Abstract: Provided herein is an electrochemical cell designed for high current discharge, which includes a cathode strip, an anode strip, and at least two separator strips, being longitudinally stacked to form an electrodes set that is folded into at least four segments and designed to exhibit a ratio of its nominal capacity per its active area lower than 12 mAh/cm2, such that the cell is characterized by a discharge efficiency at room temperature of at least 30% to a cut-off voltage of ? of its original voltage at a discharge current of 1,250 mA. Also provided are process of manufacturing, and uses of the cell, which is particularly useful in high drain-rate applications as charging a cellular phone.
