Methods and formulations for modified silicone resins of Formula (I) are presented: The R, R, and Rare each independently selected from a group consisting of H, alkyl, alkenyl, alkynyl, and aryl; n ranges from 1 to 10; m ranges from 1 to 200; and p ranges from 2 to 1,000. The elastomeric materials prepared from modified silicone resins display robust mechanical properties following prolonged exposure to high temperatures (e.g., 316&#xb0; C. or higher).

Temperature-resistant silicone resins

Methods and formulations for modified silicone resins of Formula (II) are presented. Formula (II) comprises at least one of each of the following subunits: The R, R, R, R, R, R, R, R, R, Rand Rare each independently selected from a group consisting of H, alkyl, alkenyl, alkynyl, and aryl. The X is selected from a group consisting of arylene, transition metal, inorganic oxide, and silsesquioxane. The values of t ranges from 1 to 10, y ranges from 1 to 200 and z ranges from 1 to 1,000. The elastomeric materials prepared from modified silicone resins display robust mechanical properties following prolonged exposure to high temperatures (e.g., 316&#xb0; C. or higher).

This invention, in some variations, provides a separator for a lithium-sulfur battery, comprising a porous substrate that is permeable to lithium ions; and a lithium-ion-conducting metal oxide layer on the substrate, wherein the metal oxide layer includes deposits of sulfur that are intentionally introduced prior to battery operation. The deposits of sulfur may be derived from treatment of the metal oxide layer with one or more sulfur-containing precursors (e.g., lithium polysulfides) prior to operation of the lithium-sulfur battery. Other variations provide a method of charging a lithium-sulfur battery that includes the disclosed separator, the charging being accomplished by continuously applying a substantially constant voltage to the lithium-sulfur battery until the battery charging current is at or below a selected current.

Both the reaction of hydride-forming compositions with hydrogen to form hydrides, and the decomposition of such hydrides to release hydrogen may be promoted electrochemically. These reactions may be conducted reversibly, and if performed in a suitable cell, the cell will serve as a hydrogen storage and release device.

A method of coating a surface of a fuel cell plate is disclosed herein, and involves forming a sol gel mixture by mixing a weak acid and a composition including at least two metal oxide precursors. One of the metal oxide precursors is configured to be hydrolyzed by the weak acid to form a mixed metal oxide framework with an other of the metal oxide precursors having at least one organic functional group that is not hydrolyzed by the weak acid. The mixture is applied to the surface, and is condensed by exposure to air at least one predetermined temperature and for a predetermined time. The sol gel mixture is immersed in water at a predetermined temperature and for a predetermined time to form a porous, hydrophilic, and conductive film on the surface.

This invention provides a battery, such as a lithium-ion battery, that includes an encapsulated fire-retardant material. In some embodiments, stable polymer spheres are used to encapsulate an effective fire-retardant material. Under normal operating conditions, the fire-retardant material does not contact the electrolyte, cathode, or anode, thus minimizing performance reduction that occurs when fire-retardant materials are in the direct presence of the electrolyte. Under thermal runaway or excessive temperatures, the fire retardant material vaporizes through the melted encapsulating phase, thereby releasing fire-retardant material to minimize or prevent flammability in the battery.
