  • Patent number: 9705159
    Abstract: A nonaqueous electrolyte secondary battery includes: a positive electrode 4 including a positive electrode current collector and a positive electrode mixture layer containing a positive electrode active material and a binder, the positive electrode mixture layer being provided on the positive electrode current collector; a negative electrode 5; a porous insulating layer 6 interposed between the positive electrode 4 and the negative electrode 5; and a nonaqueous electrolyte. The positive electrode 4 has a tensile extension percentage of equal to or higher than 3.0%. The positive electrode current collector is made of aluminum containing iron. In this manner, the tensile extension percentage of the positive electrode is increased without a decrease in capacity of the nonaqueous electrolyte secondary battery. Accordingly, even when the nonaqueous electrolyte secondary battery is destroyed by crush, occurrence of short-circuit in the nonaqueous electrolyte secondary battery can be suppressed.

  • Patent number: 9622294
    Abstract: The present invention, as frequently practiced, represents a methodology for carrying out thermal management testing. Inventive practice provides desired temperature characteristics without incurring the safety risks associated with Lithium-ion batteries. An exemplary inventive device includes a spiral-wound electrical resistance heater, and simulates the heat generation profile within a Lithium-ion cell through the use of the resistance heater. The construction of the resistance heater is tailored not only to mimic the localized heating profile of the Lithium-ion cell of interest, but also to match thermal properties of the Lithium-ion cell (such as radial thermal conductivity, axial thermal conductivity, and heat capacity). An exemplary inventive device is constructed out of inert materials and hence is inherently safe to carry out thermal management testing, thereby obviating the need for expensive and time-consuming safety qualifications.

  • Patent number: 9455430
    Abstract: A porous bi-layer separator is composed of a first separator layer with a contacting array of non-conducting particles overlaid with a second separator layer of a microporous polymer layer, fabricated on the electrode surface of the anode of a lithium-ion battery to form an integral electrode-separator construction. Exemplary bi-layer separators may be fabricated by deposition of solvent-containing slurries of separator particles followed by solvent evaporation to produce the particle layer with subsequent application of polymer solutions followed by controlled evaporation of solvent to produce the microporous polymer layer. The elevated temperature performance of lithium-ion battery cells incorporating such integral electrode-bi-layer separators was demonstrated to exceed the performance of similar cells using commercial and experimental single layer polymer separators.
