Publication number: 20130130125Abstract: A cross-linked microporous polymeric battery electrode separator membrane is described. Such membranes, which would otherwise be soluble above a particular, generally high temperature in selected battery electrolyte systems, once at least in part cross-linked, swell in the electrolyte at the particular higher temperature instead of dissolving. When the membrane separators are restrained between solid electrodes in a battery, the separator cannot increase in bulk volume, and the swelling occurs within the pores with the pore volume decreasing from its original bulk volume. The drop in pore volume causes the battery current density to drop, thereby reducing the heat generation within the hot area of the battery. This process provides a measure of safety against overheating and fires, and the battery is capable of continued usage if the overheating is localized.Type: ApplicationFiled: May 16, 2012Publication date: May 23, 2013Inventor: Ray L.

Publication number: 20120258241Abstract: The feasibility of adding glass to conventional SOFC cathode contact materials in order to improve bonding to adjacent materials in the cell stack is assessed. A variety of candidate glass compositions were added to LSM and SSC. The important properties of the resulting composites, including conductivity, sintering behavior, CTE, and adhesion to LSCF and MCO-coated 441 stainless steel were used as screening parameters. The most promising CCM/glass composites were coated onto MCO-coated 441 stainless steel substrates and subjected to ASR testing at 800° C. In all cases, ASR is found to be acceptable. Indeed, addition of glass is found to improve bonding of the CCM layer without sacrificing acceptable conductivity.Type: ApplicationFiled: April 5, 2012Publication date: October 11, 2012Applicant: The Regents of the University of CaliforniaInventors: Michael C.
