  • 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.

  • Publication number: 20170034456
    Abstract: An image sensor includes both visible pixels and infrared pixels. The visible pixels produce signals indicative of light within a visible band received by the visible pixels, and the infrared pixels produce signals indicative of light within an infrared band received by the infrared pixels. A selective infrared (SIR) filter array is integrated on the image sensor. The SIR filter array includes SIR pixel filters that are positioned to filter out light within the infrared band propagating to the visible pixels. In this way, infrared crosstalk to the visible pixels can be reduced.
