Abstract
The invention disclosed is a method for decreasing the internal resistance or impedance of a battery or electrochemical cell is described which comprises the step of discharging the battery or cell until it reaches an overdischarge condition and maintaining the battery or cell in the overdischarge condition for a period of time sufficient to effect a diminution of the internal resistance or impedance of a battery or electrochemical cell; and a battery or electrochemical cell having a reduced impedance.
