  • Publication number: 20250250461
    Abstract: The present disclosure is related to a coating method of a long-chain entangled PDMS (LEP) gel in which self-replenishment of a lubricating layer is sustainable. More specifically, it is possible to achieve excellent slippery properties, anti-fouling performance, and anti-icing performance for a long period of time due to sustainable self-replenishment performance of a surface coated with LEP gel, by forming LEP gel impregnated with a low-viscosity silicone oil as a lubricant into the surface of long-chain entangled PDMS (LEP), in which long-chain free polymers are entangled in PDMS networks.

  • Patent number: 12334506
    Abstract: Disclosed is an electrode assembly manufacturing method, in which, in a step of stacking and pressing electrodes and a separator, the pressing is performed in that state in which pores of a porous substrate are filled with a polymer solution. The form or volume of the pores is not changed due to the polymer solution. Consequently, porosity of the separator after manufacture of an electrode assembly is similar to porosity of the separator before stacking. As a result, a battery including the electrode assembly has high ionic conductivity and excellent performance.
