  • Patent number: 11878493
    Abstract: A polymer bilayer includes a layer of a porous fluoropolymer directly overlying a layer of polyethylene. The polyethylene layer may be porous or dense and may include an ultra-high molecular weight polymer. The polymer bilayer may be co-integrated with structures (e.g., wearable devices) exposed to high thermal loads (>0-1000 W/m2) and provide passive cooling thereof. For instance, passive cooling of AR/VR glasses under different solar loads may be achieved by a polymer bilayer that is both highly reflective across solar heating wavelengths and highly emissive in the long-wavelength infrared. The high reflectance decreases energy absorption across the solar spectrum while the high emissivity promotes radiative heat transfer to the surroundings.

  • Patent number: 9722284
    Abstract: A nonaqueous secondary battery includes an ion supply unit which supplies ions identical to ions in an electrolyte into the electrolyte at a reaction potential higher than the uncharged potential of a positive electrode. The ion supply unit includes an ion supply source which elutes the ions into the electrolyte by being in contact with the electrolyte in a state of being electrically connected to the positive electrode, and a first covering portion which covers at least a part of the ion supply source. Then, the first covering portion maintains the ion supply source and the positive electrode in an electrically disconnected state by being interposed between the ion supply source and the positive electrode, and is dissolved or disappears at the reaction potential.

  • Patent number: 9666848
    Abstract: The present invention relates to a microporous polymeric battery separator comprised of a single layer of enmeshed microfibers and nanofibers. Such a separator accords the ability to attune the porosity and pore size to any desired level through a single nonwoven fabric. As a result, the inventive separator permits a high strength material with low porosity and low pore size to levels unattained. The combination of polymeric nanofibers within a polymeric microfiber matrix and/or onto such a substrate through high shear processing provides such benefits, as well. The separator, a battery including such a separator, the method of manufacturing such a separator, and the method of utilizing such a separator within a battery device, are all encompassed within this invention.

  • Patent number: 9647255
    Abstract: Provides are a porous separator that prevents a short-circuit between two electrodes by using a porous nanofiber web where nanofibers have a core-shell structure, to thereby promote safety and thinning simultaneously. The porous separator includes: a porous nonwoven fabric playing a support role and having micropores; and a porous nanofiber web that is laminated on one side of the porous nonwoven fabric, and plays a role of an adhesive layer and an ion-containing layer when the porous nanofiber web is in close contact with an opposed electrode, wherein a portion of the porous nanofiber web is incorporated in a surface layer of the porous nonwoven fabric, to thus partially block pores of the porous nonwoven fabric and to thereby lower porosity of the porous nonwoven fabric. The porous nanofiber web has nanofibers obtained by spinning a mixture of a swellable polymer and a non-swellable polymer to have a core-shell structure.
