Method for preparing secondary battery and the secondary battery prepared by using the same
Disclosed is a method for producing a secondary battery in which an electrode assembly comprising a cathode, an anode and a separator interposed between the cathode and the anode is accommodated in a battery case, the method comprising inserting the electrode assembly into the battery case, injecting an electrolyte into the battery case accommodating the electrode assembly to obtain a secondary battery, storing the secondary battery at a SOC of 1 to 20 for 3 hours to 10 days, removing gas present in the secondary battery, and sealing the battery case, wherein the anode comprises lithium titanium oxide (LTO) represented by the following Formula 1 as an anode active material:LiaTibO4−cAc  (1)    Disclosed is also a secondary battery produced by the method.
