Abstract
The present invention comprises a formation procedure for alkaline nickel-zinc cells, the procedure comprising the steps of assembling an alkaline nickel-zinc cell, charging the cell at a charging current rate until a first condition is achieved, wherein at the first condition the cell has a first cell voltage, maintaining the cell at the first cell voltage while applying a maintenance current to the cell until a second condition is achieved, and discharging the cell at a discharging current rate until a third condition is achieved, wherein the steps of charging, maintaining and discharging are repeated at least one time, and, thereafter the cell is finally charged at a final charging rate until the final condition is achieved.
Claims23
A formation process for alkaline nickel-zinc cells, the process comprising the steps of:
- assembling an alkaline nickel-zinc cell;
- charging the cell at a charging current rate until a first condition is achieved, wherein at the first condition the cell has a first cell voltage;
- maintaining the cell at the first cell voltage while applying a maintenance current to the cell until a second condition is achieved;
- and
- discharging the cell at a discharging current rate until a third condition is achieved;
- wherein the steps of charging, maintaining and discharging are repeated at least one time, and, thereafter the cell is finally charged at a final charging rate until a final condition is achieved.
