摘要： Solid electrolytes have a favorable combination of properties such as high conductivity, high transference number, optimum processability, and low brittleness. A composite electrolyte includes some amount of a class of network polymer electrolytes with high transference number and high room temperature conductivity, and an additional polymeric component to contribute mechanical integrity and/or processability. The solid electrolytes can include a network polymer having linked nodes composed of a tetrahedral arylborate composition and a linear polymer combined with the network polymer as a composite. The solid electrolytes can be used in thin films and in solid-state batteries.

摘要： Polymer-based electrolyte materials that may be used as proton exchange membranes in proton exchange membrane fuel cells are described. The disclosed polymer electrolyte materials can be generally defined by a general 1,3-dicarbonyl repeat unit that may include various side chain and main chain constituents changing the acidity of the C—H proton(s) located between the carbonyl groups. Accordingly, by varying such side-chain and main-chain constituents, the proton-conduction properties the disclosed proton exchange membranes can be manipulated, and methods of producing the same. Methods of producing such polymer electrolyte materials are also disclosed.

摘要： An electrode configuration for a battery cell includes a positive electrode, a negative electrode, a separator interposed between the positive electrode and the negative electrode, and a low counter-ion permeability layer interposed between the separator and the positive electrode. The separator has a first permeability to counter-ions, which do not participate in the battery electrode reactions, and the low counter-ion permeability layer has a second permeability to the counter-ions that is less than the first permeability. The separator includes a first salt concentration adjacent to the low counter-ion permeability layer and a second salt concentration adjacent to the negative electrode, and the second salt concentration is greater than the first salt concentration.
