Patent number: 8309839Abstract: A method of improving the thermoelectric figure of merit (ZT) of a high-efficiency thermoelectric material is disclosed. The method includes the addition of fullerene (C60) clusters between the crystal grains of the material. It has been found that the lattice thermal conductivity (?L) of a thermoelectric material decreases with increasing fullerene concentration, due to enhanced phonon-large defect scattering. The resulting power factor (S2/?) decrease of the material is offset by the lattice thermal conductivity reduction, leading to enhanced ZT values at temperatures of between 350 degrees K and 700 degrees K.Type: GrantFiled: April 30, 2004Date of Patent: November 13, 2012Assignees: GM Global Technology Operations LLC, Shanghai Institute of Ceramics, Chinese Academy of SciencesInventors: Lidong Chen, Xun Shi, Jihui Yang, Gregory P.

Publication number: 20120109503Abstract: The operation of internal combustion, reciprocating engines in some automotive vehicles may be managed such that the engine operation is stopped each time the vehicle is brought to a stop, and then the engine is re-started when the operator presses the accelerator pedal to put the vehicle in motion. In some driving situations the engine of the vehicle may be stopped and re-started many times, which is a mode of engine operation for which the traditional 12 volt, lead-acid battery is not well suited. It is found that a six cell, lithium-ion battery combining LiFePO4 as the active positive electrode material and Li4Ti5O12 as the active negative electrode material, together with suitable separators and a suitable low freezing point electrolyte may be adapted to deliver starting power for repeated engine starting, despite short intervening charging periods.Type: ApplicationFiled: June 28, 2011Publication date: May 3, 2012Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Jihui Yang, Mark W.
