How to solve Passivation?
De-Passivation
For some applications, passivation is not a factor, and users do not notice voltage delay when hooking up to the circuit. On the other hand, If the device cannot handle this drop in voltage (i.e., reset, turn-off, fail, etc.), then the cells must be depassivated prior to use. Depassivation is composed of placing a constant load on the cell for a period of time discharging a cell near the specified maximum continuous discharge rate.
The purpose of this is to pre-condition the cell to where it does not drop below the minimum voltage of the device once the load is applied. This is done by advancing the specified maximum continuous discharge to pass the point of the voltage drop in the above chart.
