  • Publication number: 20200168855
    Abstract: A secondary battery configured to have a structure in which an electrode assembly is received in a battery case together with an electrolytic material, wherein the battery case is provided therein with a space for receiving the electrode assembly and wherein the battery case is made of a thermoplastic resin, which can be injection-molded. An injection mold may be formed such that the size of the mold corresponds to the thickness of the electrode, thereby solving a problem in which the formability of a conventional laminate sheet including a metal layer is low. In addition, a process of forming the laminate sheet and a process of sealing the battery case using a pressing member, which are essentially required in order to use the laminate sheet, may be omitted, whereby a manufacturing process is simplified and thus productivity is improved.

  • Patent number: 9344627
    Abstract: An image sensor includes a pixel array and an analog-to-digital (A/D) conversion unit. The pixel array generates an analog signal by sensing an incident light. The A/D conversion unit generates a digital signal in a first operation mode by performing a sigma-delta A/D conversion and a cyclic A/D conversion with respect to the analog signal and generates the digital signal in a second operation mode by performing a single-slope A/D conversion with respect to the analog signal. The image sensor provides a high-quality image in a still image photography mode and a dynamic image video mode.
