The context is as follow:
The environmental impact flows of the syntheses of LiFe0.98Mn0.02PO4/C and LiFe0.98Ti0.02PO4/C are diagrammed in Fig. 3 and Fig. 4, with the corresponding EIm of each material is labelled in the material box.
Is the use of the comma correct or how to restructure this sentence for clarity?
Thanks for your time.
The comma is the only thing I understood.
