Abstract
An electrochemical device includes a first electrode in electrical communication with a first current collector, a second electrode in electrical communication with a second current collector and a crosslinked solid polymer in contact with the first and second electrodes. At least one of the first and second electrodes includes a network of electrically connected particles comprising an electroactive material, and the particles of one electrode exert a repelling force on the other electrode when the first and second electrodes are combined with an uncrosslinked precursor to the solid polymer.
Claims16
A composition for use in the formation of an electronic device, comprising:
- a mixture of a liquid polymer precursor that is crosslinkable to form a solid polymer;
- at least one component of a first electrode;
- and
- at least one component of a second electrode, wherein the components of the first and second electrodes are selected to exert a repelling force on each other when combined with the polymer precursor;
- and
- wherein the first electrode has a refractive index n1, the second electrode has a refractive index n3, the liquid polymer precursor has a refractive index n2, and n1<n2<n3.
