ABSTRACT:
An electrochemical energy storage device is described. The electrochemical energy storage device includes: (1) a polymer electrode having (A) an organic conjugated compound; and (B) an ionically conductive polymer electrolyte, wherein the organic conjugated compound and the ionically conductive polymer electrolyte form a bicontinuous interpenetrating network, in which the organic conjugated compound and the ionically conductive polymer electrolyte form distinct continuous phases and an average phase size of the organic conjugated compound in the bicontinuous interpenetrating network is in the order of nanometers; and (2) a separator that is electronically non-conductive and contacts the polymer electrode such that the separator facilitates the transport of ions to and from the polymer electrode. Another electrochemical energy storage device is also described. This electrochemical energy storage device includes a surfactant in the polymer electrode to form a bicontinuous interpenetrating network of nanometer scale phase size. Yet another electrochemical energy storage device is also described. This electrochemical energy storage device includes a conjugated compound having a side-chain that has an affinity to a polymer electrolyte and as a result, the conjugated compound and polymer electrolyte form a more compact bicontinuous interpenetrating network.
