Bellcore system

GORE. The CORE Electronic Chemistry Library is a joint project of Cornell University, OCLC (On-line Computer Library Center), Bell Communications Research (Bellcore), and the American Chemical Society. The CORE database will contain the full text of American Chemical Society Journals from 1980, associated information from Chemical Abstracts Service, and selected reference texts. It will provide machine-readable text that can be searched and displayed, graphical representations of equations and figures, and full-page document images. The project will examine the performance obtained by the use of a traditional printed index as compared with a hypertext system (SUPERBOOK) and a document retrieval system (Pixlook) (6,116). 

Solvated polymers are approaching "gels" in properties, depending on the mobility of the molecules. In some cases the action of a binder and of a separator are combined. By extraction of one of the components and refilling the voids with a liquid, a two-phase system can be created (Bellcore). There are irreversible and re-... 

The PVdF—HFP separators used in PLION cells were around 3 mil thick, and had poor mechanical properties. It has been reported that the major source of rate limitation in PLION cells was the separator thickness. The rate capability of these cells can be significantly improved by decreasing the separator thickness to that typically used in liquid electrolyte system. Moreover, in the absence of shutdown function. the separator does not contribute to cell safety in any way. Park et al. reported that the HFP content in separators did not have any significant impact on cell performance. The Bellcore process has proven to be an elegant laboratory process but is difficult to implement in large-scale production. 

The report had a catalyzing effect. What had been a ho-hum field of research was now the scene of frenzied worldwide competition as the hunt for higher-temperature superconductors was on once again. Only this time the search had a narrower focus, the oxides. Among the first to jump into the race was Bell Communications Research (Bellcore), which provides research and technical support for the telephone companies formed in the breakup of the Bell System.

The test methods used to evaluate the corrosion of materials and plant components are described in Bellcore Technical Advisories (TAs), Technical References (TRs), and Generic Requirements (GRs). Many of the tests in these documents include and reference ASTM, UL, ANSI/NEMA, and MIL standards. Some of the test methods are specific to the telecommunication industry and can be found only in TAs, TRs, and GR s. Manufacturing and purchase of telecommunication plant components are based on these documents, thus, available to the manufacturers and to companies that sell them. The methods used for in-plant testing are described in Bell System Practices (BSPs) and licensed Bellcore documents. ...

Valence Technology are now advancing toward commercializing a lithium rechargeable battery based on the Bellcore technology, although other efforts have focused on a new gelled system [125-127]. This electrolyte is a radiation-cross-linked polymer formed from a mixture of Hquid prepolymer compounds, typically PEO-based acrylates, which have crossHnkable unsaturated centers, a... 

Motorola, Polystor, Danionics, Philips and Sony have developed several other polymer-based LiPB systems. These are in various stages of commercial development but little is known about the production details. PolyStor [17,18] has initiated commercial production under a license for the Motorola technology. It uses a PVdF binder but eliminates the extraction step of the Bellcore process. This process can be adapted for the wound constructions as well as for the stacked flat plate constructions. Another technology has...
