of precursors, a catalyst, and an ionic liquid to form a sol-gel. The precursors and the catalyst react to form a solid-phase matrix that includes pores, wherein the ionic liquid is disposed within the pores. The gel is dried by way of thermal or vacuum drying to remove liquid byproducts of the precursor-catalyst reaction and to form a solid-state ionogel that comprises the solid-phase matrix with the ionic liquid disposed therein. The ionogel is immersed in a quantity of a liquid electrolyte that is soluble in the ionic liquid. As the liquid electrolyte dissolves into the ionic liquid, the ionic liquid is displaced by the liquid electrolyte, yielding an ionogel having the liquid electrolyte disposed within its pores.
First claim
Opening claim text (preview).
What is claimed is: 1. A battery, comprising: a first electrode configured to accept lithium ions; a second electrode configured to accept lithium ions; and an ionogel disposed between the first electrode and the second electrode, wherein a first liquid was used to form the ionogel, and further where the ionogel comprises: a solid-phase matrix having pores formed therein; and a second liquid disposed within the pores of the solid-phase matrix, the second liquid comprising a lithium-based electrolyte in solution with at least one of 1,3 dioxolane (DOL), or dimethyl ether (DME), where the second liquid displaced the first liquid that was used to form the ionogel. 2. The battery of claim 1 , wherein the first electrode comprises at least one of LiFePO 4 (LFP), lithium titanate (LTO), conductive carbon, polyvinylidene fluoride (PVDF), or n-methyl-2-pyrrolidone (NMP). 3. The battery of claim 1 , wherein the lithium-based electrolyte comprises lithium bis(fluoromethanesulfonyl)imide. 4. The battery of claim 1 , wherein the solid-phase matrix comprises at least one of tetraethylorthosilicate (TEOS) and triethylvinylorthosilicate (VTEOS). 5. The battery of claim 1 , wherein the solid-phase matrix comprises poly(vinylidene fluoride-co-hexafluoropropylene).
