Title: Excited state management

Abstract

Arrangements and techniques for providing organic emissive layers are provided, in which the emissive layer includes a first dopant having a dissociative energy level. A second dopant in the emissive layer provides a solid state sink energy level, to which doubly excited excitons and/or polarons may transition instead of to the dissociative energy level, thereby decreasing the undesirable effects of transitions to the dissociative energy level.

Thermal management system and method for a solid-state energy storing device

Patent Rouillard, Roger [Beloeil, CA]; Domroese, Michael K [South St. Paul, MN]; Gauthier, Michel [La Prairie, CA]; ...

An improved electrochemical energy storing device includes a number of thin-film electrochemical cells which are maintained in a state of compression through use of an internal or an external pressure apparatus. A thermal conductor, which is connected to at least one of the positive or negative contacts of each electrochemical cell, conducts current into and out of the electrochemical cells and also conducts thermal energy between the electrochemical cells and thermally conductive material disposed on a wall structure adjacent the conductors. The wall structure includes electrically resistive material, such as an anodized coating or a thin film of plastic. Themore » « less

Management of gas pressure and electrode state of charge in alkaline batteries

Patent Turney, Damon; Ito, Yasumasa; Banerjee, Sanjoy

An inventive, new system that measures gas composition and pressure in the headspace of an aqueous electrolyte battery is described. The system includes a microcontroller that can use the composition and pressure information to connect a third electrode to either the anode(s) or the cathode(s) in order to balance the state of charge between the two. Results have shown that such a system can control the gas pressure inside a sealed flooded aqueous electrolyte battery to remain below 20 kPa (3 psi) and greatly extend the useable life of the battery.
