  • Publication number: 20240145719
    Abstract: A binder solution for an all-solid-state battery, an electrode slurry for an all-solid-state battery including the same and a method of manufacturing an all-solid-state battery using the same, and more particularly to a binder solution for an all-solid-state battery, in which a polymer binder configured such that a non-polar functional group is bonded to the end of a polar functional group is used, whereby the polar functional group is provided by a deprotection mechanism of the polymer binder through a thermal treatment, thus increasing adhesion between electrode materials to thereby improve battery capacity and enabling a wet process to thereby reduce manufacturing costs, an electrode slurry for an all-solid-state battery including the same and a method of manufacturing an all-solid-state battery using the same.

  • Patent number: 7142027
    Abstract: Provided are a delay locked loop (DLL) using an oscillator and a counter and a clock synchronizing method. The DLL converts cycle information of an input clock signal into digital information using the oscillator and the counter and generates output clock signals from the input clock signal using the digital information after a predetermined delay time elapses. The output clock signals each have a duty cycle of 50%.
