  • Patent number: 10297860
    Abstract: Provided are a lithium secondary battery including a cathode, an anode, a separator, and a gel polymer electrolyte, wherein i) the anode includes a silicon (Si)-based anode active material, ii) the gel polymer electrolyte is formed by polymerizing a composition that includes a monomer having a functional group bondable to metal ions, and iii) a charge voltage of the battery is in a range of 3.0 V to 5.0 V. Since the lithium secondary battery of the present invention may prevent the movement of metal ions dissolved from a cathode to an anode or reduce the precipitation of metal on the anode, the lifetime of the battery may not only be improved but capacity characteristics of the battery may also be excellent even in the case in which the battery is charged at a high voltage as well as normal voltage.
