Correlation between Anode Recipe and Anode Properties

The variation of anode raw material quality is becoming more and more challenging for the industry. Therefore, the anode recipe should be adjusted according to the available anode raw material in such a way that the quality of the anode remains consistent. The CO2 and air reactivities as well as air permeability are important indices to evaluate carbon anodes because they relate not only to anode density but also to anode consumption, which can help assess the anode performance. This paper presents the anode formulation tests carried out together with SEM image analysis with the objective of decreasing the anode reactivities and air permeability by optimizing the anode recipe.
