Circuit
If the voltage of each cell during charge exceeds
4.5 volts. gas may be generated due to the
dissociation of electrolytes. this may cause the pressure inside
the cell to rise, and
the pressure releasevent (safety vent) opens and by which electrolytes
leak out.
Also, if the cell voltage drops too low (below 1.0V), the copper
collector of the negative electrode begins to dissolve into
electrolytes, and the cell's performance deteriorates.
The cell must be used as a battery pack equipped with a protection
circuit module that
performs the following functions.
