20110189548 | IONIC ADDITIVES FOR ELECTROCHEMICAL DEVICES USING INTERCALATION ELECTRODES - An electrochemical cell comprising a cathode comprising an electrode active material that reversibly intercalates and de-intercalates any of cations and molecules; an anode comprising an electrode active material that reversibly intercalates and de-intercalates any of cations, anions, and molecules; a separator material that separates the cathode from the anode; and an electrolyte comprising a base electrolyte composition, an ionic compound additive, and a solvent comprising any of aqueous and non-aqueous electrolyte solvents, wherein the additive dissolves in the base electrolyte composition as well a majority of the aqueous or non-aqueous electrolyte solvents, wherein the additive comprises a solubility of at least approximately 0.01 in the base electrolyte composition, wherein the additive dissociates into corresponding cations and anions upon dissolution, and wherein the cations originate from a metal element and reduce to an elemental form at a potential that is at least approximately 0.50 V above that of lithium. | 08-04-2011 |
20090292130 | BIBENZOTHIOPHENE DERIVATIVES - Compounds containing bibenzochalcogenophene structures are provided in which the chalcogenide is sulfur, selenium, or tellurium. The compounds are characterized by planarity, rigid conjugation structure and high charge mobility making them useful as organic semiconductor in optical devices, electronic devices and integrated devices like organic field effect transistors (OFET) for thin film transistor liquid crystal display (LCD), electrophoretic display such as electronic paper, organic light emitting diode (OLED) for flat panel displays, organic radio frequency identification (ORFID) tags, organic photovoltaic (OPV), sensor devices, and analog and digital electronics. | 11-26-2009 |
