Back to the Negative Electrode

Introduction

Difficulties encountered in the study of positive electrode:

	The PbO2 is more brittle than Pb and easy to break
	The mechanism of formation of PbO2 is complicated and additions of others additives makes everything more complicated
	During the polarization the thickness of lead dioxide layer is not constant =>AFM observations are affected
	Discontinuities in PbO2 layer generates reactions between Pb (substrate) and PbO2 which affect the AFM observations
	Controlling simultaneously CV (Cyclic Voltametry) and AFM observations is difficult due to the complex phenomena which occur

Because of these difficulties we decide to focus our future investigations on the negative elecrode.
