3es and 2es
-
CV (cyclic voltammetry)

Dunns analysis

diffusive
if b value close to 0.5, signifies diffusion control dominates. b values close to 1 signifies diffusion limiting prominent.
normally used to differentiate capacitive current (diffusion limiting) / diffusion controlled current
commonly applied in 3-es for initial characterization & understading of the material electrochemical behaviour

kirkendall effect: 2 distinct materials are placed next to each other & diffusion is always to take place bet, them. diffusion coefficients of 2 mat. in each other are not the same. large surface area with multiple oxidation states favors a rich electrode-electrolyte interface, regulates stacking of layers, reduced agglomeration, readily available pores for charge storage, and modulates electron transport path
