Abstract

A method for producing a secondary lithium cell which has at least one lithium-cycling negative electrode, at least one lithium-intercalating positive electrode, at least one separator disposed between the positive and the negative electrode, and a nonaqueous lithium ion-conducting electrolyte. The method is carried out by the electrodes and/or the separator being coated, by means of electrostatic powder coating, with wax particles which are insoluble in the electrolyte and have a melting temperature of from about 50 to about 150 .degree. C. and a mean particle size of from about 6 to about 20 .mu.m, the amount of wax being between about 0.5 and about 2.5 mg/cm.sup.2 of electrode area.

Methods for using atomic layer deposition to produce a film for solid state electrolytes and protective electrode coatings for lithium batteries

Patent Elam, Jeffrey W.; Meng, Xiangbo

A method for using atomic layer deposition to produce a film configured for use in an anode, cathode, or solid state electrolyte of a lithium-ion battery or a lithium-sulfur battery. The method includes repeating a cycle for a predetermined number of times in an inert atmosphere. The cycle includes exposing a substrate to a first precursor, purging the substrate with inert gas, exposing the substrate to a second precursor, and purging the substrate with inert gas. The film is a metal sulfide.

Chemical overcharge protection of lithium and lithium-ion secondary batteries

Patent Abraham, Kuzhikalail M [Needham, MA]; Rohan, James F [Cork City, IE]; Foo, Conrad C [Dedham, MA]; ...

This invention features the use of redox reagents, dissolved in non-aqueous electrolytes, to provide overcharge protection for cells having lithium metal or lithium-ion negative electrodes (anodes). In particular, the invention features the use of a class of compounds consisting of thianthrene and its derivatives as redox shuttle reagents to provide overcharge protection. Specific examples of this invention are thianthrene and 2,7-diacetyl thianthrene. One example of a rechargeable battery in which 2,7-diacetyl thianthrene is used has carbon negative electrode (anode) and spinet LiMn.sub.2 O.sub.4 positive electrode (cathode).

Detergent composition comprising a cellulase containing cell-free fermentate produced from microorganism ATCC 55702 or mutant thereof

Patent Dees, H Craig [Lenoir City, TN]

Bacteria which produce large amounts of a cellulase-containing cell-free fermentate have been identified. The original bacterium (ATCC 55703) was genetically altered using nitrosoguanidine (MNNG) treatment to produce the enhanced cellulase producing bacterium (ATCC 55702), which was identified through replicate plating. ATCC 55702 has improved characteristics and qualities for the degradation of cellulosic waste materials for fuel production, food processing, textile processing, and other industrial applications. ATCC 55702 is an improved bacterial host for genetic manipulations using recombinant DNA techniques, and is less likely to destroy genetic manipulations using standard mutagenesis techniques.
