  • Secondary battery and method for manufacturing the same
    Patent number: 9240574
    Abstract: Provided is a secondary battery with improved safety through filling a polymer in a hardened state, and a method of manufacturing the same. The method of manufacturing a secondary battery according to the present disclosure includes preparing a polymer slurry by adding a polymer particle to an electrolyte solution, injecting the polymer slurry to a battery casing in which an electrode assembly is received, changing the polymer slurry to a polymer solution by heating the battery casing, and hardening the polymer solution by cooling the battery casing.
    Type: Grant
    Filed: February 20, 2014
    Date of Patent: January 19, 2016
    Assignee: LG CHEM, LTD.
