Abstract
Crosslinked elastomeric electrolytes and compatible separator materials are provided for use in electrical energy storage devices such as aluminum electrolytic capacitors and batteries. The separator material is impregnated with the electrolyte, and as a result, the electrolyte acts to strengthen the separator material, allowing a storage device to be constructed with separator materials of reduced thickness and thereby achieving an improvement in the energy density of the storage device. Methods of making such electrolytes and storage devices are also disclosed.
