More Information
Summary:A method is used for increasing the discharge capacity (Qdisch) of a battery cell provided with charge/discharge terminals to which a charging voltage can be applied with a flowing charging current. The method involves applying a plurality of charge cycles to the battery cell, each of which comprises applying a plurality of constant voltage stages each comprising intermittent voltage plateaus, and monitoring current flow. The temperature of the battery cell is monitored and maintained under a predetermined limit temperature, and the charge cycles are performed until the discharge capacity reaches a predetermined target capacity greater than the rated capacity.
