Abstract
A lithium secondary battery is provided in which even if the depth of discharge becomes deep, lowering of an power is small, and charging and discharging characteristics are excellent, and which is suitably used particularly as a battery for driving a motor of an electric vehicle or the like. In the lithium secondary battery, an internal electrode body formed by winding a positive electrode and a negative electrode through a separator made of porous polymer is contained in a battery case, and an organic electrolyte is used. An power at a depth of discharge of 80% is not smaller than 60% of an power at a depth of discharge of 0%.
