摘要:
The electrolyte includes one or more salts and a silane. The silane has a silicon linked to one or more first substituents that each include a poly(alkylene oxide) moiety or a cyclic carbonate moiety. The silane can be linked to four of the first substituents. Alternately, the silane can be linked to the one or more first substituents and one or more second substituents that each exclude both a poly(alkylene oxide) moiety and a cyclic carbonate moiety.
摘要:
Fast-cure gel polymer electrolytes are prepared by trapping an oligo(alkylene glycol)siloxane or silane in a three dimensional polymer matrix. An ion-conducting phase of the electrolyte contains a siloxane or silane compound and a lithium salt. Such siloxanes or silanes include a silicon or silicon oxide group having four or less substituents that is an oligo(alkylene glycol), or cyclic carbonate moiety.
摘要:
A process includes contacting a carbon support material with an oxidizing agent followed by the acid treatment to form a functionalized carbon support material including surface hydroxyl functionality; contacting the functionalized carbon support material with a solution of a catalyst precursor; and adjusting the pH of the solution to produce a carbon supported catalyst material including a metal oxide catalyst.
