Abstract
Provided is a stacked-type secondary battery comprising a battery cell formed by stacking a plurality of full cells having a structure of cathode/separator/anode or bicells having a structure of cathode(anode)/separator/anode(cathode)/separator/cathode(anode), as a unit electrode assembly, wherein a cathode active material and/or an anode active material in two or more unit electrode assemblies are configured to have a different composition to induce a voltage difference and separate electrode terminals are installed in a battery case according to the voltage difference to thereby simultaneously provide two or more voltages by a single battery.
