Interface Reaction Energy, Average Cathode Potential and Electrochemical Stability

Dear Users and Developers,

Happy New Year to all of you. I see the Interface Reactions app on the Materials Project and feel it is a really excellent app for interface reactions on solid-state electrolytes and cathode materials. I have some questions regarding this. I would appreciate it if someone could answer the following questions:

  1. Is the electrochemical stability voltage window of cathode materials identical to the average intercalation voltage for the cathode materials (Ceder et al., Phys. Rev. B: Condens. Matter Mater. Phys., 1997, 56, 1354)? Are they connected to each other?

  2. How to choose an element reservoir? The addition of an elemental reservoir implies the construction of a so-called grand potential phase diagram.

Looking forward to hearing from you.

With kind regards,
