Abstract: Disclosed is an apparatus and method for controlling an operation of a secondary battery using a relative deterioration degree of an electrode. The method includes determining a SOC of the secondary battery whenever a pulse current flows through the secondary battery; determining an electrochemical reaction resistance from a voltage change amount measured during a preset initial time in each pulse current section and determining a lithium ion diffusion resistance from a voltage change amount measured during a remaining time except for the initial time; determining a deterioration-biased electrode by comparing a deterioration diagnosing resistance ratio, which is a relative ratio of the lithium ion diffusion resistance to the electrochemical reaction resistance, with a preset reference deterioration diagnosing resistance ratio; and adaptively adjusting an operation condition of a next charging/discharging cycle according to the type of the deterioration-biased electrode.

Abstract: Disclosed herein is a pouch-type secondary battery and a manufacturing method thereof including. The pouch-type secondary battery includes an electrode assembly; an electrode lead extending from an electrode tab of the electrode assembly; an upper pouch; and a lower pouch. The upper pouch and the lower pouch include a sealed area where the edges are sealed and an unsealed area. An average thickness of the sealed area of the upper pouch and an average thickness of the sealed area of the lower pouch are equal to each other, and the average thickness of the unsealed area of the upper pouch is smaller than the average thickness of the unsealed area of the lower pouch, so that even if the thickness of the lower pouch is reduced during the sealing process of heat-sealing, the sealed area of the upper and lower pouches are formed with little difference in thickness.
